Purchased these to replace the original earsocks (still amused by this term) on my Crosshair 2.0 sunglasses.  As others have noted, they're a bit long, but that doesn't really matter, and if it bothers you, they can always be trimmed.<br /><br />They are an adequate replacement but they are NOT identical to the original earsocks, which are &#34;fatter&#34; towards the back and thus grip the sides of my head a bit better.  Still, given that the old ones had started to deteriorate and tear, they're an improvement over what I had, and a bit cheaper than buying new glasses.
