Sennheiser Momentum Review on Technology X

I met Les Tokar the founder of Technology X and The SSD Review a couple days ago and we decided that I will write articles for them from time to time. This may grow into something even bigger but the current plan is to post single headphone reviews on Technology X and in depth comparisons on AudSpace.

Sennheiser HD 419 Review

I would like to thank Sennheiser Canada for providing me with these headphones to review and to inform everyone that these were provided by Sennheiser for me to review.

Pros

• Punchy bass that should satisfy most bassheads
• Great soundstage
• REALLY LOUD! For those of you who enjoy abusing headphone drivers these things can go to speaker-like levels fairly easily.
• Sleek and streetwise looks
• Durable headband (See picture in review)
• Toned for more "mainstream" genres (pop, hiphop)

Cons 

• Not analytical at all, if your goal is precision audio reproduction, look elsewhere
• Drivers are slow and lack separation for quicker songs
• Thin cable

When looking at these headphones, the words target audience is key. But to understand that, a bit of simple marketing knowledge is needed (skip the points if you don't really need to know):

• When designing a product you have to keep in mind who you want to buy the product
• Look at what that group values
• How are you going to make that group interested in your product
• Why a consumer would take your product over a competitors

Now after listing  all that I would think that most of the people reading this right now would belong more in the "audiophile" group, those who value sound quality above all else. I can tell you right now, THESE HEADPHONES ARE NOT FOR YOU! They were not designed to compete with the headphones you would find on the "audiophile" market (ex. Shure SRH series, Grado SR80i/SR60i) these were designed more for the general public, or rather the teen market("street" brands like Skullcandy or Beats). So I'm going to answer this right away, if you can forfeit features for most accurate sound reproduction (including isolation, leakage and cable length), there are better choices.  But if what you're looking for is something a little more streetwise, toned towards mainstream music and something that will survive everyday abuse, the HD419's are something you would want to consider.

A little side note, things to consider about these headphones:

• Designed for teens
• Teens generally prefer mainstream genres (pop, hip hop)
• Active life usually means poor product care

When it comes to review music these headphones have absolutely no synergy at all with almost anything audiophiles would consider "reference". Stuff like bluegrass jazz and classical sounds fairly distorted and odd to my ears with the HD419. Switch over to mainstream genres like rock, pop, hip-hop, and dance (to name a few) these headphones come to life.

Overall sound

The HD419's are really laid back with lots of energy in the lower frequencies very nice for the teen who loves to go "NEEDZ MOAR BASS!!!!!!!" but without compromising much of the mids and highs. These are ultimately effected though and I do notice the mids being veiled by the bass on a few occasions. Now the biggest problems I have with these headphones are clarity and speed/separation. Overall these problems are still around but are a lot less noticeable with more mainstream genres. To me these headphones sounded a tad muddy and lacks the clarity of analytical phones in it's range like the Grado SR80i's or the Shure SRH440 but improves a decent amount over the Skullcandy competition. The sound of the HD419 goes more for enjoyment over reproduction, when I play music by people like Glenn Gould and Miles Davis distortion becomes really apparent. Switch over to more mainstream genres and I have no problems at all. Now being an analytical person who's heard a number of quality headphones I notice these flaws, but to non-audiophiles, these are solid headphones.

Reactions:

Twin Brother's: "These sound better than my Skullcandies 0_0."

Friend: "Hmm not bad *takes headphones off and turns to max volume*... Hey look! I can use them as speakers!"

Basshead: "Not bad, it's got bass... but Beats are better."

It has a really laid back sound signacture that never feels too aggeressive to my ears and kinda reminds me of the IE8's. The soundstage feels really pushed back and is never upfront.

Bass

Anyways going a bit more in depth with the sound, the basshead has a point, these headphones have bass. These headphones have a good amount of bass, enough to satisfy a basshead. When you compare the HD419's bass level to more analytical headphones like the SR80i and the SRH440 the HD419's just blows them out of the water in terms of bass quantity, but falls behind a little in bass clarity.The packaging itself claims that these headphones have "punchy bass" and they really do have punchy bass. In general the bass gives off a muddy but impact, it lacks clarity but definitely gives off a nice BOOM. I find bass drum impact on some tracks lacking though, it tends to be aired out and lacks driving force behind it, but this is only for a few tracks though. Overall these headphones great bass response, leaving a bit to be desired in clarity but still beats most of it's competitors.

