   Store: OfficeMax
   Price: $12.99 with $9.95 s&h
   Lowest By: $17

   Is It Worth It?: Noise-canceling headphones offer the perk of allowing you to listen in loud environments without blowing your ears out. And these headphones won't blow your wallet out, either: even with $10 shipping, they're the cheapest pair of TDK noise-cancelling headphones we could find by $17. These headphones feature active noise canceling, soft ear pads, swivel ear cups, and an airplane adapter. They work by pumping ambient noise into the headset, but flipping the phase of the bad sound waves so that they knock each other out.
