The sound is pretty good but not as good as a pair of studio headphones like the ATH-M50x. The noise cancellation works pretty well but the ear cuffs are a bit on the smaller side and can get uncomfortable after extended use. For being on the cheaper side of bluetooth noise cancelling headphones, these work really well for the price you're getting it for.
Both sennhiser prints rubbed off the headband after the first two weeks of use. I didn’t miss use them or rub them it just slowly faded. Other than that top quality headphones you get 95% of the bose quality at half the price.
