A HANDS FREE, WIRELESS NECK LOOP The T-DEX is a hands-free, wireless neck loop for use with all hearing aids with a telecoil. It lets you easily connect with Bluetooth mobile phones. The T-DEX comes with a built-in rechargeable battery, as well as a charging cord.
Because it amplifies the sound from the mobile phone, the T-DEX is perfect in situations where there is a lot of background noise. And its hands-free operation means that it is easy to talk on the phone while driving for example.
Simply place the T-DEX around the neck and activate it when the phone rings. The sound is transmitted wirelessly to the hearing aids so you can hear and converse directly. Calls can be easily answered and ended by means of a single push button.
