What kind of headphones do you use, and/or what codecs do they support?

I have Aptx low latency headphones I use primarily for TV, and use this monoprice and an old MPOW with AptX low latency (this one I think) and find they both work well. I found the low latency support was important for me on headphones and transmitter at the time, otherwise audio sync was too far off. Also supports AptX HD and AAC for higher quality when primarily listening, and ability to use optical in and bypass my TVs headphone jack was a nice feature on the Monoprice.

Avantree is another good brand I’ve used in the past. Mostly would recommend you find something with the codecs and inputs that are important to you.