What I find in terms of bass:
Street brands (ex. Skullcandy): Muddy and plentiful
HD419: Not too muddy, but fairly impacting 
Analytical: Clear but lacking

Mids

When I first listened to the mids of the HD419, I was fairly happy, not drowned out by the bass and fairly clear. After a little time goes by I noticed that the mids, even though they were clear, they sounded veiled. To my ears, the HD419 sometimes sounds like a speaker with a thin piece of foam blocking it and at other times sound distant and pushed back. Though percussions in particular on these headphones are very vibrant and have a fairly strong impact.

Treble

The treble's description follows the mids, laid back and a tad veiled. For those who have heard the IE 7's this is you will understand when I say the treble is clean but it sounds sharp and aggressive. This is the exact opposite, rolled off near the end and feels slightly overshadowed by the bass.

Durability

 The pictures can help me do the talking.

***RESERVED FOR IMAGE***

When I first took these headphones out of the box, I was a tad disappointed. Being a street line headphone, I was expecting some type of storage to come with it, even if it was a little pouch. But after using them for a month or so I want to totally disregard this point as there is just no need for any accessories of the sort.As long as you don't run these headphones over with your car or put them through a 20 foot drop the only damage you will ever do to these headphones are minor scratches. In order to test the durability I put the headphones in my bag in front of my textbooks and laptop when I need to carry it to school. Something I usually wouldn't do if I wasn't fairly sure they would survive.

The headband also can also bend like crazy, (see the picture above) so pretty much unless you deliberately try to twist and break the headband there is no way it will break.

As I have already mentioned the cable was a point of interest for me because it was so thin, but it seems to be able to take a fair amount of abuse (much more then the standard iBud).

Final Notes

When I first listened to these headphones I already knew that I had to take a different approach to review these headphones because these headphones were not designed for audiophiles so I can't say that these headphones are going to revolutionize the audiophile world because they won't, heck they will be trampled in it. But bring it into the world of iBuds and Skullcandy, you bring in a powerhouse to play with the minors. I would really consider this headphone to be more of a stepping stone to better  audio as it provides iBud users with the speaker-like sound that they are accustom to while adding detail and soundstage.On top of that, the HD 419 perform better than many other street line products in its products (to my ears anyways) as it provides a more dynamic and balanced sound.

Things to Take Note of:

Frequency response (headphones)	20 - 20000 Hz
Cable length	1.4 m single-sided OFC (Oxygen Free Cable) cable
Impedance	32 Ohm
Sound pressure level (SPL)	108 dB (1kHz/1Vrms)
THD, total harmonic distortion	<0.1% (1kHz/100dB)
Ear coupling
Transducer principle	Dynamic, closed
Jack plug	3.5 mm gold straight

Why so many Sennheiser reviews?

So my friend looked at this blog, and he asked me, "Why do you have so many Sennheiser reviews?"

And yeah I totally agree with what he says, but is this because I favor Sennheiser? Nope, its just because those are just the headphones I ended up getting in this amount of time due to bump ups, gifts from family and most importantly sponsorships/review samples so they are my first priority.

Currently I can see about 2 or maybe 3, if I'm lucky, more Sennheiser reviews in the recent future, but neither are coming any time soon (2 weeks at the least) so the next few reviews that are coming out (I'm currently working on them) are going to be on the infamous Beasts Studio and Bose On Ear (original one)

Sennheiser IE 8 Review

Pros

• Overall excellent sound
• Bass knob (but you won't use it much, trust me)
• Improved highs over the IE7's
• Extremely ergonomic shape
• Removable cables
• Durable case that looks nice when placed on a desk 
• Excellent soundstage 
• Earhooks take a lot of playing with to get right

Cons

• There is a mid bass hump which may become distracting at times, but you can EQ that out
• PRICE!!!!!!! 
• Ear clip is real annoying to get right and easy to lose if you use it together with the shirt clip
• Bulky case  is not really pocket friendly
• isolation is moderate, sometimes its more then enough but may also be a little lacking depending on the situation 
• you can't use the bass knob without taking off the headphones or without the tool 
• nickel coated jack (microphonics are acceptable but still gold plated would have been much better especially for a pair of headphones at this price) 
• mids and highs seem a tad veiled as they are not really upfront and engaging 

