Gran producto

Muy feliz por esta compra. Una gran marc.

p good, but something to keep in mind for big-headed people!

Great headphones for the refurbished price! ANC as well as natural noise isolation is great! Wonderful! Sound is a bit muffled or bass heavy to my taste, but the eq app helped out with that. These can get a bit uncomfortable though, if you have a big head like me. This is due to them squeezing a bit hard on my head, but without that squeeze there would ofc be more noise-bleed. Something to consider, but still a great product.

Great headphones, but with a software "feature"

Sound quality and ANC are good. Controls, features, and microphones are fine. But the inability to turn off the sidetone on windows is very irksome.
