RokkaMan:
There have the strongest, deepest, clearest bass you will ever hear from earphones. They have a downfall - the material covering the wires sucks - you can hear every rub and slide between the wires and your clothes, and since i kept yanking them out of my ear instead of grapping them by the earphone itself, the material pulled off and i was left with a useless pair of phones I paid £30 for. Customer service was non-existant.
If you're careful with your phones, you will not find a better pair for rap/hard rock/electric/dance. Otherwise, take a look at the Sennheiser cx500s instead.
Thanks for this kind of feedback on a product mate, makes it a lot easier to read a good review when deciding to buy an item.
