Discovery 975 Replacement Head

Pros: great voice quality BOTH from mic and speaker

Cons: seriously nothing

Summary: I have had many headsets. The Plantronics 520 although not stylish was the best until this one. quality is excellent. I thought the little charge box was stupid at first until i used it. You can get 2 to 3 charges out of it. So that means if you charge everything up, use the headset, you can charge it from the box at lease 2 more times before having to plug in. pretty cool. People dont know im using a cell phone. Noise canceling is very good. Speaker quality on receiving end is great. I can not stand headsets that makes people sound like they are talking into tin cans.
