CooMax Spy Earpiece Hidden Wireless Earphones Invisible Headset Phone Microphone Exam Mini Secret Headphone Listening Device Hearing in Ear Cheating Earbuds (Spy Vip Pro + Microphone)

❮ Invisible earpiece of 1.14 x 0.7 cm ❯ The Vip Pro Mini measures 1.14 x 0.7 cm, which is why it disappears once it is inside the ear canal. Its dark cover takes the shade of the inner ear and stays hidden. ❮ Wired microphone for whispered speech ❯ The induction neckloop comes with a microphone on a wire, which is what allows a whispered answer instead of a knock or a signal. The wire is thin enough to be hidden in a sleeve or under the collar. ❮ Jack connection to a 3.5 mm socket ❯ The neckloop ends in a 3.5 mm jack plug, which is the socket it has to be driven from. Both a live phone call and a stored recording reach the ear the same way. ❮ Induction sound with high volume ❯ The neckloop is worn under clothing and passes the sound to the earpiece by induction, with no cable reaching the ear. The volume holds in a silent room and in a noisy one alike. ❮ About 4 hours per button cell ❯ The Vip Pro Mini earpiece runs on a 337 SR416SW button cell and gives approximately 4 hours, depending on the volume at which it is used. The neckloop itself is never charged.
