Now, I also like the Beyer DT770 Pro 80 ohm, the Thinksound ON2, the Senn 569, the Meze 99 Noir, and the M40x. It?s bigger than I expected. The reason I?ve only given them 4 stars. I have had this keyboard for about a month or so now with zero issues. From the beginning charging function was bit temperamental (bit fiddly but made it work eventually) now it completely unreliable and will not connect to docking station properly to charge 90% of the time. Outside of that, I can list 100 positives. The only issue I had was the cord started to start to pull out of where it connects to the headphones because I regularly drop the headphones and accidently yank on the cord, but I got some gorilla hotglue sticks and a hotglue gun to reinforce the connection of the cord up into the headphone and that has held super solid for a long time now. They fit but I would say size up as kids grow so quickly and they?re a bit on the small side. Ich bin mehr als zufrieden! Wegen der besseren Gewichtsverteilung ist die Standfestigkeit idealer,wenn man das Hinterrad benützt.
