Damit ist dieser Kopfhörer für mich der letzte von B&O. These can get loud enough to cause ear pain so be careful with your hearing. I measured mine and they are 5. If I try to listen to something on my phone while my wife is playing with her sister, and my phone is turned way down to the point I can barely hear it and is about 4 feet from her mic, her sister will say she can hear it. Identical to picture. Love the colours and style. This is an extremely important feature for any Bluetooth headset I use. It solved the problem of them falling out of my ears but they still hurt my ears. Hes 3 and has no problem getting them on and off and puts them through a lot with no issue. Ive heard of this issue before from many people online but figured if it was even reasonably consistent then I wouldnt mind keeping a lens that is sub $300 and is so specialized that I would only use it sparsely anyways.
