How does Bluetooth work?
The technology utilizes radio waves to send signals between devices through a process known as streaming. Radio waves from two or more devices can “talk” invisibly over a range up to 30 feet. This means you can be standing far away from your television or music player and still stream sound directly into your hearing aids. Streaming is bi-directional, which means you can not only hear sound from other devices, you can feed sound back. So, if you’re taking a hands-free phone call in the car, not only can your hearing aids stream the sound from your phone directly into your ears, when you speak, your voice will be streamed seamlessly back to the phone.
