The sound was decent, but I returned for the "NewFantasia Replacement Earpads Compatible with Audio Technica ATH-M50x, ATH-M40x, M50S, M20x, M30x, ATH-SX1 Headphones Sheepskin Leather Memory Foam". I have even run several blocks in these no socks when i was pressed for time and had no problem, no trips, no blisters or burns or anything like that. I work 8 hour shift. The mic on it is even good. I could have ordered a large. Ich habe eine 42, und w11 bzw. 5 mm jack and place it to an acceptable range. I havent gotten any blisters at all. The bottom case fits snugly and never come out. At least with TEVA, the velcro hold the strap in place all day without any give.
