How do they sound, you ask? Well, simply put, they change the sound signature of the headphone significantly. this being our second pair to purchase as the first pair ran very small, the second ran rather large, however, they will do the trick. I will update in a month or so . I have limited space but it fits right in, without looking cluttered. If you dont have a really wide frame, get it! For a short day, they do rub a bit on the back but it is manageable. Would like them better, fit wise if they were a bit tighter across the arch. Problem #1: cheap insole is inserted; it?s not part of the shoe. It fits my feet - they are wide at the toe box, and it is almost impossible to find women shoes that fit comfortably. Sound quality is amazing, noise cancellation is excellent.
