Okay, well, I bought the main product (creative zen) about this time last year for xmas, and the pair which came with lasted a grand total of 10 months, failing as the connection between the wires in the nib like bit at the end became disconnected, so no longer played.
So i purchased a pair of these, and yes, they are excellent in my opinion. I listen to metal, and i love the quality of no muffling, no distortion or anything, excellent product in my eyes here. You can remove the small covers if you wish, for a sharper sound if you hear any distortion from them.
They play well, fit in your ear snuggly, and are generally good.
