Some of the earmuff offered here are almost exclusively rated contactors. Therefore, I would like to speak working for the people's. The sound can be compared to a normal workshop operation absolutely sufficient and with common ear muffs. The sound quality is definitely better than in most stereo headphones and even at low volume levels still very good. The (for me) annoying workshop Radio is no longer perceived, hurray! If you do not exaggerate with the volume, even communication with colleagues is still possible. That would be the only point I would disconnect the headphones produce an absolute separation from the outside world at full volume for me. Nevertheless, I give full marks because the volume control in the user's responsibility is and setting a low maximum volume eventually would indeed be a point to complain. The bottom line, for me the perfect solution!
