Press Release:Wireless headset TopPro BT-3 consists of a micro-handset, which captures the transmitted call thanks to the induction loop, and a wireless Bluetooth module. The design and shape of the earpiece ensure a firm yet hidden fit in the ear canal, while the induction loop module can be hidden under clothing. Thanks to this, you can easily make phone calls completely hidden and unobtrusive. A connected smartphone can be stored anywhere within ten meters.
The TopPro BT-3 headset easily connects to a mobile phone via Bluetooth. The induction loop together with the communication module is hidden under the clothing and thanks to electromagnetic induction transmits the sound to a miniature earpiece that serves as a receiver. The earpiece is placed in the ear canal and is almost invisible to the surroundings. Thanks to its high sensitivity, the built-in microphone picks up even quiet sounds, so the call can be conducted in a whisper, secretly and very discreetly. The handset is powered by a miniature battery and lasts for up to five hours. The module with a Bluetooth connection and an induction loop is charged via a USB port and allows you to talk for twelve hours. In standby mode, the module can last up to one hundred hours. The module has a button not only for volume control, but also for receiving and ending a phone call.
“The TopPro Inductive Loop Spy Invisibility Earpiece BT-3 is one of our best-selling covert communication devices. It's easy to use,” explains Damian Teichert, SpyShop24.cz marketing manager for the Czech Republic, adding: "The handset uses electromagnetic induction technology, and its size can therefore be as miniaturized as possible. The module with the induction loop, Bluetooth connection and battery is located separately, under the clothing.
