Overview

The Williams Sound NKL 001 Neckloop is an assistive listening accessory designed for individuals with moderate to severe hearing loss who wear hearing aids equipped with a telecoil (T-coil) switch. When worn around the neck and connected to a compatible FM or IR receiver via its 3.5mm monoaural plug, the neckloop generates an electromagnetic field that the hearing aid's T-coil picks up directly. This bypasses background noise and delivers the audio signal straight to the listener's hearing aid, making it particularly useful in environments like houses of worship, lecture halls, theaters, and conference rooms where assistive listening systems are installed.

The adult-sized loop features an integrated safety breakaway device — a deliberate weak point in the cord that separates cleanly if the neckloop catches on a chair, door handle, or other object, preventing injury. It reconnects just as easily. With an impedance range of 8 to 16 ohms and a straightforward plug-and-wear design, the NKL 001 requires no setup beyond switching the hearing aid to T-coil mode and connecting to a receiver. It is a focused, single-purpose accessory that does one job — delivering clear audio to T-coil hearing aids — reliably and safely.

Frequently Asked Questions

It works with hearing aids that have a T-coil (telecoil) switch. When the hearing aid is set to the T-coil position, it picks up the electromagnetic signal from the neckloop and converts it to sound.
