I already had a headphone Wesc oboe, which I found good, but cumbersome and that was anyway ears hurt after a while. So I was looking primarily a foldable headphones and compact. The headphones AKG k450 is prime for it, it folds and holds no worries in a pocket or a handbag. Its level, no complaints, just pronounced on the low but with the equalizer, arrangements are made and it's really not bad. It insulates from the outside. Very light and really comfortable, no pain in the ears. A bit noisy, I think we still hear enough from the outside, which is a bit annoying in the train for example.
Nice design, quality storage bag and strong, spare cable supplied. No complaints.
