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 Mini)

❮ Invisible earpiece of 1.14 x 0.7 cm ❯ The Vip Pro Mini measures 1.14 x 0.7 cm and sits inside the ear canal, where it is hidden from view. The dark colour of its cover resembles the shade of the inner ear, so the earpiece stays out of sight while it is being worn. ❮ Induction sound with high volume ❯ The neckloop is worn around the neck, under clothing, and transmits the sound to the earpiece by induction. The volume and the clarity are enough for listening to recordings or taking phone calls in a silent room and in a noisy environment alike. ❮ Jack connection to any 3.5 mm socket ❯ The induction neckloop ends in a 3.5 mm jack plug, so the source is connected through that socket. Nothing runs to the ear: only the neckloop is connected, and it stays under the clothing. ❮ Microphone integrated in the neckloop ❯ The neckloop carries a microphone built into it, placed near the collar. It is enough for communication by signals, such as a knock or a short sound, and nothing extra hangs from the neck. ❮ 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 induction neckloop does not need to be charged at any point.
