The highs which are normally quite bright with the TWFK are a lot smoother on the R-50 yet still extends very well with great detail. They still have the analytical sound that other TWFK drivers have just presented in a smoother way, you still get all the micro detail. Mids are equally smooth and detailed and are centered right in the middle as they should be on a balanced IEM like the R-50. The bass is really good and I can't believe how much this little driver can pump out. It has excellent punch and can go quite deep with great texture and decay for a balanced armature. Another strong suit is the soundstage that is larger than avg and is very well rounded, also has great separation and imaging. These are the best bang for buck pair of IEM's I've ever heard and I've heard a lot.
For a new company to come out with something this good on their first try is outstanding and anyone looking for a very detailed BA with a smoother presentation you'd be hard pressed to find one much better than the R-50 at this price point or even at $300.
Its been over a month and a half and these are still my favorite IEM I own. They're nicely balanced with a touch of warmth and great detail. When I use them with my Sony player and my E6 amp they sound amazing with a fuller sound and larger soundstage. The right tips make a big difference as well, I found that my Atrio MG7 dual flange and the foam tips make the R-50 shine with better isolation and sound. Also the Sony Hybrids and any of the Etymotic tips work really well with them. The build quality and fit on these are great, I've ran, worked out and even played basketball with them and they work great never even had to adjust them because of them slipping out. They have a little bit of micro-phonics but nothing that gets to loud or annoying. These truly are one of the best IEM's I've heard and for what they cost its an absolute steal so if your reading this just buy them.
I've now had the R-50 for a little over 4 months and they're still one of my top 2 IEM's I own and one of the best I've heard under $300. Since I finally got a FiiO E11 portable amp they have opened up the R-50 nicely making them sound larger with a fuller sound. It doesn't change the sound signature at all just enhances them to there full potential. Its gives the bass more impact and a bit more depth along with better width and height in the soundstage. There still intact with no damage thought the cable has a few spots where it unraveled a bit but not to bad and doesn't affect the sound at all. Still loving these bad boys and I'm so glad I stumbled upon them one day because who knows when someone on Head Fi would have finally found out about them.

MY IEM HISTORY:
I owned different "in-ears" ranging from $10 (UE100) to $100 (Shure S4) and thought that there is no sense to spend more money on earphones. Eventually I decided to try Balanced Armature-based earphones and bought UE Superfi 3i (based on ancient single BA driver with almost no bass response) which, not surprisingly, were below my expectations. Next ones were Shure SE215 which had a developed sound stage and larger sound range. R-50's were my next purchase. Just to let you know, the sound is better than Westone UM2 (my best friend was kind enough to give them to me for comparison).
Westone UM2 - $250-$300
Westone UM2 Clear Earphones
DIRECT COMPETITORS (USING SAME Knowles TWFK drivers but different sound dumpers):
EXS X20 - $200
VSonic GR01 - $205 - $250
VSonic GR01 Pro balanced iron drive noise Isolation Earphones Earbuds IEMs with 15 eartips
1) Small driver enclosures - fit well inside ears.
2) Sturdy and Flexible ear hooks - slightly softer than I would want, but still nice and, after 2 months of use, they seems like brand new. I expect these to last for quiet some time.
3) Tangle-free cord.
4) SOUND is FANTASTIC: Balanced highs and mids with distinguished bass make these universal earphones.
1) YOU MUST USE a high-quality player to drive enough bass out of these earphones. When I connect them to my YAMAHA A/V receiver, the sound is just great. I have to use EQ with "Small Speakers" setting to mimic the above mentioned sound while using my iPhone 4S. Otherwise the bass is lacking since they have pretty high resistance (31 ohm, according to specs written on the box)
2) As mentioned by another reviewer, change the eartips to triple-flange ones to get the best performance.
I use Mens Size - Earphones Plus Brand, Tri-Level, Replacement Ear Cushions, Earbuds for Sound Isolating Earphones-2 Pair but these fit slightly loose on earphone sound canal.
3) Over-the-ears with "braided" cords are a bit messy to "unfold" (sorry for my limited English)
4) The cord is thin and not very durable (check the update in the bottom of the review)
P.S.: When I, after continuous listening throughout a month, switched back to my good old Sennheiser CX400-II Precision, I realized how cheap they sound in comparison with R-50s. All the other earphones I currently have will be used-up throughout the time in GYM only (that's the only place where I do not care about how clear my earphones sound).
P.S.S.: If you have any questions, requests or can find any corrections in my review - please feel free to ask/correct me. It will be appreciated.
It's been precisely 4 months since i started using these earphones, and today my left earphone stopped working - one of the three cord threads detached near the 3.5mm plug. I have expected something of this nature since the cords are super thin. Still I am disappointed because I expected a $120 earphones to last at least a year with my light use. My previous Sennheiser CX400-II lasted well over a year.
Downside: you have to send it back (with ALL the original parts in original box) to be fixed. In any case, you have to cover the return shipping which for R-50 is $25.
BUT: If you know how to use iron solder, you can get a 3.5mm plug replacement and fix the earphones saving you time and money.
OR: You can re-shell your earphones at, say, Kozee ($120 for custom molds + extra if you want additional balanced armatures installed).
The R50s proved excellent precision of sound with a neutral presentation. I find them very accurate in the low end. There is no "enhancement" as with the others mentioned. If the bass is there you hear it all they down to the very low frequencies. If it isn't there the buds don't add it. Acoustic guitar is a joy just for the clarity of the notes. Hard rock has punch. Classical reveals subtleties. The bad news, if it is a bad recording these buds do nothing to help it.
For the sound quality these buds have the price is my money well spent.