Comparison between the IE 7's and IE 8's

What the IE 8's have over the IE 7's

• Bass knob
• Detachable cable
• One more type of ear adapter
• Better highs
• Better soundstage

What IE 7's have over IE8's

• cheaper price
• mids/vocals are more upfront (personal preference but I think hearing a tad more vocals on the IE 8's like the IE 7's are better)

Everything that comes in the box

Honestly sound-wise the IE 8's are definitely better but it depends on if you don't plan on a cable upgrade or don't mind changing not being able to change the bass, the IE 7's are perfect (shame it's gone).

The IE 8's themselves are nearly identical to the IE 7's in sound with the exception of the bass hump and the improved highs. But there are still differences.

Appearance and Cosmetics

Now as you all may have noticed, the appearance on Sennheiser's IE line is rather odd for an IEM. They seem like they're a tad wide and may be uncomfortable because of their awkward shape but there are actually a few reasons for this:

• Sennheiser chose to use dynamic drivers instead of the multiple armature drivers other high and mid end IEM's use, so the larger drivers take up more space.
• The shape helps with helps with the ergonomics of the headphones because, especially in the case of the IE7, the earbud is actually supported by the lower part of your ear making it incredibly comfortable and even harder to come out (its hard to explain so bear with me until I can get pictures).

Highs

The highs have definitely improved over the IE 7's sound as the speed of the treble has improved, it sounds clearer and doesn't seem to have that problem with sounding harsh. They sound nice and crisp and there is that nice sharp sound the treble should have.Though still not enough to compete with the HD 558 treble, which I would say is nearly unrivaled until you get the the high end 600+ spectrum.

Mids

You have the crisp and nice mids that you would expect from a high end headphone, though I found the IE 8's mids to be less engaging and outspoken when compared to some other headphones I've listened to like the Shure SRH 440, HD558, HD 650, or the IE 7's to name a few and took a little getting used to. In my opinion the mids can stick out a little more to prevent a small "veiled" effect that I found at times. But overall, they are still very much enjoyable but my personal preference tells me that these headphones would be just so much better if they weren't so laid back.

Bass

YOU HAVE A FREAKING BASS KNOB! But I do regret to tell you that this is a feature that you will most definitely rarely use except for EQ'ing your sound. I find the bass knob useful for when changing between genres but I barely use it as the IE 8's on lowest settings are more then enough.

So you have 5 bass settings, I'm not going to go into how each of these notches sound like but basically from it goes from a HD 558 sound signature to the near  unbearable Beats Studio, I just want to run out of my house and scream, sub-woofer level.

The Sennheiser IE 8's in the case

Now here is a little compairison of bass to all of you who may not have heard either of these headphones. For knob 1, its like you're listing to your average headphones/speakers with a balance of bass, mids and highs, but when you are on the 5th knob, you get nearly overpowering bass that makes a song like Maroon 5's Makes Me Wonder have ground-shaking bass.

The physical bass itself is nice and tight but it may block and mask some of the tiny details.

Just a friendly warning just in case you are tempted to listen to any bass heavy song with highest bass knob setting, beware that you may feel like that you're brain may be melting from the low rhythmic rumble of the bass simulating an earthquake around you.

The Infamous "Bass Hump"

The bass "hump" is referring to an "issue" to the frequency response which has a mid bass hump which veils the mids and highs making them sound veiled and recessed. Though this can be fixed a bit by lowering 150Hz frequencies by a few dB it still the mids will still sound a little veiled. Just to make sure we're all on the same page here, when I use the word veiled here means the bass sounds a little like it's a bit louder or on then the other frequencies. This might not be a bad thing, but sometimes it might seem the vocals are "too far back" or mixed with the music a bit.

