I have Sentry H1000 wireless headphones. There's a transmitter that you hook up to the tv or whatever and you turn the headphones on and you can hear whatever you are transmitting through the transmitter. It operates at 49.85 MHz. Is there any way I can somehow get a speaker or something that has a speaker to receive at that same frequency and so I can be able to hear it through that speaker? If so, what and how would I go about doing that? Thank you so much!
