The ANC is superb. When I travel on planes they beat my Sony Link Buds S earphones hands down. And they cost me £120. Different use cases I must admit.
Quick story, I used them while on holiday while they were doing building work next door at 5am. Loud skips and building materials. I slept like a baby for 12 hours with them on, a different story. Everyone else was complaining about being woken up.
I’m a wired headphones guy, semi or open back. Sens, Bayer, Focal etc. For the road these Q20 cans are a steal.
