Wonderful bluetooth headset.  Great sound and minimal background noise for those on the other end of the phone.  Connected easily to my Sanyo Katana II cellular phone as well as my bluetooth USB device for both use with both my Skype and Vonage talk accounts.  Only complaint, the volume control could be easier to adjust.  I end up using the the volume control on the phone which is a bit easier and I can see where the level setting is at.
