Bluetooth streaming directly into hearing aids. On the phone particularly, bluetooth streaming allows me to hear the speaker with both ears instead of one, greatly aiding my comprehension. A bluetooth streaming device connected to the computer allows me to participate in Zoom exercise classes without having to watch the screen at all times. Bluetooth streaming of movies and TV into hearing aids hugely enhances my understanding and experience, as I'm less dependent on captions. It's a quality-of-life game changer.
