I expected it to be at least better than Plantronics black wire c310 due to its price but when I first tried it for work, it's obviously the lesser headset. I believe it has to do with the manufacturer. My Blackwire was made in Mexico whereas Evolve was manufactured in China.
I like the cushion ear phones adds to focus; Mic quality is clean though volume is still low even when sensitivity set to highest
noise cancelling is second rate compared to plantronics blackwire c310; Also, microphone is low even when set to highest; Playback also second rate
