31 dB P3E Helmet Mounted Ear Defenders, Black/Yellow - 

For high performance hearing protection against moderate noise levels, use 3M™ PELTOR™ Earmuffs X2. The P3 adaptor in the X series line features the same metal arms as can be seen on the helmet mounted models in the 3M(TM) Peltor(tm) Optime(tm) range. Made of both metal and plastic they offer strength and long lasting durability for the many applications which do not require electrical insulation. Carefully moulded sliders ensure the earmuffs are easy to adjust when on the head. Wide, soft foam ear cushions help workers stay comfortable, while the slim cups offer improved compatibility with other safety equipment. Reducing noise up to 30 dB, 3M PELTOR Earmuffs X2 are colour coded yellow, making it simple to select the correct level of protection from the X series range.
