My klipsch is showing tendency of wire slipping out from the buds like this post is discussing about it. I can literally pull the right wire back and forth roughly 2mm to 3mm from the housing cone. Funny thing is that I bought these phones from the bestbuy 3days ago. Although the sound quality is perfect and all, but I'm worried about the future issues that might occur from this wire instability. Does all klipsch s4s' right cable show this familiar problem or is it just me who unluckly picked up an impaired earphone from the bestbuy? I don't mind of returning mine if the new klipsch I exchange shows the same type of problem again. I might've just losing the burned out effect from my existing klipsch. What should I do?
