I see,thanks for the informative reply.What do you mean by BA unit? Yep i've had it for a mere short year and 3 months,so i doubt its a quality control problem. Nah with what you said it's definitely not a wire problem.  

Pardon my poor command of english.How would recabling or shelling them help fix the issue?I think i might as well try to get my hands on the Mk ll.Thanks for the heads up

Hi guys i need some help! One of the side of the driver for my earpiece has spoiled and sounds way softer than the other working one, what can i do about the situation? Should i go for an upgrade? Also can someone tell me why it the driver has spoiled? I'm no longer under warranty
