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.
RHA MA350 Review
Pros
- Extremely active sound signature that brings the most out of lossy audio
- Prominent bass that does not overshadow the overall sound signature
- Generally smooth treble
- Does an amazing job expressing details for it’s price range
- Build quality is amazing for the price
Cons
- Treble is extremely active and sometimes it can become stressful to listen to
- Things can sound like a jumbled mess on more active tracks
General Overview/First Impressions
The RHA 350 is RHA’s entry model IEM mostly aimed at the
average consumer, mainly those looking for a nice replacement for those white
iBuds. Being priced at $39.99 there are plenty of similar products that compete
for the consumer’s money and there are very few whose sound quality is decent
enough to write a worthwhile review, well needless to say the MA350 is one of
those few. In a market as crowded as the $20-$50 market first impressions and
appearance is usually what makes the sale. The MA350’s package isn’t flashy or
particularly special but it does a good job showing the quality of the IEM. The
cord wire sleeve for the cable and aluminum earbuds does a great job of giving
a quality feel to the IEM and makes a lot of it’s competitors feel a little
cheap in comparison.

Overall Sound
Treble
The treble on the MA350 have a very noticeable exaggeration
which present itself quite prominently on the right tracks. This exaggeration
begins in the mids and grows slowly toward the treble. I find this rather smart
as it helps offset treble detail that is usually lost during lossy compression
as well as to make sure the bass does not overshadow it. This tuning makes the
treble is really aggressive on some treble prominent lossless tracks and makes it
feels like the treble is blaring at you. The MA350 are rather weak with fast
consecutive frequencies that are in the treble region which generally turn into
a muddled sandy mess this is usually hidden fairly well this fact is fairly
well hidden by the sharp attack the MA350’s treble delivers that tends to
shadow it’s successive tones. When listening to cymbals on lossless tracks the
initial clash is generally overshadows the its proceeding tones and hides them
very well. This sharp and occasionally, blaring attack does a great job at
bringing out the treble but can really wear down the ears during a long
listening session. While they are still
present, most of these problems are a lot less prominent on lossy tracks as
most of those peaks are lost during the compression process. As a result the
treble ends up providing support to the more prominent mids and bass and the
exaggeration ensures that the rest of the sound signature doesn’t drown the
treble out.
Mids
The mids of the MA350 are very well done and are almost
never overshadowed by the bass or the treble due tracks generally prioritizing
the mids or vocals over everything else. It does a really good job pronouncing
details that are usually lost or overshadowed by the main vocals such as the
backup vocals and they do a fine job showing minor repeated tones that would
usually be jumbled up into a cluster of sounds in this price range. The MA350
do a fine job allowing the vocals to shine through in its relaxed sound
signature very well but they tend to struggle a little as they near the lower
mids and upper mids where the exaggeration for the treble and bass begins as
they tend to lose out or fight for dominance but this rarely occurs and is not
much of a concern. Though I found that the vocals can get rather harsh as they
begin to enter the treble region and harder tones like “s”, “st” or “sh” became
really harsh and can create a little stress for the ears. While this problem
generally occurs a lot more often when listening to lossless tracks it also
occurs on a few compressed tracks.
Bass
The MA350 bass is the aspect that makes the MA350’s sound
signature so fun to listen to. The MA350’s bass is clearly exaggerated which
gives the MA350 a rather relaxed and warm sound. Generally speaking, the MA350
have smooth, prominent, deep bass that feels a lot more controlled and tight in
comparison to most IEM in its price range. In budget IEM I usually find the
bass is lacking in depth, control or both and when the IEM has a bass prominent
sound signature these flaws tend to show even more. This is why I so impressed with the even with
the bass exaggeration I notice little to no loss of bass control. The bass of
the MA350 is rather revealing and tends to show details that are usually lost
or sound faint on other brighter IEM making it a very fun and entertaining
switch.
Final Thoughts
The MA350 are a phenomenal budget IEM that has a very fun
and generally relaxing sound signature that does a great job at reproducing
details. The build quality is amazing as it feels durable and feels like it was
built to last. With a $39.99 price tag it makes a great gift and is a great
first step into better audio.

