What's in the Box
They’re great, really great❣️
Very comfortable, good sound and controls, not too impessed with the noise cancellation though, not as effective as higher priced Bose
Ottime cuffie, ottimo il suono e buona la cancellazione del rumore, vengono fornite di cavo per usarle non necessariamente wireless, soddisfatta!
Nice all round choice and perfect compromise of build, sound quality and features. You'll spend silly money to improve on these.
Great pair of headphones! Delivery also good. Sound quality is amazing. Only design flaw in my opinion is that headband goes too far from the head. Otherwise its pretty. Thanks
