1) Microphone. The headset does not have any noise reduction system, the sensitivity of the microphone itself is very weak, so that you can be heard clearly, you need to take the cord near the right earpiece, where the remote control has buttons and a microphone hole, and bring it close to your mouth, even in a quiet place, and this is precisely the hardware problem of this device, since I am equally hard to hear both during a normal telephone conversation in a quiet room and in PSN networks, even if you set the sensitivity to the fifth level of the scale in the microphone settings of the console, the result is zero, and it has nothing to do with the speed of the Internet (speed is more than 100 megabits / sec.);
2) The remote with buttons is a quiet horror. Feeling the middle on / off button (it's the same key for answering an incoming call) is not real, you have to take out the right earpiece and see what exactly you are pressing;
3) The operating time of the headset differs from the declared one (when listening to music at full volume, the headset "beeps" about its imminent discharge already after three and a half hours of continuous listening), in the telephone conversation mode, there are not enough words in this World in order to speak without silent as much as 8 hours in a row, charging takes about an hour, with a current of 1A.5 volts;
3) The fastening clip: it broke a year later (I showed the place of the break in the photo on purpose) of very rare use (I actually used the headset ten times for the whole year), and the break happened without my participation, put it in a case with a whole clip, and took it out, the clip itself fell apart inside the case. Moreover, this is not a matter of my "crooked" fingers, but in the bad plastic of the clip, I have friends who own this particular headset, like me, with a similar breakdown of the clip in this place (it's a shame, the presentation is damaged).
4) During charging, the headset turns off tightly, you can’t use it, in the manner of headsets (even the most budget ones) from Sony, which continue to function normally while recharging, leaving you chatting online on PSN, Skype and others, and do not turn off , like this product, sadly burning with a white charging indication .
