Query: outstanding sound in a small package

I have to admit I was curious as to what difference the double woofers would make in earphones and I was quite surprised by the base response and range of the 530s. I also have to admit that I have a pair of e4C and they are put together a bit more ruggedly than the 530s - I miss being able to change and clean individual parts although I have never replaced anything on my original e4C - the 530s are just a step up in music quality but the sound stage is impressive especially for such a small package - and I'm actually starting to hear different parts in the same recordings I used to listen to with my old earphones that I didn't know existed before ! Definitely worth getting if you can afford them, it's worth the money is you're serious about your music and the sound isolation is great !
