JVC's no stranger to noise-cancelling headphones, but their new HA-NCX77 have that streamlined in-ear appeal and effectiveness that traditional muffin-top 'phones just can't swing. A secure fit in the ear blocks ambient sound while more intrusive background noises are reduced by up to 80 percent (more than 14dB at 120Hz). The power supply looks manageable enough, has a mute switch in case you quickly decide you need to hear something, and takes one AAA battery that provides 70 hours of juice -- and at a suggested price of $79.95, you can actually treat your ears to the sound of silence without zapping your savings.
