The Sony MDR-NC13 Noise Cancellation Headphones are the perfect way to block out ambient noise and be completely alone with your music. Great for when you're travelling, commuting, or at work, these headphones provide an extraordinary listening experience. Designed with battery-operated noise cancellation technology the MDR-NC13 reduces the background noise up to 87.4%.

Using a single AAA alkaline battery (not included) you can receive up to 100 hours of noise cancellation functionality. The headphones even have a convenient monitor switch that quickly lowers the volume so you can listen to a conversation. If you find yourself in a quiet area and don't want to use the noise cancellation function you can choose to let your headphones operate as normal stereo headphones, helping conserve battery power. The sleek compact design is extremely comfortable to wear for long periods and is great to take with you anywhere you go.
