Which in-ear headphones should I buy? (MUST BE DURABLE!)?

I've gone through tons of Apple headphones and a few other brands too, but all the brands that I've used seem to break at some point... I'm really only looking at in-ear headphones right now but I'm having trouble finding some that are FOR SURE to be durable. Oh, and the price can't exceed $40-$50. For a very long time, I've had my eyes on the Sennheiser CX300s. But what made me so hesitant was that I wasn't sure if I'd like the asymmetrical cord design and some people have also been complaining about the noise from rubbing/touching the cord. I also found the Klipsch Image S2 headphones that seem pretty popular but I'm still questioning their durability (I like the L shaped jack but I'm scared that one ear might fade out from wire frilling like what happened with my Sonys). I use my headphones ALOT (riding the bus to school, and even sleeping at night) so I need a pair that won't break and at the same time, fit my budget. Any other suggestions are welcome, as well. Please, my current Apple headphones are starting to break at the cord adjuster and I need a new pair of headphones FAST. Keep in mind, the cheaper the better but at the same time, the sound quality can't suck (although I'm not too picky on that). I'm also very lazy and don't like to take the time to put my headphones in a separate carrying case (I usually wrap them around my iPod). *This is something extra but it would also be helpful if you had any tips/recommendations on how I SHOULD wrap my headphones around my iPod*
