Part of what makes the holiday season so special is the way it treats the senses. There's the taste of holiday favorites (yes, even fruitcake). There's the joy of seeing friends and loved ones. And there's the wonderful cacophony of sound, from Church bells ringing, to carolers singing, to pipers piping and drummers drumming. That makes this a perfect occasion to spread the gift of sound to those you love. From headphones to fill their ears with beautiful music to home-theater speakers to fill their homes with high-octane movie action (without completely emptying your wallet), here are some terrific choices to consider.
