Review - DX160 iE
Disclaimer
Before I start I need to mention that the following are my personal opinions based on what I can only describe as a 'novice level' experience with IEMs.
In my youth I had experience with a small number of ear buds and for many years have simply ingnored earbuds and IEMs altogether in my persuit of quality headphones.
Only about a week before receiving the DX 160 iE, did I by chance acquire a CX300 II, so fortunately I had some time to get used to the sound of low-end IEMs again before writing this review.

Packaging
I won't linger on this, but I will say it was better than I expected.
Build Quality
Overall I am impressed with the qualtiy and finish of the materials.
The machined metal housing is very pretty and has an excellent finish.
I am a little concerned that the outer circle is a plastic that may scratch too easily over time, but it has a nice slightly matt/pearlescent
finish that I like the look of.
The flat cable has a slighty rubbery feel to the material. This works well as an anti-tangle measure; a feature I have experienced works
well too with my Sennheiser Momentum cable.
My only concern is that there isn't enough strain relief or support around cable termination points.
There is plenty of strain relief on entry to the IEMs themselves, but at the plug-end of the IEM-cable, the entry into the plug seems a little too
sudden considering two cables meet at this point.
As the extension cable only has to deal with 1 cable terminating at each point, the build seems more than sufficient.
The clip certainly isn't the highlight of the product, but it works well and looks good.
Design & Aesthetics
The flat cable really does help keep things tangle free. I've had experience with flat cables before, and these performed even better than
others due to higher flexibility and light weight.
I really like how the extension cable terminates at 45 degress. It's a surprisingly good compromise between a 90 degree and
perpendicular plug and makes is much easier to unplug than a 90 degree plug.
The IEMs are a little big. They do stick out of my ears a fair bit, and due to my ear-canal shape, they also point slightly downwards; this
means that they look like they're about to fall out and makes them look sort of 'sad'.
I think it's great that there's a physical mark (a small dot) on the inner right IEM to make it easy to locate the right side IEM in the dark
or for the visually impaired, however I would have preferred a more obvious visual key other than a small 'R', indented into the rubber, as
I'm more accustomed to the common industry practice of a small red ring or marker.
The extension cable feature I found totally unnecessary. I can see how this would be great if you just clip your ipod nano (or similar device)
to the top of your shirt, or under your shirt collar or something. However the only thing it did for me is add more weight to the cable which
forced me to use the clip. This quickly became a small part of the routine, but I personally didn't gain anything from it.
Unfortunately cable microphonics were quite pronounced. I've heard worse, but they were pretty bad. This made me want to walk slower
so the cable would stop waving around so dramatically due to the extra weight of the extension cable plug.
I have quite small ears and apparently quite small ear canals too. I tried out the smallest varieties of silicone tips provided, but found that
they didn't offer any improvement to comfort and isolation, and only the very smallest fit properly while providing a good bass-seal,
although they were a little loose.
So I've auditioned these almost exclusively with the Comply T400 tips provided. These gave the best bass seal, massively superior
isolation (over 90% of sound is blocked out compared to the silicone tip 50-60%) and best sound quality.
I think for my needs, size T300 would be a better match for my ear canal size, but due to the greater tolerances memory foam tips
offer, I was able to use these T400 tips without much trouble.
Case
Not much to say here, but despite the zip which I thought would make for a slightly more time-wasting design, I was quite happy with this.
I didn't use it, but there is a small pocket in the lid, I assume for the splitter, or extension cable storage.
Sound
Disclaimer - my reference of neutrality for an open headphone is the HE-500.
My reference for a closed-back headphone that is close-to-neutral (0-2000hz) is the Sennheiser Momentum.
Silicone tips vs. Comply T400 tips:
Firstly I would like to say how glad I am these came with the Comply tips. My entire sound experience with these would have suffered
greatly without them, as none of the silicone tips provided equal comfort, isolation or sound quality.
