It's a good start, Etymotic makes some of the most uncomfortable earplugs (the most uncomfortable I've ever worn), they sound fine.. as long as you don't need to lie down or rest your head.

The naming isn't great in the competition, but: Alpine, EarGasm, EarPeace, Loops are significantly better. Recent Alpine reviews suggest a material change - so maybe not them (haven't tried the new ones). They all come in different editions which is mostly about which frequencies they block/allow through.. loop is trying to push the price boundary (probably avoid, especially their "active" line).

All better than basic fluorescent foam earplugs though, easier to use and better sound blocking (the good audio ones allow you to speak/hear voices at close to normal volume in front of a 90dB sound stage)
