I ordered these headphones thinking they would be a nice replacement for my Sennheiser hd202's that just went out. I couldn't be more wrong; as soon as I plugged these in, I quickly noticed that only the left side was working. I tried everything to see if I could get it to work, (maybe theres a short in the cord?), but to no avail. I don't think I would have very good luck attempting to get these replaced either. Do yourself a favor, DON'T BUY THESE HEADPHONES.
