I found the over-ear version louder, brighter and coordinated spatial, but also significantly more boring than the on-ear version. The latter was warmer and had a clearer, deeper down reaching (or better perceptible?) Bass, without being really bassy. I have therefore decided to use the on-ear version.
After a few weeks of intensive listening is my conclusion that I know the momentum on-ear has become a sympathetic companion, he, however, my search for a worthy successor for my fantastic (but unfortunately by the predetermined breaking point cable break then gathered much too fast) B & W C5 could not finish , The momentum for the latter it simply lacks even on space and in particular lacking the last ounce of stability even at higher volumes. I tested the headphones to various iPods and felt the handset as a comparatively quiet. The iPod must be almost always turned up to have fun and even then it's still a far cry from the pain threshold. Unfortunately, the headphones occasionally distorted at high volumes. It may be that he strikes up loud to other sources, but as he clearly has the focus because of the remote control Apple devices, I find the momentum construed as too low.
In quieter volumes of Momentum can but very convincing. Overall, the sound is still to be described as warm, although it has tendencies towards analytically here you realize that genes from Sennheiser. Only at the space lacks. The tones are indeed very precisely reproduced (except in the absolute low end), but a localization of sound sources / instruments is not possible. I do not care, because the momentum still sounds very good. Although all sounds seem herauszustrahlen of a point, or mushy mushy sound is never. The greatest weakness of momentum is mE uncleanliness in the bass in some songs that I like to listen to. So I had at Daft Punk's Doing it right the bass completely take out in order to play the piece without distortion can, unfortunately thus losing the fun of the piece. The situation is similar in some pieces of Trentemoller or in some classical organ pieces, in which the momentum capitulated in bass. Operas sound due to the warmer vote of the listener in turn pleasant and singing voices or heavy pieces of pop and rock are never annoying.
Conclusion: With the momentum you get a very good all-rounder, which can be heard without tiring even for hours. In this price range you will be sonically mE hardly find alternatives. So who can live with the weaknesses mentioned above (really suits at a high level) and who at his audiophile expectations (if he or she who since has) makes lighter smears, can find an excellent processed headphones with interchangeable cables and pleasant weight, In addition, also looks good.
Addendum: I have now found my favorite: the NAD Viso HP 20 !!! An absolutely fantastic in-ear.
