Query: Throw away 'expensive' headphones

Bought these earbuds in early June, broken by late September. Used 3 or 4 times a week while sitting on a bus, for about an hour a day. Now, only the left side plays. The 'lifetime warranty' from Koss requires that you send them back with a check for $9.00. Pretty sad when the headphones cost about $12 shipped.The reason for the 2-Stars is that they sound quite good when they work. But, since they only last about three months, paying $48/year is expensive, and a bit too rich for me.Got some Skullcandy phones to try. They sound almost as good as these, and I hope they last more than 3 months.
