Using a WEP 200 on a 650. When I started using it (about 2 months ago), the performance was great. Call quality was great -- inbound and outbound. No problems with any functionality.

Now, I am hearing static (that was never present) and people are complaining re: the sound of my voice.

(Bought the unit through TreoCentral, so am not too concerned about a fake product).

Any thoughts on whether this is the headset or a 650 (which I have had for a while) that is causing the problem.
