The ANC we’ve been waiting for? The Sileton add-on for headphones filters the voice of callers

Are you convinced by the sense of a gadget that changes the ANC mode of any headphones so that muting the noise from the environment ignores the voices of the interlocutors? Such a gadget called Sileton was developed by Suhyun Tech from South Korea.

Sileton requires a connection with TWS headphones and a smartphone. It acts as a separate filtering device

The ANC function, present primarily in TWS headphones, is in theory simple to operate. The microphones present in them collect noise from the environment, reverse its phase and generate simultaneously the processed sound with the songs played. This makes background noise inaudible to the user, which is usually countered by the Hear-Through function (as opposed to ANC). Most headphones (see, for example, Olive Pro) do not offer something “in-between”, such as filtering voices in the ANC mode, or general noise from the environment. This changes with Sileton.

Coming down to an oblong gadget the size of a TWS earbud case, we need to carry the Sileton with us close to the mouth and connect to both the smartphone and headphones via Bluetooth. The built-in microphone in the device picks up ambient sounds, which are analyzed by an algorithm based on artificial intelligence on an integrated microprocessor. Thanks to the appropriate algorithms, the voice of nearby people can be transmitted to the headphones, while all other noise is reduced by 25 decibels.

A 1-hour charge of the 230 mAh lithium-polymer battery is enough for 23 hours of use. Currently, you can reserve such a gadget on Kickstarter for $ 89, but so far it is not very successful.
