Which headphones for training?

[otomops]

I would like to watch TV while training on my Concept2 so am looking for advice on which cordless headphones to use and how they can link with a TV or DVD player. Any advice?

I just use a 6' extension cord for my headphones. I have to clip it in a couple places, on my shirt and on my hip, so it doesn't get in the way.
