The transverse inner diameter of telescopic head beam shall not be less than 150mm, and the transverse inner diameter of non-telescopic head beam shall not be less than 165mm; The expansion and contraction amount of telescopic head beam is about 25mm on one side. The vertical inclination angle of elliptical earmuff is about 15-16. Ear pad thickness over 25mm is easy to collapse; Consider increasing the rotation joint of earmuff to improve the fit; Pay attention to the left. The above personal experience should be combined with the actual situation
