I've used both the Sony WF-1000XM6 earbuds and the Bose QuietComfort Ultra Earbuds (Gen 2) for months, and they're the best of the best when it comes to active noise-cancellation power.

I wore Sony and Bose earbuds in a noisy coffee shop(Image credit: Brady Snyder / Android Central)The first place I took the Sony and Bose earbuds to was my local coffee shop.
