Last lot I bought were the CX300 II ones. I don't know if it's because I try and take care of them -to avoid the very issues you identify- but they tend to last a long time. In years as opposed to months.
The current model has a beefed up jack bit which will resist the problems.
They are comfortable and they suit me as they have asymetric earphone lead lenghts (prob not describing it well) which I like.
I tend to buy Sennheiser earphones.

I think the sound is really good too!
