 SOLD OUT Sony MDR-NC11A/Black Noise Canceling Headphones are an ideal gift for Dad on the go. A nice iPod accessory or MP3 player replacement, these headphones will sound great anywhere, but are especially appreciated when traveling. Active noise canceling sends an out of phase signal that actually cancels unwanted noise. Reduce annoying noise on airplanes, trains and in the car. The Fontopia design includes both active noise cancelling electronic circuitry that detects noise and creates an out of phase wave to cancel up to 70% of unwanted noise, and 3 pairs of earpieces in different sizes to help block out noise. The in ear design is small and sleek, yet provides full sound. A Noise Canceling On/Off Switch is conveniently located on the battery box. The red Power LED indicates when Noise Canceling is operating; when Noise Canceling is off, headphones continue to function for music listening. Extended Battery Life - approximately 60 hours with a single AAA alkaline battery. Airplane adapter included. A gift of Dad can help reduce his stress level when traveling. |
