A:Answer Yes, depending on the type of audio output your TV has, you can still hear sound through your TV's speakers while this device is connected via Bluetooth. Namely, if your TV has a digital optical audio output (also known as a TOSLINK or Optical S/PDIF connection), then you will be able to use this device with Bluetooth headphones AND hear the TV's built-in speakers simultaneously, so others can still listen to the TV without headphones. If your TV does not have an optical audio output but has red/white RCA "audio out" connectors, then it varies depending on TV make/model. Some TVs will have a setting in the audio menu that will allow you to enable the TV speakers while also using the RCA audio output. If your TV only has a headphone jack, then your TV will likely mute the built-in speakers when you plug this device in, which means others won't be able to listen.
Regarding hearing aids, please make sure 1) they support the A2DP Bluetooth profile and 2) they can be put into Bluetooth pairing mode manually, without the use of an app. You will need both of these to be true in order to use your hearing aids with a Bluetooth transmitter/streamer. The manufacturer of your hearing aids will be able to provide the answers to these questions if you no longer have the user manual for them.
