A new bluetooth Earphone

I found a new bluetooth earphone, from the company Bellboy.
I’m contacting it to try this product.
It’s a new revolution :

The earphone is very comfortably placed in the ear.

The structure of the speaker is perfectly anatomically suited to the ear and provides a clear, sharp sound that is devoid of background noise.
The earphone battery is charged through the computer or directly plugged into an electric socket.
The earphone cable is flat and doesn’t get jumbled even if you stuff it deep into a pants pocket.

The cellular phone function will express the state of charging battery.
