Query: One bud works, other does not.

What a huge disappointment. I'm not sure how people give this product a 3,4, or 5 star rating. The second day I got these, the left side did not work.This is the third pair I have bought and the other two worked for much longer, but the SAME EXACT thing happened.I thought it was me being rough with them, but now I KNOW with a certainty that it's not me.no thank you, I'll just buy Apple's iPod headphones from now on. They last forever.
