Las compre 10w, me quedan muy bien, aunque un poquito ajustada . They are very comfortable since there isnt anything going into you ears. A little too silly perhaps, but strong and willed nonetheless. der Bügelverstellung und die drehbare Achse der Ohrmuscheln aus Metall gefertigt. Ive tried a few wheel on trainers, and they all had to go back due to the insane level of noise they produce. Its like having a mini Gameboy! The footbed is very cushioned though. They fit like a 9 in regards to length. The maximum volume may not be loud enough for some people, but it is for me, and bonus, I get no sound distortion even at max. But even without wheels I love this little rack.
