I had an entirely different experience. I had a similarly priced Sennheiser headset and they were great. I had the exact same issue as well with headset's left speaker stopped working couple of weeks after my warranty expired. I called them up and they said they cannot do anything and I will have to a buy a new one. In the end, it turns out that a connection got loose so I fixed it myself. But I was slightly disappointed with the reaction from their customer service.
