A while ago I bought a plantronics headset. It broke within the first two weeks and got a replacement. Today they broke again with the same issue the right speaker went out and cuts on and off like a short in the cord. I opened up the headset and looked inside the speaker and all the solder connections were fine. Just the cord shorted somewhere. I would not suggest buying plantronics as they are garbage now. My SENNHEISER PC151 lasted me 2 years. I'm going to buy another pair of these as they are a great price right now.
