Koss goes camo

Headphone pioneer Koss has teamed up with camouflage designer Mossy Oak to deliver a unique line of headphones that are certain to attract attention, or possibly keep you hidden. The KMO20 delivers bold sound from a rugged design that's as tough as it looks. The large earcups completely cover your ears, and the closed-back design helps keep external noise from distracting you from your music. Soft padding on the earcups and the flexible headband ensure comfort for long periods. Sturdy yet lightweight, these headphones are great for outdoor use, especially given their Mossy Oak makeover.

Just what I wanted

I called to find headphones to cover my ears while on my riding lawnmower. I didn't want to use my pricer headphones but wanted something for outside use. Extremely comfortable, keeps out most of the noise enough so I can still hear a baseball game. The camo is very cool too. Thanks Crutchfield for the two day delivery.

Pros: Very comfortable, good sound, camo looks great.
