Induction to your ear
The neckloop sends audio to the miniature receiver through electromagnetic induction. Keep the earpiece within 25–30 cm of the loop.
A conversation beyond the room
Talk with a colleague wherever cellular service supports the call. The Bluetooth range applies only to the local phone-to-neckloop connection.
How it works
Full description
Discreet communication without an exposed headset
EAR-GSM is designed for situations where you need information from a remote contact without drawing attention to the communication. Spoken cues reach a small, skin-tone receiver inside your ear, with no external earpiece wire. The microphone lets you reply, keeping the exchange two-way.
Bluetooth connects the phone to the neckloop; induction connects the neckloop to the earpiece. Your phone can be up to 33 ft (10 m) away from the loop. Despite the EAR-GSM model name, the kit uses your phone for cellular service. Send us your exact phone model to check Bluetooth calling compatibility.
Replaceable earpiece battery, rechargeable neckloop
The earpiece uses a replaceable SW 337 battery and runs for up to 10 hours under ideal conditions. Actual runtime varies with use. The neckloop has its own built-in rechargeable 3.7 V lithium battery.
For a different microphone position, request the optional extended Knowles microphone. This prefiltered digital microphone can be positioned near the wrist to pick up a quiet voice. Contact our team to discuss the configuration. The in-ear receiver is intended for individual personal use.
