Our take on the Koss RUK50 by Crutchfield's David Brown
Add some color to your music
Koss has long been known for making great-sounding portable headphones that won't break the bank. Their RUK50 headphones deliver engaging sound with deep, powerful bass in a unique around-the-ear headphone. The RUK50 features a closed-back design, minimizing external noise and keeping sound from leaking out and disturbing others, so you can listen anywhere. The padded earcups and headband provide plenty of cushioning for long-lasting comfort. And the lightweight design makes the RUK50 perfect for on-the-go listening with a mobile phone or music player. Available in four bold designs, these fun headphones will keep your head bobbing as their bright colors turn heads.