Soundstage

Now going back to my statement about closed headphones, even though the IE 8's are closed and noise isolating to an extent, they still sound like they're coming from a speaker in the room, the headphones still feel like they're giving off 3D sound from about 3cm away from your ears. The soundstage is really dynamic on these headphones and it doesn't just seem like the sound sound is just coming from earbuds in your ears, but more like sound coming from around  you. There have been times that I thought some of the sounds in a song were sounds leaking in from outside and actually look over in that direction. So in my opinion, these headphones have amazing soundstage that can beat or rival most headphones. I swear, there are soo many times I've looked behind myself to see if a sound came from behind me.

Overall Impression

Being a person who usually listens to headphones/audio sources that have really upfront mids and highs, the IE 8's take some getting use to, but after that, they sound absolutely phenomenal. Comparing them to the IE 7's and other headphones, I find that the extra $120 or so that you may spend is very justifiable if you can afford to pay the extra as the improvements in sound and the extra features you get make this a very nice upgrade from almost any headphone. I find that this is a very user based headphone as you have the option of adjusting the sound as well as having the freedom to re-cable your headphones to increase their longevity and improve their sound depending on the quality of your new cable. The isolation is kind of iffy for me depending on where I am and what tips I'm using but it's generally adequate for every situation you may be listening to music to (with the exception of in the busy city, which is not a bad thing as it can become a serious danger hazard). I really love how these headphones manage to give you amazing sound without an expensive and/or bulky setup to run at its full potential, so I think that these are the perfect headphones for you if you're someone that tends to travel a lot and has high expectations for sound (businessmen and students, you'll like this one A LOT).

Effects of Burn In

Burn in, as I have already said in the Audio 101 is a phenomenon affects dynamic drivers. I've seen many who have said that the IE 8's suck and sound like a pair of, quote, "$40 headphones". I don't agree with them sounding that bad out of the box, but they definitely don't sound like $400 headphones either. Even though burn in isn't confirmed by or spoken of by any audio company (at least as far as I know of) because of various different reasons, it is clearly evident that it affects the IE 8's. With burn in, the bass hump and bass level improves along with the soundstage just to name a few. Currently I have about 100 hours of burn in on my IE8's and it's still changing so it's definitely true when people say that these headphones need 200+ hours of burn in.

Things to take note of:

Tranducer type: dynamic

Operating principle: closed

Frequency Response: 10-20,000 Hz

Impedance: 16 ohms

Cable Length and Termination: 1.2m cable 3.5mm

Sennheiser IE 7 Review

 Well it is sad to say but the IE 7's have been discontinued  by Sennheiser, it sucks but it's true.

The Sennheiser IE 7's

Things to take note of:

Tranducer type: dynamic

Operating principle: closed

Frequency Response: 10-19,000 Hz

Impedance: 16 ohms

Cable Length and Termination: 1.2m cable 3.5mm

Pros

• Mid based headphones that have great dynamic balance that does well with all genres 
• Bass is NEVER too strong or too soft and is enough to satisfy almost any basshead (if it has enough bass to satisfy a Monster Beats user, it can satisfy anyone).
• Closed headphones that can block out most noise from every day life (it blocks out the noise of the car as well as people talking and the sound of an action movie on a road trip)

Cons

• Treble, the treble is always detailed and clear but there are a few rare times where the treble just seems a tad rough or raspy.
• The case is just a decoration/storage, it is a tad too big and bulky to be carried around in a pocket and it's kind of annoying if you want to wrap the cable up properly so the cable doesn't curl, something that could have been more travel friendly would have been a lot more convenient.
• Nickel coated jack, this means bad microphonics so this means you will definitely hear the crackling sounds when you move the jack in a high powered source (ie computer/laptop) but you are relatively fine with something like an iPhone.

What the IE 8's have over the IE 7's

• Bass knob
• Detachable cable
• One more type of ear adapter
• Better highs
• Better soundstage

What IE 7's have over IE8's

• cheaper price
• mids/vocals are more upfront (personal preference but I think hearing a tad more vocals on the IE 8's like the IE 7's are better)

Honestly sound-wise the IE 8's are definitely better but it depends on if you don't plan on a cable upgrade or don't mind changing not being able to change the bass, the IE 7's are perfect (shame it's gone).

The IE 8's themselves are nearly identical to the IE 7's in sound with the exception of the bass hump and the improved highs. But there are still differences.


