🕵【 Two earpieces, 3 mm and 1.10 x 0.64 cm 】 The kit holds two different earpieces. The Nano magnet measures 3 mm, carries no battery and is the more discreet of the pair. The Vip Pro SuperMini measures 1.10 x 0.64 cm and gives more volume. Both sit inside the ear canal, where they are not visible from outside. ⭐【 A cheat sheet for exams and oral tests 】 The exam earpiece stands in for a written cheat sheet in tests and public examinations, and it also serves for presentations or discreet communication. The magnet earpiece is the quieter of the two and suits silent places such as an exam hall or a library. Some uses may fall outside local rules. 📱【 A 3.5 mm jack plug into any mobile phone 】 The induction neckloop connects to a mobile phone or an audio player through a 3.5 mm jack plug, which covers both phone calls and recordings. It is compatible with all mobile phones, iPhone and Android included. 🎙️【 A microphone built into the neckloop cable 】 A small microphone sits in the cable of the hidden neckloop. It carries short signals, such as a cough or a knock, and whispered speech at close range. 🔋【 3 hours of neckloop and 4 of earpiece 】 The V3 induction neckloop has a rechargeable battery and gives roughly 3 hours depending on the volume. The Vip Pro SuperMini runs on a 337 SR416SW button cell for about 4 hours. The magnet earpiece needs no charging and carries no battery at all.
