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

❮ An invisible earpiece of 1.2 x 0.68 cm ❯ The Vip Pro UltraMini measures 1.2 x 0.68 cm and sits inside the ear canal, where it is not visible from outside. Its dark tone follows the shade of the ear, so nothing shows during an exam, an interview or a presentation. ❮ Sound that arrives by induction, with no cable to the ear ❯ The induction neckloop is worn around the neck, under clothing, and sends the audio to the earpiece by induction. Nothing runs between the collar and the ear, so no cable is visible at any moment. ❮ Jack connection to any phone or MP3 player ❯ The neckloop ends in a jack plug and works with any device that has a headphone socket. It serves both for phone calls and for listening to recordings, and the volume holds up in quiet rooms and in noisy ones. ❮ Integrated microphone for short signals ❯ The induction neckloop carries a built-in microphone. It is enough to answer with signals during a call, such as a knock or a cough, and it keeps both sides of the conversation on the same line. ❮ Around 4 hours from one 337 SR416SW button cell ❯ The Vip Pro UltraMini runs on a 337 SR416SW button cell and gives approximately 4 hours, depending on the volume it is used at. The neckloop takes its power from the jack plug and is never charged.
