ER38-18CL Large Clear 3-Flange Eartips

I bought these to replace the old, stiff eartips on a pair of ER20XS ear protection I'd bought some years back. Brings new life to them just fine. My only complaint is that putting them on was a bit tricky. Not too difficult, but not as easy as when I'd pull off the stock tips for cleaning and stick them back on.
