Question

Hooking wireless Headphone to LG's 47LA6250 Smart TV

Oct 7, 2013 10:48PM PDT

I have used the 1) Sennheiser and 2) Sony wireless headphones on my LG 47LA6250 TV by connecting them through the 3.5mm 'HP Out' on the back of the TV. The connection works for up to 5 minutes and dies. To re-establish connection, I have to unplug and plug back. Again, the headphone reception dies after a few minutes. Is there a fix for this?

R. Proffitt, yes, it works wired. Do you suspect it is the weak wireless signal?

(In my set up, the wireless transmitter is connected to the TV by a 3-meter wire and the receiving wireless headphone is about 4 meters away. Everything is in the bedroom and there is no wall or any obstruction.)

Best regards,
Basil

Thanks R. Proffitt & Bob.
R.P, if I read you correctly, do you mean that all 3 wireless items that I bought were defective?
Bob, will do.

Sorry but without testing I could not determine this.

But if the headphone works directly and does not when we add a new part then it's the new part that's the problem.

I did take the extra step to check distance and what RF frequency (900MHz) that product used and maybe there is other gear in the home that uses that but I would not have that detail.

-> Another test would be to use the headphones on a PC and if that's fine, add the wireless link. But given there can be interference that test isn't as conclusive but I would do it.
