When I ordered my BTR1 from Amazon UK (From a vendor from Scotland) last week, I didn't realise about the AAC issue, I am happy that the one that I received is indeed V2.0.

  Like you said, for the money, there is no comparison. The Ultrasone is 3-4x the price, T70P is doubled.

  It would be pretty hot if you do wear the Amperiors at the gym. Although, the double head band can keep them on your head pretty well during exercise. I just use a Philip bluetooth headphone in the gym, no cable to tangle! Sound quality is just so so, loads of bloated bass, but hey, that is...

  I think it is the other way round, if you are familiar with gun history. AK47 is the work horse of automatic rifles, you dump it into sea, mud, ice, pick it up and it will shoot, no jams; where as the original M16 is more accurate, deadly with the 5.56 rounds, but can jam pretty easily (not...

    I have the Oyaide cable, it has the same unequal L/R length so you will have to buy the HD-25 cable clamp.

I can see these headphones are really intended for the mass market, nor the professional market. DJs and studio professionals usually use whatever they are provided. Sound engineers usually go for the more proven and robust types of headphones. If they use Sennheiser, that will certainly be the...

    Cool, it's a nice can, isn't it? From my experience, adequately amping the 770/32 gives you huge difference. I tried it with my android phone when I first got it and started regretting somewhat for a few hours, but then when I plugged it in into my amp at home, it started to come alive...

Well, I am pretty happy with what the Omni is offering because I want a slightly more powerful output for my DT770 and my old HD590. I guess for you need, it is probably not the best solution. Honestly, I have no use of the microphone on the Omni and I do not usually use it for in-game...

I have just ordered the Omni, will post how it performs when it arrives next week.

I am also interested, between these two DAC/Amp. I can see both of them doing the same job, same price bracket as well, but Creative seems to be better in terms of amp power though. 

I am also interested in the Oxyide cable, I don't really know how much improvement it will provide, but it just looks cool.

Quote:   I have heard that there were a large batch of MH463 which have this problem in China. There are people who are selling these on TaoBao (Chinese version of Amazon/Ebay). Maybe my friend just so happened to have bought from one of these dealers. 

True, I think my friend might just got some sort of factory seconds from China. You know, anything can happen there. Their QC isn't exactly very good, especially for local sales. Anyway, better luck next time.
