The principle of operation is very simple – sounds are directed to the user via a very sensitive micro earpiece while the induction loop with a microphone enables establishing a connection with a phone using Bluetooth technology and thus to communicate with the other participant of the conversation. It is very easy to camouflage and operate – these features makes the device a perfect tool for business meetings and negotiations. Additionally, it may be used as a help during exams or tests.
The earpiece was designed to ensure maximum comfort of use while retaining the smallest possible size. The earpiece adjusts itself to the ear canal, and allows additional regulation, which makes it comfortable and provides good reception of sounds. One battery lasts for 5 hours of continuous use.
To establish a communication between the inductive loop and the mobile phone, the latter must feature Bluetooth® function (the distance between the phone and the loop cannot be more than 10 meters). Bluetooth® loop can be charged via a USB cable. The loop enables communication by establishing a connection with the micro earpiece, using a sensitive microphone capable of capturing even very quiet sounds. Convenient buttons ensure comfortable operation and allow to listen to the recordings, switch between them, and pick up or end phone calls.
The communication between the participants of conversation is done by establishing a normal connection with the user's mobile phone. You can make a call with either a mobile phone, a landline phone, or VoIP.
The mobile phone of the user should be connected with the induction loop placed on the neck. The loop, using electromagnetic induction, transfers the sound from the phone to the micro earpiece. Sensitive microphone placed on the loop allows to conduct a discreet conversation.
