Perfect sound quality, both headphones and mic. It installs on Windows 7 no probs. Some Jabra for example won't install on Windows 7. The only downfall with these headphones is there is no padding at the top. If you ar bold, you are going to have a problem, but padding can be added (self adhesive round furniture legs pads etc), use your imagination.

Leggere, morbide, piacevoli da indossare, e perfettamente funzionantiConsigliatissime