Overall Sound
So I haven't really listened to the others in the IE line yet, but according to most, the IE 7's are the most neutral and the least bassy of the three in the IE line, so does that mean that the IE 7's have little to no bass? HELL NO! These headphones have more then enough bass to satisfy people (I have yet to see someone who was under satisfactory in the bass department). These headphones are promptly mid based leaning towards the darker side with nice highs that added nicely to the background.

Highs/Treble
The highs are amazing overall but the treble is something that could definitely use some tweaking. So the highs are just like most of you would expect from a pair of Sennheiser headphone, not going to exaggerate on it too much, the high ends of the vocals stick out beautifully but the treble was rather annoying at times as I found them a tad harsh at times when the cymbals are hit at a quick rate.

Mids
The mids were definitely the focus of these headphones and has beautiful mids, ie vocals and guitar (both electric and acoustic) that would more then match my HD 558's. You are literally able to pick out when each string is struck and even when the fingers slide across the strings of an electric guitar in some acoustic songs. But for sure the vocals was what stuck out the most on these headphones. These headphones also seem to like main vocals a lot more then background vocals and likes to project them a lot more. But unlike the 558's where they just stick out like a sore thumb, on the IE7's they it sounds more balanced out as the other mids and bass.

Bass
The bass is, according to many people who have listened to all three of the headphones in the IE line, they all say that the IE6 has the most bass (if the IE8's are on a reasonable bass level) while the IE7's are the most neutral and have the least bass. But as I have already stated, never let this be misleading to any of you, the IE7's have plenty of bass that can at least satisfy most people. When it comes to the IE7's vs the IE8 in bass, the IE7's bass seem to be around notch 1-2. The bass is really smooth and really complements the nice mids of the headphones.


Overall Impression

These headphones would probably be the most balanced of the three brothers (in one fixed configuration that is) as the IE6's would be best at rock, pop, hip-hop and other mainstream genres, the IE7 would be more for those who listen to country and classic rock, but it can still easily handle other genres and is definitely the more versatile of two as the bass level is already fairly near the line where more bass would just ruin country music for me. Basically I'd say if you have the money and you can still find a genuine pair (beware of counterfeits!) this would be an excellent purchase.


I'm also fairly sad to tell you all that there won't be an IE7 equivalent in the IEx0 line (hopefully somewhere in the near future they will announce one) but until then, your best bet at a genuine IE7 would be at Dakmart, a legitimate Sennheiser dealer which deals mainly with refurbished and products and discontinued products(but they do also have new products). So if you have the chance, you may want to check these out.

Sennheiser HD 558 Review

Pros

• The HD 558's are insanely neutral sound signature, they focus almost evenly on the mids and highs with really strong and detailed bass to back it up
• These headphones can handle all types of music due to its neutrality in its sound signature
• Open design on these headphones make anything you listen to appear like it is coming from outside the headphone
• Life-like acoustics
• Airy bass (perfect for bass guitar reproduction)  due to open design

Cons

• The HD 558 are not designed for portability in any way this is shown by how Sennheiser made these headphones:
• Open design leaks more noise out and lets more noise in (not enough so that louder volume can't compensate for but still can be a tad annoying)
• The jack is 6.3mm and the adapter is huge so if you have a case for your player, it may get in the way
• The cable of the headphones are 3m long, so if you want a shorter cable, I suggest you use a cable tie or something to keep it bound (avoid rubber bands, they can damage the cable due to the pressure it outputs) 
• Fails to produce impacting sub woofer-like bass without assistance(bass booster)

This was the first pair of audiophile headphones that I owned (not the first one that I used, but the first for me to own).

So my school laptop is just horrible when it comes to sound card and cant bring the colour and detail out of these headphones but the output is perfect for these headphones, what i noticed when these headphones are properly powered are these headphones are LOUD!!!

The first thing you would notice about these headphones would be how comfortable they are, followed by how little noise they block out, the annoying 6.3mm jack and the 3m cable. All the characteristics of a pair of headphones that is meant for studio use. 

Sound Frequency Chart

The Overall Sound:

the sound of these headphones will definitely sound familiar and it sounds very much like the time i tried on my friend's HD 555's mainly focusing on the mids, highs and the treble and detailed bass without the bloating (some of my friends get ticked off at that [but they use the Beats Studio so its understandable]). But for those who used the HD 555 will notice that the 558's are actually more dynamic in sound/has better soundstage, not sounding as flat as its predecessor.  This headphone has a fairly neutral sound signature that leans towards the brighter side of the sound spectrum. This headphone focuses mainly on the mid tones with strong highs and detailed bass to support it.

