Quality:
seemed as reported good in workmanship, the clattering noise of cheap plastic made me but a bit put off. Even the loading mechanism sounds cheap to (when you insert the headphones into the charging cradle), but at this price you can not ask for much more at ease. That's OK so you can not really complain about anything in particular.
Coverage:
In the building through 3 walls even at 40m distance still good, sometimes noise at certain angles to the sender, but not annoying. Reach so very good. Unfortunately, despite noise reduction exactly that: noise. Unfortunately, from time to radio stations in your ear, then you have to choose another one of 3 possible frequencies at the transmitter and "connect" the new headphones.
Comfort:
with a large head very well. But I can understand that he does not fit any because I had to leave very little - much less than other headphones. He wears then very well, without pressure. Jogging can you no longer, for he is not even thought of. The mussels go over greater Wascherl me it would possibly become too warm, if I had tried it longer ... but this it did not come.
Service:
The volume control is too small, the operation somehow tricky, but in itself it is good to find. The on / off switch is easy to operate, the key to connect to the station I have to look again and again, one also needs hardly.
Sound:
That was the reason for the decision to send him back. Aside from the noise, even if you're sitting right next to the station - is more than 300 reviews really anyone manipulating the sounds noticed? Whether if untwisted via laptop, stereo or headphone amp before sending or on headphones or on both sides: hear soft sounds are amplified, thus the noise is further lifted as soon as the song is loud, everything is adjusted again in the volume, similar to a compressor but much stronger than the radio. This is for listening to music simply an absurdity. No miracle for 65 euros are indeed expected, but he was able to sound not even in the same league play with a wired 25 euros headphones.
Conclusion:
Clear, 65 Euro for a wireless headset that can not be so much. Sony but would not be expected to bring a device with though not underground bad but very very lean acoustics on the market. It's my first ordered at Amazon products must really go back.
