I'll second the Sennheiser RS 140. I actually own a set of the RS 110 (non-rechargeable and similar). I only opted to get those due to price ($40 shipped from Dell) about 4 months ago.
The RS110's sound good for TV and non-critical listening. However if the price difference was only $20 to the rechargeable unit I would have opted for that, though I have yet to replace the battery. And I am using 2xAA NiMh's.
Good luck
