Our take on the AKG K 490 NC

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. "


— Marshall, Crutchfield A/V Writer


these are my teenage son's favorite headphones by far. we have purchased and returned several from best buy and crutchfield and could not find a better pair within our price range. my son has ASD and he has tactile sensitivity so this review may not be very helpful to most people.

Yes. Don't understand why Crutchfield couldn't answer. Great product. I listen to music while doing tractor work. [ FRANK W  Dec 19, 2013 ]
Yes, there is a separate USB cable for charging into the same phone jack input as the sound source. So you can not charge and listen at the same time (not a good thing). [ Duane  Dec 19, 2013 ]
Yes. There are two cables, one for recharging - USB, one for sound. [ ANDREAS  Dec 19, 2013 ]