Brief Impressions of the AS-2
As for the possible mods for the ASG-2 I have not run into any major problems worth noting so far I would suspect that the AS-2 may sound a tad better in this respect as they may not exist on my AS-2 because they're custom and are better tuned as they take into account how sound enters my ear.
ASG-1S Review
 |
| Copyright 2013 Aurisonics, Inc. |
Pros
- Luxurious aesthetics
- Ergonomic design
- Impacting bass
- More balanced sound signature vs ASG-1
- Vocals are incredibly detailed and prominent
Cons
- Sound is coloured
- Sounds best with EQ
- Treble is a tad soft without EQ to help bring it out more
General Overview
The ASG-1S are a set of limited run IEM which are handmade
by Dale Lott (Owner and CEO of Aurisonics for those who don’t know) and cost
$499.99 a pair. Each pair of ASG-1S have polished shells and chrome plates as
well as their own serial number. Sound-wise, the ASG-1S are set apart from the
regular ASG-1 as it is tuned differently with a tuning Dale calls “signature”
tuning so they don’t sound exactly the same as the ASG-1(rev 1 or rev 2). Being
a separate product, the ASG-1S will most likely have their own set of revisions
in the future separate to the ASG-1.
Aesthetics
Generally, my first impressions of a pair of headphones
start with the sound, with the ASG-1S, it was a totally different story. When I
first opened the ASG-1S I stared at them
for at least 30 minutes because of the gorgeous finish on these. The polished
shell is just about clear as glass except for the sound bore and the housing of
the drivers that still remain frosted like the ASG-1. While the main highlight
of the ASG-1S’s aesthetics are definitely the polished shells and the chrome
plates the cables were what really caught my eye on the ASG-1S. Now for all
those who read my revised ASG-1.1 review, you may remember that I mentioned I
really hated how the cables turned green (caused by the copper in the wire
oxidizing).
Overall Sound
The ASG-1S, like the regular ASG-1’s were designed as stage
monitors and the tuning reflects that. When Dale designed the ASG-1, his main
goal was to create stage monitors that would play back a vocal’s voice as
others hear it which is why the ASG-1S do sound coloured. I am sure everyone
has noticed that your voice sounds different when you hear it coming out of a
pair of speakers, the ASG-1S were tuned to counter this effect. This tuning
makes the midrange to sound veiled and toned and while this is rather evident
it is nowhere near the severity of the original ASG-1.1 which had a radio like tint
on the sound. The ASG-1S have a really warm and intimate sound signature with
prominent bass backing up the emphasized mids and distant treble.
Tonal Difference Between the ASG-1S and the ASG-1.2
The ASG-1S have handpicked drivers which give the ASG-1S a
improvement in sound as the bass is a little more tame which means they shadow
the midrange and the treble less giving the ASG-1S a more balanced sound.
Treble
I find the treble to have a reasonable improvement over the
ASG-1.1. Even though the drivers are the same, I found the details of the
treble on the original ASG-1 was constantly overshadowed by mids and bass even
when I used EQ to bring out the treble it would tend to distort the tone of the
treble by a bit. The tuning of ASG-1S seems to fix this problem as the toned
down bass allows the treble to shine through a bit more. While that is the case
I still find dull and lacks the edge that makes it sound a tad grainy at times.
Without EQ to balance out the sound signature the treble usually sounds and
audible without any real loss of quality or detail but using EQ to balance out
the mids allows the treble to show a little more sparkle.
Practicality of the Toned Down Treble
Besides contributing to the overall tuning of the ASG-1S
there is also a very practical reason for toning down the treble, sibilance.
Now I’m sure we all have had personal experience with feedback where a microphone
has been placed too close to an output source which results in an extremely
harsh high pitched tone being outputted. Now imagine this happening during a
recording session, if the treble was left at regular levels would have this
sound played full blast directly in your ears.
