I had issues with my X3s that stopped working, so I got X4s about 8 months ago and now the left earbud isn't working correctly. It happens when cord gets moved - when I'm holding still I can get it to work correctly. Otherwise its fuzzy or cuts out completely until I move the cord and get it working again.
I've tried cleaning and resetting the earbuds and the problem still exists.
Anything else to try or is this pair defective too?
