A set (2pcs) of precut replacement foam pads for most any ear defenders. Tested to be a perfect fit in Sordins and Peltor models, these should work equally well in pretty much any ear defenders.
Replace those old dirty, smelly foam pieces with a new fresh set at minimum cost. These foam pads are pocketed on the back side to allow space for speaker units as used in electronic sets.
The dense foam offers excellent sound damping and the black colored surface treatment increases durability of the foam pads.