Mids
The ASG-1S puts a lot of emphasis on the mids as the ASG-1’s
were originally designed for vocalists. The ASG-1S are tuned so the mids,
specifically vocals, will be the most prominent sound when listening to just
about any track. This tuning makes the mids, but more specifically the vocals,
sound really close and intimate but also make the mids feel a little bloated
and a little out of line the treble and when combined with the bump in the
upper bass it gives the mids a slightly coloured feel as tones entering the
bass range are being pushed to the front of the soundstage with the mids. While
the mids themselves are more then capable of showing details there are some
occasions where the tuning on the bass overshadows and colours these details,
which is why I generally use EQ with the ASG-1S. Using EQ to bump down the mids
bump expands the soundstage and brings the mids and the bass back in line with
the treble and allows the mids to shine a lot more and be much more revealing
as they no longer struggle for dominance. Like the ASG-1, the ASG-1S does
extremely well with acoustics and percussion instruments and makes it very easy
to distinguish between nylon and steel strings as well as reproducing the decay
of each instrument.
Bass
The bass of the ASG-1S is noticeably tighter then the ASG-1
but it doesn’t break away from the overall loose relaxed bass of the ASG-1. The
ASG-1S has very strong prominent bass and does a real good job at accurate but
loose bass reproduction. The ASG-1S has no problem delivering a punch strong
enough to satisfy most bass heads without completely overshadowing other details.
The bass on the ASG-1S does a real good job reproducing the decay of bass
guitars and drums. Subbass reproduction is really prominent on the ASG-1S and
really lives up the Aurisonics slogan “Rattle your teeth bass”.
Final Thoughts
The ASG-1S is extremely an elegant pair of IEM and the tuning
offer a significant improvement compared to the ASG-1.1 while performing the
same task. Of course the question that arises whether or not the ASG-1S is
worth the extra $200. Objectively speaking, the aesthetic treatment itself is
worth $200 if we were to look at the aesthetics so the special tuning is an
added plus but the extra $200 is also enough to let someone buy an ASG-2 which
makes the decision much harder to make. Currently I do not have an ASG-2 to
make a sound comparison with but I will update this when I do.
Dunu DN-16 "Hepheas"
Pros
- Extremely fun bass oriented sound signature
- Impacting sub bass
- Treble and mids are surprisingly prominent
- Despite the bass boost the DN-16 still manage to
have a fairly balanced sound signature
- Build is amazing on these IEM
- Loads of accessories
Cons
- Mids are occasionally shadowed and veiled by
- Speed of treble seems to be a struggle and tends
to grain up
General Overview
The target audience of the Dunu DN-16 “Hephaes” is the
mainstream consumer base or more specifically, those who prefer the Beats sound
signature. They sound best when used with bass reliant genres. The first thing
I noticed about the DN-16’s was the
amazing looks and the surprising weight of the IEM. Upon putting them on, the
first thing I noticed was the overwhelming bass presence utilizing a patented
Power Bass System.
Build
The build of the DN-16 is definitely among the best I have
seen in the $100 range. The first thing I noticed about the DN-16 is the
distinct weight they had. According to Dunu the housing is made out of titanium,
which give the DN-16 a real solid build and quality feel. Of course, the
aesthetics are a nice touch as well.
Accessories
Dunu has always been amazing accessory wise and the DN-16
does not disappoint coming with an array of accessories I only find in the
$200+ range. (add list of accessories)
Overall Sound
Bass is the name of the game with the DN-16. Upon plugging
them in they take any trace of sub-bass in the track and expresses it as a
prominent THUMP. On first impressions I would have said the DN-16’s sound
signature was fairly similar to the Beats sound signature seeing how they both
emphasize bass and tend to color the mids, but now I think they’re completely
different in the sense that the DN-16 focus on sub-bass rather then bass quantity?
Though the effect on the midrange and treble is rather apparent.
Treble
Treble is definitely the weakest link in the DN-16’s sound
and is best used with genres that don’t place too much emphasis on treble. I found the treble lacking the smooth fluent
sound of other headphones near its price range and generally sound sandy or
grainy with most of the tracks I used them with. The response speed of the
DN-16’s treble tends to struggle with fast tracks and meld into a mass of harsh
rasps.
