TELECOILS

Home / Products / Acoustic Components / Accessories / Telecoils

The telecoil is the small coil inside your hearing aids that converts electromagnetic field to electrical energy. Create your hearing loop systems thanks to Knowles’ telecoils. They can be designed as passive, surface mount, active gain, and radio frequency solutions — including improved EMI performance on active units.
