Yes. Stemoscope supports Bluetooth hearing aids. Stemoscope transmits the audio signals to your phone and your phone transmits the process audio signals to your Bluetooth hearing aids, both via Bluetooth, so you can hear the sounds in real time. Your phone works as a streamer.
Here is how you can simply decide whether your Bluetooth hearing aids are supported. Do your Bluetooth hearing aids connect to your phone to listen to music or answer calls? If yes, you can hear the Stemoscope sounds in the same way because you can use your Bluetooth hearing aids to hear the sounds from the phone.
