Product Description
The Jabra C820s stereo music headphones are specially designed for music lovers who want to make the most of their music wherever they are. The Jabra C820s are high performance headphones that deliver full-range, compensated sound through high quality speakers guaranteeing premium audio, straight from your mobile phone or other music source. Hear the music, not the noise thanks to one of the best ambient noise cancellation systems on the market. The headphones incorporate Active Noise Cancellation technology, offering one of the best ambient noise cancellation systems available today. So, no matter how noisy your environment is, you can still enjoy your music undisturbed. How does Active Noise Cancellation work? Anti-noise is an inverted copy of the noise itself. When anti-noise is combined with the original sound disturbance it results in a lower level of noise perceived by the human ear. The Jabra C820S comes with all the connections you need to use it in virtually any environment. For use on the move, the Jabra C820s folds flat for compact and easy transportation. It comes equipped with a standard universal 2.5mm jack for mobile phones and a 3.5mm jack for music players. For use in an airplane, the flat-pack carrying case also contains a 2-prong airline adapter. For use at home, a 6.5mm audio adapter is included, or you can use the standard 3.5mm jack. Note: These headphones are nearly identical in performance to Bose QuietComfort headphones for a much lower price!
