Das Ton ist super, der Sitz auf dem Kopf passt perfekt und das ANC ist gut (nicht sehr gut)! It wasnt easy to install for us but thats because of our cabinet set up, nothing to do with the product itself. The left one has been totally fine, which is why I think its just my ears. Definitely worth the buy - these are well made, have great sound, and are the right price. They are warm, extremely soft and fluffy. I used this to build an entire road bike. Just beware that curled paper can cause jams. but theyre very very comfortable, and well made, and that is number 1 to me, but I also like cute ones and this one fits the bill, I just wish they had more colors to choose from! The correct app is dependent on what model of headphones you have. WARNING: Since it is so large, order a case with it so if it falls out of your pocket, you dont damage your phone.