Highs

these headphones are rather neutral headphones leaning towards the brighter side, in this review, I use the word neutral because it is within the range where none of the tones seem to be overpowered, drowned out, or too soft to be audible, I mean it is a near balance between the three tones (highs, mids and lows). These headphones truly accel at the highs. The first thing you would notice is these headphones make vocals seem like they are coming from outside the headphone and acoustic sounds sound like they're coming from a guitar about a meter away from you.

Mids

OK big improvements here, there isn't that gap I've noticed with the 555's and they have made the mids on these headphones to really stand out on these headphones (but not so that it can sound overpowering) the mids are just as detailed as the highs but are more "background" then some other headphones. Persecution instruments are more background then instruments like vocals and occasionally cymbals, while higher mids like electric guitars and similar digital noise (such as the intro of Don't Talk to Strangers by Hedley) stick out brilliantly right behind the vocals.

Bass

These headphones almost hit the bass sweet-spot for many songs where you both feel and hear the bass. But saying this I find these headphones rather bass-lacking for some songs like Flo Rida's Low where sub woofer bass impact is needed to make the song really enjoyable, that is without bass booster which I generally dislike for distorting the rest of the song to increase the impact of the bass. Having said that you shouldn't expect teenage sub woofer bass performance bass from these headphones without any personal tweaking. Pardon the contradicting statements but I am nowhere close to lying when I say these headphones almost hit the sweet-spot of bass. These headphones are absolutely amazing at recreating a bass guitar's sound, unlike most closed and semi-opened (with a small hole) you get an airy bass guitar sound which is almost essential for a bass guitar to sound like a low guitar and not a low sub woofer-like sound. As I have previously mentioned in my headphone 101, bass is usually traded off depending on the type of headphone you go with.

Treble

These headphones have the strong treble of the Sennhieser soundstage clear, detailed and very apparent. This was probably the first thing I noticed about these headphones was how clear, detailed and realistic the treble sounded on these headphones even on an unamped iphone. i find that on a few rare moments in about 5 songs in my 2000 song library that the treble can even sound a tad overpowering covering tiny hints of the mids or highs. For those who don't like listening to the cymbals as much, and on a few rare occasions, even more then the drum, these headphones may not be for you

foam mod

Ok my friend did the foam mod on his pair of 558's so I decided to give them a try. This mod helps a lot with the bass and it is something bass-heads might want to try. But the downside of this mod is a small loss of control in the highs, mids and bass. I have been noticing some notes are not as vivid, i will do this mod again to confirm this but i want to get some adequate equipment first.

The infamous cracks

Build Quality

The build quality of these headphones is almost totally reliant on when you get them. Sennheiser has had constant problem with their 5xx series headbands and the same applies to the early 558's. My HD 558 were purchased early December and the cracks started in late March, I swear I was flipping out. But Sennheiser has claims to have fixed the problem in the stocks that arrive in June (depends ultimately on your store). The new material is supposedly more rubbery as opposed to the old brittle plastic that cracks when stressed too much, but I can't confirm this until I get my HD 558's repaired. On the side you can see a picture of the cracks as they start. The best way to tell if you have this problem is you hear a cracking sound as you move the headphone joint it makes it really obvious that there is a problem.

Overall Impressions

Well when I re-wrote/revised this review I totally forgot about this section. So I'm writing this now after my HD 558's are gone so I have the funds to acquire the HD598's for a comparison between the two. Anyways, these headphones are a dream to listen to and can make even the crappiest of sources (like an iPhone/iPod or on-board sound card) sound amazing. The low impedance makes it drivable by just about anything and comfort is near god-like with it's velour ear pads. These headphones will have a fairly familiar sound signature to anyone who has enjoyed the HD 555's but with more dynamic and dimensional sound and a sweet looking colour scheme. For you new to high end headphones or for those of you who stuck with Beats, Skullcandy or Bose, I really recommend getting these headphones to get you started with high end audio.
