We are looking at headsets that would be connecting directly via the 2.5" jack. A quick Disconnect would be nice, but ulitmately, we qould be looking at a mono headset that can be worn over the ear or in the ear, while still being a wired connection. Voice tube is a good choice but we are all leaning towards noise canceling I believe. Any specific make/model suggestions? I'd really appreciate a ballpark price for the individual unit(s) if possible as well.
