charging tv bluetooth transmitter

[movingtables]

a question before i buy a bluetooth transmitter for my television.

So the idea is: to use bluetooth wireless headphones on my tv.

the transmitter plugs into my phono port but i noticed these transmitters can be charged
via usb cable (micro to full size) so i was wondering could i have the usb charge cable connected
to the tv's usb port at the same time to keep it charged?

cheers.

Surely it's the headphones, not the transmitter, that need to be charged up?

the headphone charging isnt an issue.
and yes the transmitter requires charging also.

Yes. Leave the BT transmitter permanently connected to one of the tv's usb to keep it charged.

is that a guess or a fact?
just checking
