Many modern hearing aids are Bluetooth®-enabled, allowing you to connect them to your TV, tablet, smartphone or any other device, essentially making your hearing aids headphones. While the history of hearing aids precedes headphones by many centuries, their history became closely intertwined during the 20th century.

Now, with wireless technology and Bluetooth®, the lines between hearing aids and headphones aren’t as clear cut. Because when you look at the major developments in hearing aid and headphone technology, it’s clear to see how closely linked hearing aids and headphones really are.
