Impressive Sound Quality Is The Ultimate Goal
This item is passive noise isolating, NOT active noise cancellation(ANC), it can’t cancel the noise completely but it won’t drain the battery and damage the sound. As an additional factor of sound quality, it is better than ANC. The closed-back design provides immersive Hi-Fi sound with CSR chip and 40mm driver together. If you care more about Noise Cancellation than Sound Quality, you may consider other alternatives.
