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

❮ 1.2 x 0.68 cm of earpiece, dark and conical ❯ The Vip Pro UltraMini measures 1.2 x 0.68 cm and its dark colour follows the tone of the ear, so it disappears inside the ear canal and is not noticed from outside. ❮ A pen that passes the sound by induction ❯ The pen holds the induction transmitter, so nothing has to be worn around the neck and nothing reaches the ear by cable. The sound arrives clear and crisp, with volume to spare. ❮ Bluetooth 4.0 with any mobile or MP3 player ❯ The pen 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 integrated in the pen ❯ The pen holds its own microphone, meant for secret communication in a whisper, and its multifunction button keeps the handling simple while the phone stays out of the way. ❮ 3 hours of pen and 4 of earpiece ❯ The pen charges with the USB cable supplied and gives approximately 3 hours depending on the volume. The earpiece runs on a 337 SR416SW button cell and gives about 4 hours, and 2 cells travel in the kit.
