Maybe the best of its type, but definitely cannot be considered high fidelity
Although these were supposedly designed for loud music, and promise to &#34;not deform the sound&#34; , they definitely do not attenuate the entire audible band equally. I tried them with headphones on and found that the higher frequencies are attenuated much more than the lower frequencies. Unlike &#34;dumb&#34; fiber or foam earplugs, these do let some of the highs through, but the overwhelming passage of the bass frequencies eliminate any possibility of hearing a reasonably flat/balanced sound through them.<br /><br />To their credit, these sound no worse than any other brands of passive high fidelity ear protection I've tried. They just aren't much better either.<br /><br />Oh, one more quibble: these will not fit if you have relatively small ear canals. I struggled for 10 minutes each to get them in.
