CooMax Spy Earpiece Hidden Wireless Earphones Invisible Headset Phone Microphone for Exam Mini Secret Headphone Listening Device Hearing in Ear Cheating Earbuds (Spy Vip Pro SuperMini)

❮ Invisible earpiece of 1.10 x 0.64 cm ❯ The Vip Pro SuperMini measures 1.10 x 0.64 cm and sits inside the ear canal, where it is hidden from view. Its conical shape follows the rising line of the canal and the dark colour of its cover resembles the bottom of the ear, so it stays undetectable. ❮ High volume in quiet and in noisy rooms ❯ This earpiece stands out for its volume and sound quality, which makes it suitable for listening to a recording or handling a phone call in a silent exam hall as well as in a noisy environment. The sound travels from the neckloop by induction, clearly and without a cable to the ear. ❮ A 3.5 mm jack for any phone or MP3 player ❯ The induction neckloop carries a 3.5 mm jack plug, so it connects to any device with that socket, a mobile phone or an MP3 player. It serves both for a live call and for a recording prepared in advance. Phones with no headphone socket need an original jack adapter, sold separately. ❮ Integrated microphone in the neckloop ❯ The induction neckloop has a built-in microphone, enough for answering through signals agreed in advance, such as a knock, and it leaves both hands free during the whole communication. A multifunction button on the cable makes the kit simple to operate. ❮ Around 4 hours per 337 SR416SW cell ❯ The earpiece runs on a 337 SR416SW button cell and gives approximately 4 hours, depending on the volume it is used at. The neckloop takes its power directly from the headphone plug, so it never has to be charged.
