Wireless Headphones for TV

To minimize possible interference from other household devices, headphones using the 5.8Ghz frequency band would usually be preferred over 2.4. That said, 2.4 can work fine depending on the infrastructure/interference at any given location. UHF is definitely better than IR (or 900MHz, for that matter).

If so, I would go for IR. IR need line of sight to work so that you don't have interference between the two tv. The draw back is that you can roam around the house with it.

Living in an apartment and not wanting to disturb my neighbors, I did quite a bit of reading on wireless headphones -- initially for use with my TV. So that I didn't limit my usage of the wireless headphones, I settled on a pair of Bluetooth 'phones from Best Buy (price range: $40 - ~$120+). The ones I chose were RocketFish @ about $60. Logitech makes a Bluetooth dongle ($40 from Amazon) with RCA audio input from your TV. Bottom line -- you have your wireless headphones for TV, plus you throw them in your shoulder bag and use them with your laptop also when you hit the coffee shop or other public WIFI spot. The real audiophile would probably not look twice at them, but they're fine for me, and I get double duty.

which is better depends on each TV, you should tell detail which TV you use
