When they arrived I was delighted! Sound was good and easy to connect my iPhone via bluetooth and very stylish. I got them just before Christmas and this week when I went to use them there was just a loud 'clicking' noise all the time - worse when adjusting the remote and bluetooth playback was impossible. In short they're not working at all now - I have emailed Edifier's tech support and await any suggestions. But I honestly think it'll taking them back for a refund, or maybe a replacement pair that are more reliable. Maybe manufacturing quality is patchy? What a shame!
