PingaOculto Spy Earpiece Bluetooth Wireless Earphones Invisible Hidden Mini Headset Exam Phone Microphone - Secret Earphone Micro Listening Device Cheating (Spy Nano V4 + Vip Pro UltraMini)

🕵【 Two mini earbuds, hidden inside the ear canal 】 The kit carries two earpieces for the same neckloop: the Nano V4 magnet capsule and the Vip Pro UltraMini of 1.2 x 0.68 cm. Either one lodges inside the ear canal and stays out of sight; the magnet earpiece announces incoming audio by vibration. ⭐【 A cheat sheet for exams and presentations 】 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 these cheating earphones go unnoticed. 📱【 Bluetooth 4.0 with iPhone and Android alike 】 The induction neckloop pairs over Bluetooth 4.0 with all mobile phones, iPhone and Android included, for phone calls and for recordings. The audio travels from the neckloop to the earpiece by induction, with no cable reaching the ear. 🎙️【 A microphone integrated in the neckloop 】 A small microphone is built into the induction neckloop, which is worn under clothing. It carries short replies whispered at close range, or a cough or a tap when speaking is not an option. 🔋【 About 4 hours of neckloop and 4 of earpiece 】 The V4 neckloop is rechargeable and gives roughly 4 hours depending on the volume; the charging cable and the charger travel in the kit. The Vip Pro UltraMini runs on a 337 SR416SW button cell for about 4 hours and two cells are supplied. The Nano magnet earpiece needs no charging and carries no battery.
