love them.
These are great for my purposes - which is to wear them while watching kids' sports in gyms full of whistles and screaming girls.  The attenuation of loud, harsh noises is good yet I can still converse with the person next to me.<br /><br />Comfort is very good and the aluminum case is excellent. I like these plugs much better than the Planet Waves PWPEP1 I bought at the same time.<br /><br />Note that I'm not evaluating them for acoustic fidelity in a music setting, only as hearing protection in moderate environments.
