Finally, for those who like to chat on the phone at a disco, or in any other noisy place, they invented a device that allows you to convey to the interlocutor the necessary information, and at the same time he will not hear any extraneous noise. The device, developed by the Japanese company NS-ELEX with Sanyo, consists of an earpiece and an amplifier unit. A headset inserted into the ear picks up the vibrations of the air in the ear canal when you are talking and transmits a signal to an external amplifier device that amplifies the signal and removes the noise. Then the processed signal is transmitted to the phone via wire or via Bluetooth. Sales of the device will begin in April of the following year and the expected price of 40,000 ¥ ($ 353) for the wired version or 60,000 ¥ ($ 530) for the gadget with Bluetooth.
By the way, according to the manufacturer, e-Mimi-kun (the so-called device) suppresses external noise ten times, which allows you to tell your parents that you stayed in the library while being in a more fun institution.
