A:AnswerWe have had success pairing to some hearing aids. Unfortunately, due to the vast number of hearing aids I cannot guarantee that this will work with your particular model.
A:AnswerIt depends on your TV and how it handles audio output. One way around this is to connect the transmitter directly to your cable box instead of the TV...then you get audio from both. However, this will only transmit audio from your cable box and not any other connected devices ie DVD player etc.
A:AnswerYes, if you have a 3.5 mm or SPDIF audio output on your projector and a 3.5 mm or SPDIF audio input on your soundbar, you could use this device.
