Product Overview

This deceptively simple looking loop acts as a wireless connection to hearing aids equipped with a "T" coil.

What is a Telecoil?


ListenTALK Jack Sense Overview


Listeners hook the loop into their wireless receiver, slip the loop around their neck, and the "T" coil picks up the sound and amplifies the transmitted sound into the ear.



  • Use with any hearing aid equipped with a “T” coil
  • Use with any Listen’s receivers
  • The receiver’s antenna is built into the headphone cord
