I currently own a pair of Klipsch s4's that I've owned for around 5 months and I'm just checking if my problem is an eligible reason to receive replacements before I go try calling customer support. Recently the audio jack/plug for my earphones has quit working, I know the problem's in the audio jack because the sound only comes clearly when I push on it slightly. This happened on my last pair but I didn't bother trying to replace them last time. I'm certain that this is not from misuse. Also, my other problem is that I don't have the original packaging the earphones came with anymore, does this mean that they'll be refused for replacement? Thanks.
