The CSL 670 I previously had forced too much on the bass and the first thing that comes to mind is the clarity with the simplicity SoundMAGIC.
He does not force on the low and remains steady in the midrange and treble, and it makes all the difference. I'm not an audiophile and I do not think I quite fine ear for the difference between all the little details.
But by purchasing a pair of headphones 35 I thought I had a bigger difference with those 8. There are actually a bass I noticed much more natural, better transcribed mediums, but I did not have the element of surprise I expected.
Maybe I need to go see the very high-end feel a really significant difference. In conclusion the E10 are good-ear.
There is a small bag of simple and effective transport and not tip bad for your ears, I find that some are very poorly calibrated dailleurs very difficult to implement.
Listed for life, if I would not take over the purchase.
