Has then also true in my case. I can thing as listening to music on Macbook or iPad just use such calls with your Android phone. If you want to use when watching movies the thing, however, you must remember that there is through the digital encoding of the audio signal delay; ie the sound comes too late compared to the image. With a suitable software player (eg VLC) can be offset (approx -450 ms with me) indeed correct, in many other applications such as live TV with a TV-Stick in the PC / Mac or Internet streams has one lack of adjustment on the setter rather bad cards.
Sonically, the level to what you also get with just any compact headphone cable for 20-40. Since you should have no illusions, the charge goes for Bluetooth on it. If you listen to what it otherwise at supra-aural headphones are small (eg the right popular models of AKG), then this is matched comparatively neutral. So not that bass-it-crashes. For me, that's fine. Who needs more thud, just needs to try the equalizer of his player.
The Bluetooth transmission works very well, also bridges a wall (but only one) and the gain is virtually noise-free. Not with any Bluetooth-setter, however, you get the same sound quality. The (re-) compression of the audio signal - usually with the SBC codec - does not take place at each transmitter at the highest possible bit rate / quality. For the headset can not, taking just what he gets leaked. If supported by the transmitter, can be streamed in AAC audio instead of SBC, also can handle the headphones. However, Direct MP3 streaming is not implemented to my knowledge.
To prepare the Bluetooth pairing (Paring) I had to actually take a look in the manual throw: with switched off handset hold Power button more than 7 seconds and the headset is for other devices "visible". Complexity, it is not, you just have to know.
The Bluetooth pairing can also be automated via NFC ("Near Field Communication"), but of course requires a so-equipped mobile phone / tablet. Here, the mobile phone then reads the Bluetooth identifier of the headphones by simply stringing together hold the two devices and then builds the connection to self, without the further need to do something. At least in theory. I have only one device with NFC and since then had to be re-started a Sony app which then scans for NFC and somehow I do not get it, no, if it's really so much easier than in the Bluetooth settings on "Connect" to tap?
The operation is otherwise simple: in addition to the already mentioned power button, there is still a high / low volume rocker ", a clever rocker and push switches for" forward / backward / Play / Pause "and a button for" Accept call ". Another switch enables / disables the NFC-supported coupling. All this is no riddle.
Loading via USB, with the supplied cable is a widespread (but very short) cable with micro USB plug. Shop do not have to very often, because if something is really extraordinary, it's the long operating and standby times. Supposedly, it promises the advertising, the headphones can remain around 30 days in standby and play 40 hours music. Even if it in practice, only half was to be achieved, that would be even remarkably well.
