I tried the medium which are pre-installed on the earbuds and they seemed a little big, but the small size wasnt big enough, so I figure I just have to get used to the medium size with a little bit of tightness. Son realmente cómodos, se pueden usar casi en cualquier contexto: en agua, en seco, si hace calor, para el trabajo, para casa, la piscina, la playa, con el pie desnudo, con calcetines. The biggest problem is one of thewall brackets was not manufactured correctly. The only problem for mine is the wired version has a loose scroll, but the wireless doesn?t; most likely a rare issue (hoping anyway). Size 12 fits perfect. Like litterally tilts to one side and then the plastic frame cracks and the whole thing bends itself like it has no frame at all, then the poles will tear through the canvas and it will collapse in the middle of your room. I love my new speaker from Bose. I purchased this along with the matching coat rack with cubby holes. Super comfortable! After extensive research and reading a bunch of reviews, I settled on purchasing these foot cushions.
