Pros: Speed Speed Speed
Cons: Feels a little clostrophobic at times
I've been reading a lot about the sm3 having low bass output. These are monitor headphones, designed give a flat response. If you want more bass, simply turn up the bass levels on your equalizer and you will get mindblowing bass.
After a few minutes of fiddling with the equalizer you will realize that it's perfect the way it is.
I really do beleive there is ACTUAL burn-in. Hearing bass-heavy tracks out of the box and comparing it with bass-heavy phones (Panasonic Zirconias with shure triple flange tips), it sounded a little anemic at first. In fact I hated the way they sounded. A month later I did the same comparison and found them to be much better in bass in quality and quantity
The V2 fit is very comfortable. Sits right against your ear.
I've tried a million types of tips but double flange seems to work best (cut the tips off the Shure triple flange).
I've compared these to UE TF10, MTPC, Sennheiser 8s, and none seem to compare.
The only drawback is that it can sound a little "closed in" at times. Ran it through a Cmoy and that seemed to help. I think it would work well when paired with the ALO RX. Gotta start saving up...
