I dd bump my other thread but it went unnoticed so I'm making a new one, hope you don't mind too much! 
Further to my quest for wireless headphones for my mum, I'm now wondering about bluetooth for TV instead of just regular wireless. As far as I've discovered, I can plug a bluetooth device into the optical out of the TV and control the volume on the bluetooth headphones (if they have a volume control), and it also means nothing has to be unplugged to switch to TV speakers as it works independent. The TV speakers can be just be muted with the mute button I think. If this is the case, I wonder if this device would be correct?

Or anything similar and cheaper like that which uses optical out? And bluetooth headphone with volume control?