Mids
Immediately after plugging in the DN-16’s I noticed a
distinct veil where the mids were distorted because of the emphasis applied to
the bass. After at least 50 hours of use, the DN-16 was really hit or miss when
it came to the midrange. With half of the tracks I used with the DN-16, I found
that they had clear, but coloured, mids that are backed by the pounding bass of
the IEM. With other tracks, the mids and vocals were in a constant power
struggle with the bass for forward presentation. This made the midrange and
bass appear to originate from the same source and plain and made the sound feel
flat and rather stuffed up. Overall the mids are fairly well presented and,
more often then not, provide a fairly pleasant experience to the listener but
when used with the wrong tracks, everything becomes a jumbled mess.
Bass
Bass was the name of the game for the DN-16 and it would be
an understatement if I said the basshead side of me was amused. If bass
quantity were the most important aspect in an IEM, the DN-16 would beat the
competition with ease., I think the only way you can get better bass quantity
is by attaching a subwoofer to your head. I found the DN-16 really excelled
with most mainstream genres that really depend on bass such as trance, hip hop
or pop but tends to struggle with acoustic bass because the bass decay tends to
distort the reproduction of a bass guitar.
Soundstage and Overall Presentation
The soundstage of the DN-16 was rather typical when compared
to other IEM’s in its price range but I found the frequency response would
continuously disrupt the presentation of the DN-16. Continuing on the issue
that I touched upon on the midrange section, I found the occasional power
struggle between the bass to give the IEM a really flat sound.
Final Thoughts
The Dunu DN-16 “Hepheas” was a really fun experience and it
was a rather nice retreat from the usual audiophile signature that I’m used to
reviewing. The DN-16 were designed for use with mainstream genres and its
tuning reflects that. The DN-16 tend to target mainstream consumers rather then
the critical listeners who care about neutrality therefore I don’t find it in
the same league as other neutral IEM such as the Hifiman RE-0 or the Shure SE 215,
as they target different audiences. When compared with similar IEM such as the Beats
Tour, the DN-16 becomes a real competitor.
Announcing the Aurisonics ASG-1S
So something really special just arrived today! The new Aurisonics ASG-1S signature series! These are the same as the ASG-1 except they have polished shells and chrome plates.
If everyone remembers a while back it was announced that Aurisonics would be creating 10 limited run ASG-1S that are handmade and tuned by Dale, this is no longer the case. They are now a regular product of Aurisonics and will cost $499.99.
Apparently, mine are the first ones created (so serial number 0001) and is missing the otterbox. I would like to inform everyone that these DO NOT sound like the ASG-1. They have, what Dale calls, "signature series tuning".

Aurisonics AS-2 Prototype Review
 |
| Copyright 2012 Aurisonics, Inc. |
Introduction
A few months ago I decided to get myself a pair of Custom In-Ear Monitors. This was before I joined Headphones for Dummies and before I knew jr.kong. I decided to buy the AS-1's as I liked the ideas behind them very much, but Dale Lott of Aurisonics surprised me and gave me a sneak preview before anyone else of what would come. The AS-2's I received are considered prototypes. I will go back and forth between calling them prototypes and regular AS-2's as I see fit due to what I know has changed or not since I received my pair. But please understand that they are very much indeed prototypes, as they were in my possession before the official release and also has one added and one missing component.Pros
- Stellar audio reproduction
- Custom molded for a perfect fit based on ear impressions
- With a perfect fit you hardly notice wearing them
- Many different options for customization ensure you have a personalized product tailored to your aesthetic pleasure
Cons
- Price doesn't scream, "throw me around and don't worry about losing me"
- Added price of audiologist appointment or time to do it yourself with provided impressions kit
- Bad impressions will give a bad fit and hurt your ears
- Some hiss does exist when around items with strong RF signals or an electromagnetic field near the source when using them. It's not always, it's not even consistent, but it does happen, it comes with the territory of balanced armatures. It's nothing that would cause anyone to complain that they are unusable. It's hardly noticeable, but if you're trying to hear it you'll hear it at some point.
