A very nice bass and takes away almost all the noise. I don't workout with them but with the right size cone I would thing ther would. A nice pair of earbuds. I got mine for around 20.00 hope you are too becuse they are well worth that price.
I do not know for sure though they might work if you could plug them directly into a TV as long as you have a 3.5mm audio port. They don't work to well if I plug them directly into my 500 Watt stereo receiver, but they work great on an mp3 player.
