What's in the Box
Habe es als Geburtstagsgeschenk für meinen Mann bestellt, der mehrere Stunden pro Tag mit Kopfhörern verbirngt (beruflich und privat). Ergebnis :: er ist begeistert vom Klang und der Handhabung. Auch trotz einer Körpergrößevon 1,98 cm und einem entsprechend großen Kopf, passt der Kopfhörer super. Da es ein Geburtstagsgeschenk auf den letzten Drücker war, war auch die pünktliche Lieferung wichtig. Alles toll geklappt. Gerne wieder
le cuffie sono davvero ottime ma riscontro problemi quando cerco di connetterle al telefono e quindi non posso sfruttare a pieno le loro potenzialità.
Sono costretto ad utilizzare sempre il cavetto.
The buttons layout is a bit cumbersome. I had read this from different reviews but didn't fully understand it till I tried the headphones.
There is absolutely *no need* to repeat forever "lost connection" once you walk away from a device and lose the connection, forcing to a full turn off and on of the device to make it go away. This is extremely annoying. Please fix it with a firmware update, or it will drive me crazy (as well as many other according to what I read on the internet).
Otherwise it is a very very nice product, especially for the competitive price!! I would buy it again.
these are one of the best pair of headphones i’ve owned but i’ve run into problems with them. After i switch them off and want to turn them on again i hear a loud buzzing noise sound from them. I also hear a loud ringing noise if I even apply a little pressure to my head when laying down sideways. Apart from that the headphones are good considering the price but the noise cancelling isn’t as strong as advertised to be.
