Silence noisy environments for travelling comfort. Take the noise out of noisy planes and accommodation with Noise Canceling Headphones. These comfortable and compact headphones let mobile professionals travel in peace and quiet. A built-in microprocessor analyzes background noises and creates an inverse sound wave that cancels the offending sound. Engines, fans, snoring, and other low frequency annoyances virtually disappear, leaving the traveller free to work, sleep, or listen to music in blissful silence. The Philips HN5500 noise cancelling headphones feature: - 75% noise cancelling - compact electronics eliminate unwanted external noise by up to 75%
- Slim lightweight controls - a slimline control box located in the headphone cable provides convenient volume adjustment and ON/OFF control for the noise cancelling feature. A bright power indicator also provides a reminder to turn the product off when not in use to ensure a prolonged battery life
