Comfortable and has good sound reproduction, both through the mike and the earpphones. If purchasing for Skype user might consider buying the video product as headsets are often included with the camera for just slightly more.
I bought two sets of the headphones for occational use. After a half a year, both of them developed problem of crossing the speaker. That is, I only hear one channel of the sound from both earphone speakers instead of different stereo sound for each speaker. This makes it useless.
