I did order for 2 head phones. One of them not work properly. Its Left Hand Side Speaker not working and I messaged same day about this. Seller replied me to send the video of the faulty item and I mailed them how to you understand the problem with video. At last i sent the video and there is no reply. I decided to initiate DISPUTE and """""DISPUTE """"""""on progress. More on additional feedback
It works perfectly fine, though you might need to go into the settings and change some stuff, because the microphone is really sensitive to background sounds.
