Query: Good noise reduction and features for the price!

I bought these for a NASCAR race and they worked great! They are straight-forward, fit well, and had a nice volume knob and mono/stereo switch built in. They're not light, but I wore them for nearly 3 hours straight with no issues. The audio is decent, but there's absolutely no bass so I wouldn't recommend these for anything but loud situations with just voices (rather than music).
