Noise cancellation works like a charm, though there is a slight hissing sound present in the background - this, however, did not diminish the listening pleasure

Surprised how well the noise cancellation works.

The noise cancellation only works sometimes

Noise cancellation was excellent, and sonically superior to my old Bose QC25 with the added option of still being able to use them without battery power (and without active noise cancellation.)My major complaint is the non-standard chargng cable

These are on-ear headphones, so the passive noise cancellation was not very good at all.

Very good audio quality and excellent noise-cancellation, but they can get pretty uncomfortable if one wears them for over an hour.

What is more is that these things are puny, tiny, annoying things to wear and the noise cancellation is a joke.

This held me back in purchasing this headphone at first, after all, I would like to listen to my music as clear as I can for a decent price
