3M - Peltor earmuffs/noise cancellers. I got two pairs of them, one next to the desk, one next to the bed. Anytime there is any noise that I cannot control, I put these on and (almost) everything goes away. After 30 seconds I only hear my heartbeat, and that 'goes away' after 1-2 minutes giving me (almost) total silence. At $20, it is the best one I've tried. It is not 'active' (mic filtering & speakers), it just has good foam tech.

If you get used to the 'weight' (not that much) they are also great for your meditation time.
