For the price an excellent headphones. Compared to a multiple more expensive AKG K701spielt the PX 100-II in the bass too loud, although without rumble and restrained highs. At the very beautiful voice reproduction can not be faulted. The comfort is excellent, the strap easy to adjust the size. The folding takes some practice, kindly the brackets are labeled that only the left bracket to be folded. Should fold too often it is better not because the criticized by several reviewers cable breaks I can understand. The cable inside the bracket is bent when folding two edges and also lacks the plug a bend protection. Therefore, the headphones should not be folded too many times, but already on the go, it is suitable due to the open design-related poor attenuation of ambient noise less. To take along on trips and use in peaceful surroundings, it seems well suited to me.
