Panasonic's RP-HC700 headphones cancel a whole lotta noise

We can't say they're the most stylish noise cancelling headphones we've ever seen (far from it, actually), but Panasonic's RP-HC700 sure do cancel out an awful lot of unwanted sine waves. In fact, these retro-inspired cans nix 95 percent of surrounding noise, and they'll also ship in both black and white hues for somewhat obvious reasons. Other specs include 40mm drivers, a 10Hz to 30kHz frequency range and 15 hours of noise cancelling with a single AAA battery. If you're into keeping tunes in while keeping -- well, everything else -- out, you'll need to free yourself of ¥20,000 ($237) next month.
