Okay
I like these Zilly ear plugs okay.  They do a good job of making painfully loud events bearable and not painful.  I got them after going to a concert several months ago that was so loud I couldn't enjoy it.  These will be effective to avoid that situation next time.  As far as fidelity and clarity, they're so-so.  They are better than a pair of foam earplugs that just muffle and dampen everything, but they're not noticeably great on clarity and the claims of high fidelity seem exaggerated to me.  Overall they're good for sound reduction but only fair on sound quality.
