Headphones are a handy device for silencing traffic, listening to the traffic report, or stopping traffic with a flawlessly executed crosswalk shimmy. Get an aurally pleasing upgrade with today's Groupon: for $50, you get $100 toward TVs, speakers, and home electronics from The Little Guys Home Technology in Mokena.

The Little Guys Home Technology adorns abodes with home theaters and other audiovisual equipment through a dedication to customer service. Rows of obedient Klipsch, B&W, and Velodyne speakers ($99+) line the showroom as valiant audio soldiers that protect and serve by imbuing each note of the Lamb Chop theme song with eardrum-tingling tonal clarity. Alternatively, a set of headphones forge a more direct audio-to-eardrum connection ($29.95+), and the LG, Sony, and Panasonic TVs splash living room walls with sharp, clear, and colorful imagery ($399+). Finally, customers can test home-theater technology in a series of "lifestyle rooms" rigged with realistic interior accessories such as fake fireplaces, potted plants, and unwashed dishes you plan to clean just as soon as this episode is over.
