PingaOculto Spy Earpiece Bluetooth Wireless Earphones Invisible Hidden Mini Headset Exam Phone Microphone - Secret Earphone Micro Listening Device Ear (Spy Vip Pro SuperMini Pen)

🕵【 Invisible earpiece of 1.10 x 0.64 cm 】 The Vip Pro SuperMini earpiece measures 1.10 x 0.64 cm. Its conical shape follows the rising curve of the ear canal, so it stays completely hidden once in place, and it still gives volume and sound quality enough to be used in a noisy room. ⭐【 A pen that writes, with black ink included 】 The body is a working pen and a black ink refill cartridge comes with it. There are no visible buttons and the body does not come apart, so on an exam desk it reads as ordinary stationery rather than as a device. 📱【 Bluetooth 4.0 to iPhone and Android 】 The pen connects to a mobile phone over Bluetooth 4.0 and passes the sound through to the earpiece. Phone calls and recordings are both covered, and it is compatible with all mobile phones, iPhone and Android included. 🎙️【 A microphone inside the pen for whispering 】 A small microphone is built into the side of the pen. It picks up whispered speech at close range, which allows a two-way exchange without the voice being raised. 🔋【 3 hours of pen and 4 hours of earpiece 】 The pen carries a built-in rechargeable battery and a USB charging cable comes with it; it gives about 3 hours, depending on the volume of the call or the recording. The earpiece runs on a 337 SR416SW button cell for roughly 4 hours.
