I read the earlier comment regarding the 850s as well...I used them for two years and they were just fine. Just to be part of in crowd, I purchased the Bose A20s. They are nice but bulky and cumbersome...and somewhat uncomfortable when you wear them for a while. Uflymike has some issues too...unlike the A20s, once the batteries go you must change them or revert to the company headset. Now that is a POS. Check out the Clarity Aloft.
