A:Answer I can happily say that these are durable (from my experience) I had them for 3 months and constantly barraged them with daily workouts, sweat, and even sleeping on top of them almost on a daily basis. Despite all that, they held up very well. Granted each individual product is gonna vary in terms of durability, but Bose has been very good at quality assurance. If in doubt, just buy them and return them if you are not satisfied with how they hold up for you. 15 days (normal return policy) should be more than enough time for you to decide if they are a keeper or not.
