Feb, 2016

Product Specifications

Use these headphones to block out noise, listen to music, or do both at once! Sony Noise Canceling Headphones reduce outside noise by more than 70%. Listen to Beethoven without being bothered by the symphony of your neighbor's buzz saw. Take in the latest Salsa sounds on planes or trains. These magnificent headphones feature a "noise canceller" on/off switch (in case you need to hear what's going on around you) and a headband that folds for easy storage. It reduces noise by 70% (10dB) making it ideal for travel - it gives you peace and quiet on planes, trains, buses and cars. It is also ideal for outdoor use when you are gardening or on a noisy street. Its noise canceling circuit actually senses outside noise with built-in microphones and sends an equal-but-opposite canceling signal to the headphones; cancels noise from 50Hz to 1, 000Hz, with a maximum of 10dB noise cancellation in the critical range from 100 to 400 Hz - where the human ear is super-sensitive. Enjoy its closed headphone design that gives you greater isolation from outside sound. Its folding headband and pivoting earpads make for easy storage in a backpack, briefcase or purse improving their portability.
