Different styles of earplugs to try out.
These ear plugs were provided by the seller to me, in exchange for a review afterwards. Four types of ear plugs were included: two pairs are shaped like Christmas trees, one pair like acorns, and the remaining ones are opaque discs.  Ranking from best to worst noise isolation: opaque discs, grey acorns, blue and orange Christmas trees (tied).  The same ranking applies, for greatest to least comfortable. The opaque discs are squishy silicone that conform nicely to your ear canal. The grey acorns are soft, but not as comfortable as the discs. The Christmas trees, i found, provided little noise isolation. The difference between those two pairs, are the softness, with blue being softer than the orange.
