Good first impression, very low profile.
Orchestral musician with more than a decade of professional experience. I only just received these so I haven't tested in a loud band setting, but compared to my Etymotic plugs these seem very similar in terms of how much they cut and what the resulting sound is like. Very soft and comfortable, and much more discrete than the Ety Plugs, however the tradeoff is that they're a bit more tricky to remove from your ear, so they're not as convenient if you need to quickly pull one out for a delicate passage.
