Unfortunately, K7XX does not offer great passive noise isolation. Even though the headphone has large and dense ear pads, they are outfitted with velour or suede-like material which has below average noise reducing capability. Additionally, the headphone’s open-back design gives way for the sound to travel out or the environmental sound to get in. so, if you want to use these headphones effectively, you need a quiet room like a studio or a noise-free home environment.
