Actually, I found the headphones very well, decent sound and comfortable fit. Also, the coupling to the PC and mobile phone worked fine. Unfortunately, the joy did not last long - after 2 months the socket is broken me yesterday from the headphones when plugging the charging cable - and that after only 2 times charge. Of course you can still use it with the jack, for me that was not the meaning and purpose of the thing. So now attracts a new headset with me - this time not from Philips, that's for sure.
