I am really interested in it too. It is really difficult to turn every single headphones to wireless. I recently saw a gadget named btunes on kickstarter. It applies to those headphones with standard 3.5mm or 2.5mm jack on. It is great, isn't it? At least someone think about it and try to make...

 good luck

This is really helpful , actually, I am thinking of HP50, how is the sound on your opinion? And you are absolutely right, I don't have big/large ears. 

Classical music. Closed is better. That is right, $300 is my limit. Thanks a lot, I will take a look at that site.

Thanks,   Some classic, some pop.   Crystal clear and decent bass.   I'd like to try some different cables to see the difference or any impacts.   Sorry, I have no idea how to mod. 

I am looking for mid-high end, around ear headphones and cable is detachable. There should be a standard 3.5 or 2.5 mm jack. It seems Sennheiser Momentum is a good choice. Any other recommendations?

Yes, I think so except AAC NFC.

Sonic electronix sell ath m50+nvx ex10 at 149.99, is it a good deal?

Is it with aptx? As you can see from pics, they are using different Pcba, but not sure about the driver. Pls post the comparison when you get them.

Yes, what matters to sq is supposed to be aptx, actually, bt4, 3 or even 2.1 should have no sq difference. 4=3+low energy=2.1+high speed+low energy

Thks, Pal. :)

I am wondering whether it will sound better if connecting to aptX enabled devices? Btw I noticed that there is no NC, will it still be good to use during travel? And what about the leak? :)

Frequency response can not tell everything, I am curious about the sound quality difference since they are bluetooth headphones with aptX and also, they provide detachable cable. BTW, the impedance is 64 ohm, is it helpful to control the treble? let's see.

it is hard to tell now, somehow, aptx codec make the difference quite small w/i or w/o cable (as the ads) like digital vs analog, which is better, 

From my point of view, Parrot zik is high-tech consumer electronic product UE9000 is bluetooth headphones   Hope there are some headphones to combine all the good stuffs together, great design, state of art technology (aac, aptX, nfc, touch) and most important great sound.

I have similar criteria, a. wireless (aptx codec at least) or detachable cable, b. easy to carry, c. mainly use with samsung S3 (so it'd better with nfc) d. i only hv 150 budgets.   This one seems quite match, http://www.youtube.com/watch?v=L2hYIDFU7FI   I am not brand lover, but VOXOA...

I am really interested to this pair of headphones (bt 4.0, nfc, aptX)   But, 8 speakers, seriously? i doubt if it will damage my hearing. What kind of devices do you connect to these headphones? pc, phone etc.? Does aptX really work to deliver high quality streaming sound? anyone try the nfc?
