Anybody out there recommend a bluetooth transmitter for an Avtex TV? We have a bluetooth speaker, but the Avtex doesn't have bluetooth. I have 'googled' transmitters and have received many, many 'best' to buy ideas. Could really do with advice from Funsters please. I am assuming (correctly???) that the transmitter will plug into the headphone socket which is on the side of the Avtex and then chat to the the speaker when TV is on? Is this correct? Many thanks!
