SBH-20 + MDR-NC31EM + Xperia Z3Compact

Background / reason to buy:
Due to my new mobile phone Xperia Z3Compact I wanted my previous iPhone headphones no longer use and have therefore bought the MDR-NC31M of Sony, I'm much by bus and train go and the background noise would have minimized. So far so good, everything is perfect. However, I realized relatively quickly that these headphones have no "remote control function", so I eg. High / low and forward / backward etc. always had to make the cell phone, which was annoying.
Therefore I have to Bluetooth headphones (ear it had to be) around and had the first Plantronics BackBeat Fit, which are really awesome. However, I realized very quickly that always moved up when wearing jackets this the rear bracket so that it was unfortunately unpleasant. Otherwise, these are really highly recommended!
Without further ado, read several reviews, including here also, and so I bought the SBH-20 in order to continue to use my previous headset can, however, extended by the lack of remote control functions.

For product:
Small and portable, perhaps too small for thicker fingers, but this is purely subjective.
The pressure points of the functions are found relatively quickly, but you have it, of course, often try to become a feel for it.
Quick charge and coupled via NFC by mobile phone. Went so far as simple, as long as you have (n) before reading the manual briefly. Therefore, here the tip: the coupling on the lower symbol (front, below Play / Pause) Delete briefly, then it will come :-)
All functions fold properly and my headphones are now somehow maximum louder adjust because I asked the phone volume on the center front of the paddocks.

The sound itself is really great in this combination. Now I have even stronger bass than I had before without Bluetooth, for whatever reason. Of course, the headphones work well NoiseCancelling unrestricted, which also surprised me positively.
Disconnections or even noise I could discover in any song (Pop, Wave, Klassic, ballads - different bit rates, tried everything).

Nice gimmick: Of course I can again put the headphones directly into the phone and SBH-20 only use as a remote control module via Bluetooth, everything works perfectly, including all functions.. At least for me with the Z3Compact.

Only with videos with the VLC player the signal lags minimally behind. Perhaps there is still a setting or someone has a tip for me, but where it is not quite as bad. It however noted already minimal.

The package itself can be found next to the Quick Reference Guide have a really very short charging cable, a separate power connector for USB connection and of course easy Sony headphones themselves. Whether they are good, I can not judge because I initially do not use it. As a replacement certainly not bad, I think at least.

Priced I again "cheaper" get this thanks to a price comparison portal, as provided herein.

Conclusion:
Thanks to all previous recessions, because I have this led to buy what I definitely do not regret. Super great product with a fair price / performance ratio. For this reason, I can only express a recommendation.
