Our take on the Koss RUK40

by David Brown

Impressive sound at a great price

Headphone pioneer Koss has long been at the forefront of producing inexpensive headphones that deliver involving, detailed sound. The RUK40 is their latest triumph of sound quality and comfort at a low price. These unassuming on-ear headphones will impress with their tonal balance and openness. And the cushiony earpads will make it easy to wear the RUK40 for hours on end, for non-stop listening on the go. Available in five colors, these are a great buy if you're looking for comfort and portability in a sweet-sounding set of on-ears.

Highlights:

  • flat, tangle-resistant 4-foot miniplug cable
  • pivoting earpieces for custom fit
  • frequency response: 20-20,000 Hz
  • sensitivity: 98 dB
  • impedance: 36 ohms
  • warranty: lifetime
  • Our 60-day money-back guarantee

    Features

    Overview: The Koss Rukus-series RUK40s are lightweight on-ear headphones. The uniquely designed ear cushions help eliminate ear fatigue, so you can listen comfortably for hours. The RUK40s use dynamic elements for smooth bass and a wide frequency response. The earcups pivot so you can lay them flat for storage or packing in a suitcase.

    Cord: The headphones have a 4' tangle-resistant flat cord terminates with a slender 3.5mm plug. The narrow collar on the plug allows you to connect to recessed headphone jacks or portable digital music devices with hard cases.

    Warranty: The RUK40s are covered by the Koss Stereophones Limited Lifetime Warranty.

    Specifications:

    • Frequency Response: 20Hz-20kHz
    • Sensitivity (dB/1mW): 98dB
    • Nominal Impedance: 36 ohms
