Very sturdy and looks almost like the one they installed on my boyfriends Trek at the store but for less money. Also like how there is a depression formed into the sole for your heel to go into, so theres not so much pressure being put on it. Good sound and nice quality feel to them. Aún no me baño o nado con ellos, así que cuando lo haga, confirmaré mi reseña. You can feel the bass! It is comfortable to wear for long periods. And 1 more because my friend who is 57 and 185lbs tried it on and it fit her PERFECTLY on the 1st row. I buy the same size for Teva and this new version Katavi 2 runs small - about a size too small. I have had these for a short time but they have been the best investment so far as headphones go, the noise cancellation is right on point and the sound quality is great. I assumed there was a catch on it, so I could maximize the storage without it coming apart.
