I bought these headphones as an upgrade from my BD DT-770 Pro 80Ohm. The are better in all areas, except that the right can can't handle bass. As soon as there are low bass it just becomes a distortion.  Same thing happened to my DT 770 Pro 80 after 4 YEARS of usage, which is OK (I listen to bassy music, loud), but after only 1 week with these (at low volume level) they have become unusable for me.  I have returned them and got them back, with the same issue.    Although i love the Beyerdynamic sound, the build quality does not live up to...

I ordered my amp directly from Little Dot. No problem with the delivery and everything worked great. A con is that you get the same power cord no matter where you live, so for me it was just to put the power cable in the trash (I'll probably never move to where I might need it, and if I do, I'd probably lost it before I got there). The amp definately takes a while to burn in, but after it is, it is a very good amp. The power and the punch are excellent. I wouldn't recommend to low impedance headphones because it produces quite a bit of noise in...

DISCLAIMER: I've not listened more than 20 hours on them.   If these headphones doesn't tur water into wine during the next 80 hours of listening, I declare these headphones as the worst buy ever.    The first time listening to these headphones left me with an impression of bad bass and great vocal quality. My hope was that the bad bass would turn into at least acceptible levels after a while. This has not happened. Also, the vocals, to me, sound like played through a tin can.  Do not buy these unless you only listen to bad music.   ...

My firs uDAC (v1) fried because of manufacturing problems. I got version 2 as a replacement. What I like about it is the ease of installation and portability. I use it mainly at work where my options are a bit limited. For this purpose the form factor is excellent. What bugs me though is the un-dynamic sound that seems a bit distorted. In my opinion quite boring - I get a lot better sound (with the same headphones, Beyerdynampic DT770 Pro & Sennheiser HD200 tested) from my Sony Walkman A845 than from this DAC/Amp, even though the price is...
