I have own this pair of headphone for a year now and I would say that these be worth the purchase . I be write a review now because after a year of use , the right headphone finally snap off . even consider that , these headphone remain worth the price . pro - great sound quality ; Clear and handle bass really well that can otherwise be inaudible . - tight ; if you be in a loud environment , these will definitely make sure that no outside noise leak in while listen . - cord ; very long , conveniently wrap around , and very unobtrusive when wear the headphone . con - headband strap be incredibly flimsy ; the plastic inside of it appear to crinkle and crack to adjust to you head 's shape in a unflattering manner . the strap 's connector to the headband be make of fiber and very prone to twist . this cause I to fumble around with they every time before wear to twist they back into place . - screw be not tight ; somehow , one of the screw on the left headphone fall out a while ago . the headphone manage to remain attached , however . - uncomfortable after heavy use ; I use my headphone daily for many hour at a time and I experience soreness after remove they . - ear pad ; very prone to collect strand of hair and debris and be not easy to clean . they do remain removable , however , as I have remove and place they back on a few time before . - durability ; if you plan on use you headphone frequently for extended period of time , I do not recommend these headphone because of they cheap build and discomfort .
