CooMax Spy Earpiece Bluetooth Hidden Wireless Earphones Invisible Headset Phone Microphone Exam - Mini Secret Headphone Listening Device Hearing Cheating Earbuds (Spy Vip Pro UltraMini BT IM)

❮ An earpiece of 1.2 x 0.68 cm in the ear canal ❯ The Vip Pro UltraMini measures 1.2 x 0.68 cm and its dark colour follows the tone of the ear, so it blends in and stays out of sight while it is worn inside the ear canal. ❮ Induction sound, with no cable to the ear ❯ The induction collar passes the sound straight to the earpiece, clear and crisp, which is what makes the volume enough for a recording or a call in a quiet room as well as in a noisy one. ❮ Bluetooth 4.0 with any mobile or MP3 player ❯ The induction collar carries universal Bluetooth 4.0 connectivity and pairs with any Bluetooth device, a mobile phone or an MP3 player, so it serves for calls and for a recording prepared in advance. ❮ A microphone built into the induction collar ❯ The collar holds its own microphone, which allows two-way communication and is enough to reply with agreed signals such as a knock. Its multifunction button keeps the phone out of the way. ❮ 4 hours of collar and 4 of earpiece ❯ The collar charges with the USB cable supplied and gives approximately 4 hours depending on the volume. The earpiece runs on a 337 SR416SW button cell and gives about 4 hours as well, and 2 cells travel in the kit.
