These headphones are good for those who love the bass! They are present and even a little too much for my taste; acute apparent shortly. The holding in the ear is perfect with a bit of skill and if you have the size of the ear canal which corresponds to the tips! Otherwise, you will have to cobble together yourself tips based Kiess ball!
After a year of frequent use, the son break (they are too rigid and resent the constraints). He has a lifetime warranty but I have not tested (the shipping costs are for you so in the end I do not think you really be winner).
After testing the two, I find the best Creative EP-630 from a point of view sound and comfort.
