Hearing aids that sit behind-the-ear are the most common and simplest style to fit. The device has enough physical size to house advanced microchips, Bluetooth antennas and a sizable battery. These hearing aids will have the most options available and the widest range of prices.
Typically the microphone and all the electronic “guts” are in the behind-the-ear part, but a translucent thin wire transmits sound to the transceiver that sits in a discreet black rubber dome in the ear canal. These devices are pretty simple to place and remove and have 1-2 buttons that allow for direct adjustments.
The unit itself comes in a variety of colors to match hair/skin coloring in a discreet natural manner.
RIC hearing aids are the most popular option and are made by all major manufacturers.
