Last a long time. Ich hab eine sehr schlanken Fuß aber die sind schon recht eng. Good quality, pretty comfy,They are slightly loose fitting which makes them not something I?d wear if I was going to be in them for more than a couple hours. The pockets are slanted, and do not really open up to accommodate items other than a shoe toe. With his wide feet, I feel happy we could find anything to fit his unusal feet. The sound was decent for the price, though I dont know about the noise cancellation. Amei minha compra, meu note 9s The medium tips worked alright, but when I switched to the large it was a world of difference, both made me feel much more secure of my earbuds ability to stay seated. Ive also received compliments from students and colleagues alike. I had already bought one of those and I ended up buying a second one.
