Turn on the FR compensated feature, because otherwise the charts look way different from what you see on other websites like goldenears and innerfidelity.
This is the same comparison with it on, though I was talking about the over-ear, apparently the general consensus here is that the Momentum on ears are rubbish.
These are 2 pretty different headphones. I actually demo'd the momentum's for 1 song or so, and they only had 1 rock song I could listen to, Foo Fighters - Walk. It sounded alright but the vocals were front and center, not the guitars, so overall I actually like the VMODA M100 more for this song, if it wasn't for the recessed lower treble it would be perfect. The Amperior has more of a mid-treble spike than the M100 however, making me worried if it is going to eat my ears out like the A900x does.
