## Description

PingaOculto Spy Earpiece Exams Invisible Hidden Ear Piece (Nano Pro) | Micro earpiece capsule and mini hidden spy earphones. Covert exam cheating devices to copy in exams and public tests: desertcart.co.uk: Toys & Games

Review: Need some more things - Horrible I can’t hear anything Rubbish
Review: Ugly device, complicated to operate - The earbud is nice but the rest of the equipment is so awfully ancient, looks like devices created for KGB spies from the 50's. Is not cheap

## Features

- 🕵【 Three millimetres of earpiece inside the ear 】 The Nano earpiece measures 3 mm and disappears into the ear canal, undetectable from outside. A removal bar and a removal magnet come in the kit for taking these invisible earphones back out.
- ⭐【 An exam earpiece for silent rooms 】 The earpiece works as an exam aid, and equally for presentations and discreet communication, in quiet settings such as an exam hall or a library. Some uses may breach local regulations or the rules of the centre.
- 📱【 A 3.5 mm jack for iPhone and Android 】 The induction collar connects to a mobile phone or an MP3 player through a 3.5 mm jack plug, for phone calls or for recordings, and works with all mobile phones including iPhone and Android.
- 🎙️【 A whisper microphone built into the collar 】 The induction collar carries a small concealed microphone that allows communication in whispers, so answers never have to be spoken at normal volume. Its multifunction button covers Play, Pause, Next, Previous, Answer and End Call.
- 🔋【 Around 4 hours from a single 9V battery 】 The induction collar runs on one 9V battery, which is not supplied and sits in a protective case with an ON/OFF switch, and it gives roughly 4 hours depending on the volume. The magnet earpiece carries no battery and needs no charging.
