A:Answer It's wired only.
If you mean an older television as in something without a USB port, the answer is no. I tried plugging in the headphone lead and plugging the USB lead into a 2.1 amp charger, but there was no sound.
I don't have a newer TV (headphone jacks plus USB ports) to test this on, but I think the answer would be no there too since this would be similar to the headphone+USB charger method I tried.
