Nice package, not so High Fidelity
I hoped for performance similar to the Etymotic musician's earplug products, which I had previously owned and used extensively. In this I was disappointed.<br /><br />This product has very useful and attractive packaging; the black case with ring can be kept on with keys so you always have these on hand. That is an excellent idea, and does work as the black metal container is small, light, but stout.<br /><br />The plugs themselves are rather difficult to insert fully. If inserted lightly, they only reduce sounds slightly. If inserted more deeply, which takes some effort -- do so with care -- they do reduce sounds more substantially as desired, but this comes with a pronounced roll off in the high frequencies.  So as far as &#34;high fidelity&#34; goes, I cannot endorse these. The level of reduction, subjectively, is about half that of the typical &#34;safety industrial&#34; foam plugs.<br /><br />For tonally neutral noise level reduction, such as for live music or performance on stage etc., I will be continuing to purchase other products that actually do perform that purpose well.