A Small Warning
This product was developed mainly for those people in the music
profession. That is not a bad thing, but it is definitely something to remember
as some other companies make products meant for consumers that are used by
artists, but these have even more power and care taken to them and
are stated to be for professional use only. I feel it is important to inform
everyone that you should always listen at safe levels which is the case with
all products, but especially ones that were not designed for consumers.
Features Breakdown
In this section I am going to break down what I think of all the features that appeared on the main page for Aurisonics when they announced the features and where the AS-2's would be launched.
- 15mm Dynamic Driver
- Next Generation Dual Tweeters
- The AS-2's feature three sound components, one 15mm Dynamic Driver and two "Next Generation" Balanced Armature tweeters. The combination of which is spectacular to behold.
- Adjustable Bass Porting - For those of you who love your bass, and it's easy to see why with the AS-2's, this port will allow you to adjust the bass levels, but please be advised to practice extreme caution as these are made for music professionals, not for consumers. I wouldn't be surprised if you can rattle your head so much with the AS-2's that you hurt yourself. I've definitely pushed the AS-2's a bit hard on the bass and they never disappoint, but I still advise extreme caution in doing such things.
- "Hyper-Coating" Comfort Tips - This is the feature I have yet to receive. I will be sending in my AS-2's for this treatment to be done. From what I understand it is a special compound developed that will help cling to your ear canal from your body heat and help the AS-2's stay in even better. I have had no problems without this, but I am curious to see what it can add to my experience and will report back later.
- Recessed Connectors - Aimed at allowing for more durability and longevity of your In-Ear Monitors, the recessed connectors may be seen as a plus or a minus depending on your needs and if you want aftermarket replacement cables, as not all of them support recessed connectors.
Looks
Comfort
The comfort level of the AS-2's is a positive thing. Since they are custom made to impressions I sent in, they hardly feel like I am wearing anything at all. I have had many listening sessions that lasted only a few minutes, and many more than turned out to be hours. This is good for those of you that are musicians and for those that are not. The ability to not notice any fatigue or discomfort from a pair of headphones, or in this case In-Ear Monitors, is important and welcomed. Music professionals should have no fears about being able to use this on stage during a long set, or just for long mixing or listening sessions.
Accessories & Packaging
Similar to all other Aurisonics In-Ear Monitors, the AS-2's come with a Otterbox. Custom molded In-Ear Monitors come with the Otterbox 2000 to be precise.
Besides that, the AS-2's came with a little satchel to store the AS-2's in and a tool to clean up the area that the sound comes from, since it will build up with ear wax and need to be cleaned off every once in a while. All in all, nothing too great, but not lacking. I would have loved to see an included microfiber cloth to wipe off finger prints from the chrome panels on the AS-2's after insertion to my ears, but being that they do not need much more maintenance than that, a case to keep them safe and a portable case for on the go along with the cleaner tool was more than adequate. After talking with Aurisonics they are including a polishing cloth with plated versions of the AS-2.

Sound
The overall sound signature of the AS-2's is flat. Each of the three normal divisions of the frequencies are equally balanced with each other and this makes for a fun experience. The important thing about the AS-2's is that no matter how much I have tried boosting any single part of the highs, mids, or bass the overall sound from the rest of them is still superb and unaffected. Each section is well contained and little to no leakage between them means if you like it more bass heavy, go right ahead, you will still hear everything crystal clear. A song by Bassnectar called "Ping Pong" samples a ping pong ball bouncing around. The 3D imaging is amazing on the AS-2's, but if you turn up the bass levels you will still hear the clearness of the ball bouncing around like it was a leaky faucet dripping a drop of water in an otherwise silent room.
Treble
This is the area in which those two tweeters come into play. The highs are interesting on the AS-2's. It's this part of the AS-2's that I guess one would think the tweeters are standalone and separate from the 15mm dynamic driver in them, but to my understanding this is not the case. The balanced armatures in the AS-2 seem to compliment the dynamic driver to ensure that you are not just able to hear the highs, but also hear them well and enjoy them equally. Listening to music with really high notes hit by a vocalist is spine chilling. It's a great feeling to have something that hits hard as needed in the bass and still delivers like this in the treble space.