Bass
With silicone tips, the slight hump in mid-low bass is more pronounced and slightly loose.
With Comply tips the hump was still present but tighter. That's all I'm going to say about difference in tips.
Overall I was very impressed with the bass. The extension and texture are more than I would expect from a full-size headphone at this
price point.
There is however a slight mid bass hump that bloats radically on some electronic recordings, but this is limited to a very small
frequency range and therefore doesn't occur often.
Mids
This was the only thing in the whole package that really made me uncomfortable for a few days. I really enjoy neutral, rich mids, but
I found that the upper mids were emphasized. This seemed to glare midrange detail but left me wanting when it came to vocals,
of which both male and female sounded thin and slightly distant.
It took a few days to get used to this, but I still don't know how I feel about it.
The resolution however is right on the money though. Very difficult to fault.
Treble
From my experience with the CX300 II I wasn't expecting anything spectacular from the treble. I was however pleasantly surprised to find
that the treble was present, detailed and even possessed a slight shimmer.
The treble does roll-off quite a bit, so I wanted more sparkle at times.
Subjective Observations
My biggest surprise was how good rock music in general sounds with these. Guitar tones are excellent and drums have a very rhythmic
tight sound. Some studio recordings that sound too analytical on most headphones actually sounded musical with these.
Queen's We Will Rock You and Led Zeppelin's studio recording of Moby Dick had perfect percussive crunch and the guitar solos were
fantastic in tone and texture.
I really enjoyed listening to Gorillaz with these. Often I don't pay so much attention to bass with other headphones, but these forced so
much texture and bass detail upon me that it was refreshing to hear it in a different way.
Soundstage, Air, Speed, Separation.
Compared to headphones the soundstage is very much in-the-head, but feels wider than anything else.
There is a sense of space and air to the sound, but no more than a half-decent closed-back headphone can offer.
The speed of these impressed me, and lends itself well to fast-paced multi-layered music.
Separation is excellent, and equal to or beyond the ability of headphones at this price.
Equalization
This is a quick EQ setting I made in Foobar that gives a closer to neutral presentation. There is absolutely no science here, just a
simple, quick picture of what sounds better to me.
The most notable resulting differences are: less bass hump, full mids, much improved vocals and treble sparkle.
Conclusions
For 100 euros,
these are worth it. *edit*
They offer more flexibility than closed-back portables in the same price bracket and in some ways they offer a better sound experience too.
I'm still not sure if the stock frequency response is something I could ever get used to and fully enjoy due to my own personal preference,
but with EQ the potential is there for a close-to-neutral-but-bassy sound that is detailed and tonally excellent.
Despite the
small niggles I have with the DX 160 iE, they provided me with a very intimate listening experience, removing my
attention from the bustle of my morning commute and replacing it with a well engineered mid/hi fidelity sound.
I
can honestly say I will miss these, and will be seeking an IEM replacement for my CX300II in the future.
I'd like to give a big 'Thank you' to Beyerdynamic for permitting me keep the test model, I won't need to seek a replacement ^_^
EDIT - 20.04.2014
It's not good news.
After another week with these IEM's I'm more confident in saying that I'm not sold on these.
The more I wear them, the more uncomfortable these get. I wish they were smaller and lighter.
The only good news I can offer is that the stock signature is more kind to the vocals of Michael Jackson, which are much less
affected by the slightly scooped mids. Overall I found his vocals the most enjoyable with these IEMs.
EDIT - 12.02.2015
It gets worse.
Now, the left side permanently suffers from driver flex.
The drivers are too thin, or flexible and I cringe every time I put them in my ears as I hear the plastic diaphragms crackling and changing shape.
Either I had some really bad luck, or there is a design problem, as my first review-sample had the same problem and my 2nd set is now also faulty.
I've had a few IEMs in the past, but never encountered such quick driver failure from simply inserting them in my ears.
Quite disappointed indeed.
