The unit was a little harder to set up than I anticipated. I had to ask a co-worker that has one to lend me hand. The instructions are OK, but the not the best I've ever seen. I heard from all my co-workers and saw online that Plantroics was better then GN Netcom, so that's why I bought this unit. I have used the corded GN units for years and found their instructions to be better. To be fair, however, this is my first cordless. The sound in the speaker in my ear is sort of like hearing in a can (I'm getting used to it), but everyone that hears me says it's really clear and much better than my previous headsets, so that's better for business. A good unit overall.
