PingaOculto Spy Earpiece Wireless Earphones Invisible Hidden Mini Headset Exam for Phone with Microphone Secret Earphone Micro Listening Device Hearing in Ear Cheating Earbuds (Spy Nano)

🕵【 A 3 mm earpiece inside the ear canal 】 The Nano earpiece measures 3 mm and sits inside the ear canal, where it is hidden from view. It carries no battery and is never charged: the induction collar generates the vibration that produces the sound. Two of these earpieces come in the kit. ⭐【 For exams, oral tests and public competitions 】 The exam earpiece works as a cheat sheet for exams, and the same earphones are used in presentations and in discreet communication. ⚠️ Some uses may breach the rules of the exam centre or local law. 📱【 Jack connection to the phone, with no cable to the ear 】 The induction collar plugs into a phone or an MP3 player by jack and serves both a live call and a recording prepared in advance. Between the collar and the ear nothing runs. ⚠️ Phones without a headphone socket need a separate original jack adapter. 🎙️【 Microphone built into the induction collar 】 The induction collar carries a built-in microphone, enough to answer with agreed signals such as a tap or a cough. Its multifunction button covers play, pause, next, previous and answering or ending a call, so both hands stay free. 🔋【 Between 7 and 8 hours of induction collar 】 The collar gives between 7 and 8 hours depending on volume. ⚠️ It runs on 2 x 9 V batteries that are not included in the kit and are bought separately. The earpiece needs no charging at all, because it holds no cell.
