JBL Reflect Aero TWS

ANC utilises more advanced technology to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) giving 0 resulting in a reduced level of noise.

The Devialet Gemini 2 have ANC allowing you to listen at lower levels of volume, good for your ears since you don't need to crank up the earbuds volume to outcompete background sounds.
