In 25 yrs playing music, shure have never let me down. Until now. These earphones were great, for 3 mths. As were another shure set I bought for my bandmate which will be my second ever review. The left side stopped working, quickly followed by the right. I bought another cable for 30 quid as I was sure that was the problem. Now I'm an extra 30 quid down with an expensive pair of, what can only be used as, earplugs. I purchased 6 pairs of cheap earphones (so i never get caught short in a gig again)that, in total, cost less than these. They are working perfectly. I highly recommend you do the same
