I have discovered that there are two options, which are bluetooth and kleer audio.
Bluetooth is lossy much like JPEGS and MP3, and unless your kit has the latest codec, which is usually pre-plumbed into your kit then you can not update to the latest codec's for the best sounding bluetooth.
Kleer is like bluetooth however it is lossless and uses less battery power to run it, or so the blurb says.
I was going to go down the road of bluetooth until I discovered that my phone does not have the latest codec's to get the full benefit so I go a wired pair of headphones..
A month ago I was round my parent's house and noticed that my dad was using a pair of wireless headphones to listen to the TV. Something to do with being deaf as a post and not wanting to blast my mom's ears while they watched telly. These headphones were awful with hissing and interference all over the place.
I did a bit of research for some wireless headphones and stumbled onto Kleer as an alternative to bluetooth. I took a punt and bought my dad some Sennheiser RS headphones. I have to say that the sound quality is exceptional with this setup. Crystal clear with no interference or hissing anywhere. The headphones were as good as my wired headphones.
I'd recommend a company that uses Kleer technology if you don't want to go down the bluetooth route.
