Being very satisfied, so I picked the original ref and commissioned on Sunday.
Received letter from Max Tuesday (seller access2b). Quick!
I confirm, it's a Sony product license, and ca be verified live in the ears. Still amazed by the power low in these headphones. The sound is very balanced, even at high power. They do not hurt the ears and the microphone is also very good, my interlocutors have always heard me without echoes. My former MH410C have two years and have been abused (from the bottom of the bag, plugged / unplugged xx times a day ...) and did not move. In the end, a pair in the car and the other on me.
Sony If your phone is compatible, go for it! (Unless it appears Z1 ...)
Ps: for the record, the jack is right!
