Bluetooth Hearing Aids
Bluetooth-enabled hearing aids allow the wearer to connect devices to them.
One type of Bluetooth device is a streamer (like a TV adapter that sends the signal straight from the source to your hearing aids).
Another Bluetooth device could be your phone. Compatible phones have apps that you can download giving you access and control over your hearing aids. They allow for a most customized hearing experience as you are able to change the overall volume or lower/heighten specific frequencies for the task at hand.
