Discreet communication in a self-contained kit
Your SIM handles the call
The neckloop contains its own GSM module. Insert a compatible SIM to communicate without pairing a separate phone.
Incoming calls answered automatically
Your contact calls the SIM number. SilentWave answers automatically and sends their voice to the concealed earpiece.
Listen and respond
Receive information through the inductive receiver and reply through the preamplified microphone. The connection supports a two-way conversation.
Full description
A direct line to your contact, without a phone
SilentWave combines an invisible earpiece with a GSM neckloop for situations where communication needs to stay discreet. The neckloop holds the SIM and handles incoming calls itself. Automatic answering lets you receive information without reaching for a handset.
Audio travels from the neckloop to the earpiece through induction, with no external wire running to your ear. A preamplified microphone picks up your voice, including quiet speech with the neckloop worn under clothing. Keep the receiver within 25–30 cm of the loop. A compatible GSM network and SIM are required.
Separate batteries for the neckloop and earpiece
The neckloop has a built-in rechargeable 3.7 V lithium battery and provides up to 5 hours of talk time under ideal conditions. The earpiece uses a replaceable SW 337 battery, with up to 10 hours of runtime under ideal conditions. Actual runtime varies with use.
The kit includes the inductive earpiece, GSM neckloop, and high-sensitivity microphone. The in-ear receiver is intended for individual personal use. Send us your country and carrier before ordering so we can verify compatibility with the supplied GSM configuration.
