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

❮ An invisible earpiece of 1.2 x 0.68 cm ❯ The Vip Pro UltraMini measures 1.2 x 0.68 cm and lodges inside the ear canal. Its conical shape follows the rising line of the canal, so these invisible earbuds are not seen from outside, not even at close range. ❮ A hidden ear piece spy for the exam room ❯ The earpiece works as a discreet cheat sheet in written and oral exams, in presentations and in interviews. In a silent hall these cheating earphones let a second person read the answer over the phone while nothing shows on the outside. ❮ Bluetooth pairing with any phone or MP3 player ❯ The induction collar pairs over Bluetooth with any Bluetooth device, mobile phone or MP3 player, for listening to recordings or taking calls in quiet and in noisy surroundings alike. The audio crosses to the earpiece by induction, with no cable reaching the ear. ❮ A wired microphone for close-range whispers ❯ The induction collar carries a wired microphone on its own lead. It is built for whispered replies at close range, so the other side hears the answer without a raised voice. ❮ About 4 hours of collar and 4 of earpiece ❯ The induction collar is recharged with the USB cable supplied and gives roughly 4 hours. The Vip Pro UltraMini earpiece runs on a 337 SR416SW button cell and gives about 4 hours, in both cases depending on the volume used. Two button cells travel in the kit.