Midrange
The midrange of the AS-2's are lush. They are warm and inviting to you as a listener. I find the midrange to be perfectly tuned for the other frequencies to complement them. Similar to the treble, the midrange is quite airy making the two seamlessly co-exist in a unity of spaciousness and yet similar sound qualities. The midrange is airy and textured. It really makes you feel like you are there as you hear the pluck of the guitar in front of you. the tweeters used for treble levels mean the midrange is not overpowering the trebles at all. The midrange feels like so much of the rest of the AS-2's, which is a product that you can tell took some hard work and care to make and perfect.
Lows/Bass
It's something I have been talking throughout lots of sections of the review and rightfully so. It's amazing how the 15mm driver inside this In-Ear Monitor performs so well with all the frequencies and realize that it also handles the bass at the very same time. The bass is crisp and clean. In the past with my headphones that I have had that were considered Basshead headphones, with great bass, I never had anything like these. On tracks I previously thought were mastered poorly because it's bass did not produce much rumble or have much depth to it. With the AS-2's, the bass still does not lack it's clarity and texture when testing with those tracks. The bass goes well below my previous headphones, the Denon AH-D2000's that have quite a history of Basshead territory in the audio hobbyist community. I highly recommend anyone worried about finding something that'll give them that bass craving they have but fear losing the rest of the frequencies or even just think it'll be too heavy. It's a bit hard to get a handle of, but I can't think of any other way than to say, the AS-2's will perform as close to how the master engineer for the song intended it to sound. If the song is meant to have light bass, that's how the AS-2's play it. Yet at the same time, if the next song calls for lots and lots of bass, it'll deliver that as well, nice and clean, without any change of settings. In actuality, that's how every headphone or In Ear Monitor should be, but I have never found one that does on such a consistent basis until the AS-2's came along.
Soundstage and other qualities
This is one of those things that one feels the AS-2's were made for. I got the AS-2's while I was going through finals at school and used them at first while studying. I was in the library one day and the track I listened to had a sample of someone clapping very far away. I instantly started looking to my right and their was not anyone their for about 20 feet, yet I could have sworn the clap came from that first person. I listened to the track again and realized it was something in the music, but it definitely made me know I had something special. I have been enjoying very much the use of live music recordings to see how large the soundstage really is. I've pushed it to where using stadium concert recordings you'd swear you were actually there. You can tell exactly where the band is positioned and if a member has moved around on stage. You can hear the slight nuances of the fans and figure out exactly where the microphone must have been if you look at a map of the stadium it was recorded in. The instrument separation is unreal sometimes in how well you can just try to only listen to the pianist or any other instrument and just completely get lost in only hearing that instrument as it's perfectly clear and is not being blurred by any of the other instruments during the song.
To EQ or Not to EQ
For the AS-2's, the need to EQ like with the ASG-1's reviewed previously on the blog is not existent. I have tried it and it does not do the job like it should. The balance of the AS-2's already is amazing. The use of equalizers is meant to fix or account for the sound qualities of a less capable headphone. An equalizer for bass boost would look to help give that extra attention to the bass frequencies since they are not getting enough power to the headphone or are not as efficient at playing those frequencies as it is with other frequencies. The AS-2's do not have that. Every section of the frequencies that make up the spectrum that humans can hear is accounted for and level with each other.
Final Thoughts and Recommendations
The customer experience provided by Aurisonics is a treat to encounter. They are responsive and will work with you. This product is a gem to behold. Within moments of use it is obvious the amount of work and dedication that went into developing it and the things it is capable of are astonishing. If you are able to afford the price and are looking for a custom In-Ear Monitor, you won't go wrong no matter who you are. Whether you are a Basshead, love the sound of amazing vocals, or just enjoy music with no preference for anything to be particularly strong in any which way, the Aurisonics AS-2's are something to consider as they have lots to offer for anyone with a love of music.
