Quicker than inserting earplugs (and waiting for them to expand). Bright red and big - they're hard to lose. Put them on like headphones and walk into any tracking session without fear of blowing your ears. Great when you're setting up mics, and the band is warming up. Peltor even makes a belt clip for them! Plus, if you hold two flashlights in your hands, you can look like you're directing airplane traffic. Pick them up at your local hardware store. They come in various models and colors. I got mine at Home Depot for $12 USD.
