Had bought it with the quality perspective of the brand but it has been proven wrong. Key works perfect. He recommends them w/o reservation. Ill definitely reorder them as long as I continue my serving career. What I liked. What Im doing for now is, Ive cut out the black cone foam from the stock earpads and tucked them into these. Schlussendlich kann ich nur jedem empfehlen den H7, bzw. I bought the green one two years ago. On stock earpads they sound neutral, maybe a little bit on the warm side and lacks some excitement of clarity I was hoping for. I continue to be impressed with the rim sports brand of exercise accessories.
