the pro : these be my preferred headphone of choice . I live in north Dakota and we get a lot of different condition here and I wear these headphone daily . I be very active and sometimes have a tendency to fall down while these be on . the most that usually happen be they get scuff up a bit . after a while the reflectiveness of the headphone do wear off but all in all a decent headphone . another issue I tend to have with headphone be that they be not comfortable because I have gauge up ear . these be the first headphone that I do not have any problem with my earring push into the side of my head and hurt after wear for 20 min . now the con : I believe this will be the best sound quality you can get from `` active '' style head phone . not eargasmic sound quality but very good none the less . while the protection for the cord on the headphone end make the cord last at that connection , the cord on the plug side have a tendency to end up break inside the cord itself . this be my 3rd pair and the last 2 have have this problem . all in all : I highly recommend these head phone for anyone look for a set of durable , comfortable , fairly good quality sound headphone .
