A discreet connection from your wrist to your ear

Hear your contact

The watch receives call audio from your phone over Bluetooth, then sends it to the earpiece through induction.

Speak through the watch

The built-in microphone picks up your voice and routes it back through the phone, supporting a two-way conversation.

Keep the phone nearby

Your phone can stay in a pocket or bag within Bluetooth range. The cellular call handles communication with your remote contact.

Full description

Receive instructions without an exposed headset

BT-WATCH pairs a Bluetooth watch with a miniature Secret Ear receiver for discreet communication. Spoken cues reach the concealed earpiece, while the microphone in the watch lets you answer your contact. The setup is designed to keep the audio connection unobtrusive.

Your phone handles the call and sends audio to the watch over Bluetooth. The watch then transmits it to the earpiece through electromagnetic induction. Send us your phone model before ordering so we can check Bluetooth calling compatibility.

Two local connections, one phone conversation

The phone-to-watch Bluetooth range is up to 33 ft (10 m). The specified watch-to-earpiece receiving distance is 30–50 cm, or about 12–20 inches. Communication with the other caller depends on phone service, rather than the short-range induction link.

The watch has a built-in rechargeable lithium battery. The kit includes one Secret Ear earpiece, one Bluetooth-inductive watch with microphone, one battery, and one standard connector. Watch styling may vary with stock availability. The receiver is intended for individual personal use.
