The left ear tip sleeve tube of my ie8 broke. I don't know how it could happen.It seems that it is difficult to fix by glue. Do you have the same experience before?I found some posts that complain se530 and um have the same problem (easy to break). Until it is fixed i need another pair of earphone. any suggestions?I listen to different genres(mainly pop and jazz). My source is iphone. I am also wondering if i should move on and get a portable headphone which gives me better sound and it lasts longer (I believe).
