ive not used that particular pair of technics, but over technics headphones i've used before have been great, comfy, sound nice and no distortion.
dont know how reliable they are though.

as for the senheissers, still one of my favourites, again, sound nice, no distortion, can feel a bit uncomfortable though, but the big plus point is being able to buy replacment cables, headbands etc.

never used the others
