Inductive Bluetooth Necklace Loop Black with Mic

How the system works:
The first step is to connect the collar to your mobile phone via Bluetooth. The mobile phone can then be hidden and no longer used to manage the device.
Next, the battery is inserted into the earpiece.
Everything is ready!
From this moment on, anyone, from an UNLIMITED distance, can call the mobile number or make a call (even directly from the collar).
They will hear your voice from the earpiece placed in their ear and will hear your voice (even if you whisper) thanks to the microphone placed inside the Bluetooth collar.
