Left Channel, y u no keep working?!

Today marks the fourth time in the past two months that I've encountered a faulty left channel in my audio device. First the one on my Porta-pro headphones gave out, next the replacement headphones just had a defective left channel right out of the box (luckily I was able to return it very easily), then my laptop's audio jack stopped outputting to the left (ok this one was totally my fault), and now my general-not-meant-to-be-used-anyway earphones gave way. Why is it always the left channel?! It's not like I listen harder on that side or something.. Whatever, guess I'm going to go see what's on sale after school today. My wallet will understand >_>.
