Processing:
Accustomed well, cable length perfectly adequate. As a cyclist I always use an earplug and put my mobile phone (in summer) in the pants. The cable is long enough to stow the unit in a thigh-leg pocket.
Very pleasant I find the size of the plug. These disappear almost entirely in the ear, as opposed to the original Samsung.
The cable thickness I will keep in mind. As mentioned in other reviews, it looks delicate, but I think that can make up for the quality of workmanship.
Sound:
Here, the usual quality of Sennheiser is clearly noticeable. I'm not a big "hearing Connoisseur" but I can certainly say that my clear highs and powerful bass very well. The latter can provide a small way eating to be strong, but that also depends on the Aufnhame / music style to (keyword DnB / Dubstep). Radio dramas are a delight.
When voice quality so far I could not determine what would have been problematic. My interlocutor could understand me all consistently good and vice versa came with me through the clear sound all from the opposite side of good.
Operation:
Impeccable. Without additional control apps. Volume up, volume, pause / play (center 1x) song before (mid-3x), song back (mid-2x), Voice Search (center long). Everything is there. (I use the Rocket Player)
Features (Here the differences are meant to original accessories):
Above all, the angled plug. I do not understand how to make a headset with a straight connector that are often plugged into the (pants / jackets / hand) -Tasche for equipment ... (well only due to the fact that the accessory break down SOLL).
Furthermore, the mentioned size of plugs that are pleasantly small and set out on a bike not unpleasantly loud wind noticeable, as the original ones.
Conclusion:
Compared to the 3-10 "original accessories" like 35-40 seem expensive, but when you just deal with its accessories with care, not every 2-3 months wants to buy a new headset and want to experience good sound, this headset is, from my view highly recommended. (On the manufacturing side costs a 1: 1 replacement for my Samsung headset ~ 30)
