I just bought a pair of earmuffs for use at home. I can finally sit in the living room while the TV's at a loud volume without being bothered by it.

I slipped a pair of Creatives underneath, and now I can listen to music at the lowest setting on my iPod in a noisy room without being distracted. I can still hear low-frequency sounds in the environment, but they're very muffled. Wish I'd found these years ago.

These ones have hundreds of happy reviews, but I got the other ones because I'm a fan of blue. Both are rated 30 on the NRR scale, which means when properly worn, they reduce noise reaching the ear by 30 decibels. Great stuff.
