Summary: Absolutely brilliant headphones! Bought for VOIP, but surprisingly good sound for listening to music also. The jack pins also good. I've noticed that sometimes headphones on jack pins have inadequate volume, and thought it was my computer's fault. But these are excellent.
Summary: Great features, amazing quality. long cable which won't tie you to your desk, swivel mic switches the mic on on off easily whilst the other ear side has a neat discreate volume control. Once again Sennheiser have got their product perfect and a great price.
