I do not know if this is Pro. This is not a typical V or flat, you can feel the bass boost, but the treble is slightly recessed. In some way it would fit into IE8 sound signature, so maybe this is the Pro version.
If the sound was faster for sure it would be a better earphones. And flat not equal boring.
Hm, okay. I'll restate my post.
Wait a second, if you don't know if yours is the Pro version...then what is it? XD
The Pro version, to my recollection, was ordered by Bhazard and a few others upon request.
If those are the Pro versions, I'm surely not going to like its slow sound as you stated.
Bhazard, where are you?
