I have the same issue with HDJ-X5BT. The same plastic part that connects the earphones body to the headband is cracking after a few months usage. I went to the seller, they replaced the complete unit, then the new one started to crack at the same exact place on both sides. I always take cake of my equipments and i am very disappointed about this bad quality parts. I will have to contact again the seller or distributor, i don't want a third replacement that will break again and again.... More to come!
