Has Active Noise Cancellation (Noise Control)

✓
Devialet Gemini 2 ✓
ANC utilises advanced technology to actively counter noise. ANC works when, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) then adding -1 (counter sound by the device) to make 0 hence "diluting" the noise.
The Devialet Gemini 2 have ANC enabling you to listen at lower volume levels, good for your ears as you don't have to crank up the earbuds volume to outcompete background noise.
Bang & Olufsen Beoplay EX too have ANC making either of the devices ideal for flights and rush hour commutes. Each work with different noise cancellation types, pick the mode that suits your travel or that enhances your chill time.
