We like this product from headsets.com
I am trying the headset and amp out.
It works pretty well and is comfortable.
I am wondering about noise cancelling features next.

very satisfied
I recieved my headset in a very quick timely manner. Everything was packaged great. They even included a couple of tootsie rolls!! What a nice treat. I had to call customer service for a little help and they were awsome, friendly and very accurate.
