"Bluetooth enabled hearing aids use this wireless technology twofold. Bluetooth wireless technology allows for communication between two hearing aids. This helps to get the most natural hearing enhancement possible. The two hearing aids "talk" to each other to make instantaneous enhancements to improve hearing. Another exciting function of Bluetooth enabled hearing aids is wireless connectivity with other Bluetooth enabled devices such as cell phones and music players. This technology is a vast improvement over hearing aids in the past which were often incompatible with other devices."
The Ear Level Instrument (ELI), is a Bluetooth-enabling device for hearing aid wearers. Those who wear hearing aids can identify with the inconvenience of using communication devices – but not anymore! With Bluetooth connectivity, you can now listen to music and talk on your phone while having your hearing aid in place. The external microphone is overridden by ELI when using a Bluetooth device so that the user gets uninterrupted, clear access to the sound minus static and feedback.
