Sure. There are a few

Just look for models that include 'digital optical audio' outputs in the model specifications listed on Best Buy's web site. Two Examples:

Limit the size to 40-59", then look through the model specifications. It might be tricky to get a wifi enabled one though at that size. The above models may accommodate wifi via a dongle though. Look in the online user manual on the manufacturer's web sites using the above models.

The wireless headphones would have to have a transmitter that can connect via the digital optical output of the HDTV. If you ended up with a wireless headphone model which does not accommodate digital optical, you would need some sort of converter (digital optical--> RCA).

Bad news is, such headphones are generally harder to find and pricey. One example is the Sony MDR-DS6500 ($200).
