As the title says, which one would you recommend? Up until today I had Cx 300 II but I managed to break them using nothing but my stupidity. But they've been awesome because of sound quality and durabilty. But, the Sony earphones have an appealing feature:flat cable. And I've also read the the sound is very good. So, as you might expect, I'm in a bit of a dilemma and I hope you can help me. Thanks.
