Review on Sennheiser Wireless Telephone Certified Refurbished by Michael Vargas

Incredibly light/comfortable. I wish the boom arm was a bit more adjustable in terms of right to left placement, but the 360 degree rotation is cool. The battery lasted all day (8+ hours) before needing a charge. The sound is way better than headsets I've used in the past, including another Sennheiser, but it's almost too good. I've been able to fix this in some settings that I haven't found yet, but the noise-cancellation sometimes causes gaps in the audio for my listeners as it tries to adjust to sudden noises like my heater turning on. Also, the audio doesn't always pick up right away, and I have to rewind the clip to hear the first few seconds.
