I buy these headphone two year ago for $ 70 after loose my father 20year old pro4 -lrb- oop -rrb- . my big complaint about the pro4 be that -lrb- the 20 year old one -rrb- be heavy and not too comfortable so I choose the pro3 . they sound great for about 2 month when suddenly one earpiece just snap off the headband . for $ 6 + $ 7 shipping I return for a complete replacement . that be the great part . one year later I be do the same thing again . the earpiece snap off again . I be not abuse these . I be just try to put they on my head . Hindsight : I should have go for the pro4 or another brand that use metal instead of cheap , flimsy plastic . pro : good sound , light comfortable and will not break the bank . con : cheap construction . break very easily . if I could justify the mv1 I would go for those .
