They are really cool to look at and have what seem to be very high quality materials, packaging and accessories, but ultimately, they don't seem to outperform my other earbuds significantly enough to justify price. Plus they are very difficult to put in and are pretty bulky feeling. They do seem to physically block out more background noise.
I do not expect this headphone to be great at normal over the head one but I am wrong about this. The minus point for this headphone is quite difficult to wear and not so comfortable at all even it includes several ear pieces in different sizes. Beware if you are picky on comfortability
