Active noise canceling and a compact design make these headphones ideal for travel.
AKG's K 490 NC ultra-compact folding headphones pack a surprising sonic punch — delivering your music with warmth, clarity, and deep, rich bass.

Their soft, on-ear cushions and padded headband provide comfort for extended listening sessions, and give you blissful peace and quiet while you travel.
Enjoy your music wherever you roam
The K 490 NC's built-in rechargeable battery provides up to 40 hours of noise-canceling operation per charge. You can charge up using the supplied USB charging cable and one of your computer's USB ports. AKG's patented folding design allows these 'phones to collapse down to a super-compact size for easy travel. They'll connect to virtually any portable audio device with a mini headphone jack, plus you get an airline adapter, so you can plug into in-flight entertainment systems and block out engine roar. A handy carrying case stores the headphones along with all the included accessories.
From our staff review of the AKG K 490 NC
"The '490 headphones have me thinking that on-ear is going to be my "go-to" style for cardio at the gym. And I liked them just as well working at my desk. These are comfortable, good sounding headphones that deliver spacious sound to the music you want to hear and a decent blocking out the noise you don't. "
