The sound is similar to the the EP630, so easily bassy but without equalizer quite enjoy. So fine resolution and fully as the SE-215 are of course not, and the processing is clearly cheaper. However, the cables are much more stable than the EP630 and the remaining processing appears solid and durable. However, they are easier and more practical than the SE-215 and not amplify the sound of footsteps and so much. The cable clamp, with which you can fix to the clothing, is a useful extra, and also the angled plugs like better than the just the EP630 me. There are not the usual 3 sizes of silicone earplugs, but equal to 4, which increases the chance to get an optimal size.
The only shortcoming is the fact that they protrude relatively far out of the ear. Thus, for example, they do not wear, if you want to listen to music lying in bed on the side. But for that I have my first class SE 215th
Conclusion: Recommended as affordable InEars for mobile use very - at least when they hold as long as the processing is expected. I had only a few weeks, but first'm optimistic.
