PingaOculto Spy Earpiece Bluetooth GSM Exams Invisible Hidden Mini Wireless Earphones in-Ear Microphone - Micro Discreet Copy on Phone Call (Spy Nano Piece + Vip Pro SuperMini)

🕵【 Two earpieces hidden inside the ear canal 】 The kit carries the Nano magnet earpiece, 3 mm across, and the Vip Pro SuperMini, 1.10 x 0.64 cm. Either one works with the same inductor piece: the magnet one is the more discreet, the Vip Pro gives more volume. ⭐【 A cheat sheet for exams and oral tests 】 The earpiece serves as an exam cheat sheet, and also for presentations and discreet communications. The magnet earpieces suit silent rooms such as an exam hall or a library, where nothing may be held in the hand. 📱【 A hidden phone with a Nano SIM card inserted 】 The inductor piece runs two ways: paired with a mobile over Bluetooth 4.0, for calls and for recordings, or on its own with a Nano SIM card inserted, which turns it into a hidden phone that can be rung for voice calls on the 850, 900, 1800 and 1900 bands. 🎙️【 A microphone built into the inductor piece 】 The inductor piece is worn between the neck and the chest, under clothing, and carries a microphone inside it, so replies can be whispered at close range without a raised voice. 🔋【 About 3 hours of piece and 4 of earpiece 】 The GSM BT piece has a built-in rechargeable battery and gives roughly 3 hours depending on the volume, recharged over a USB-C cable. The Vip Pro SuperMini runs on a 337 SR416SW button cell for about 4 hours and the kit carries two. The magnet earpiece needs no charging.
