The headphones that came bundled with my W800i sound great but the left ear plug keeps falling out. Looking at them the right plug has more than twice the length of cable than the left side. So it must be the short left hand side cable that is causing the problem. There is a cable splitter but it can't be slid up and down the cable to adjust the length of each side. Are mine dodgy or are they all made with a right cable more than twice as long as the left? If so why? Me no understand! Cheers.
