Active Noise Cancellation Headphones with Volume Control

Koss QZ900 noise cancelling headphones will create less reason to turn up volume and overdrive the tiny amplifier in your portable electronics. This means greater efficiency, less distortion, deep rich lows, and sparkling highs.

Unlike most other noise cancelling headphones, QZ900s play music with or without the active noise cancelling circuit engaged. A handy removable cord features an in-line volume control, and one standard AAA battery provides approximately 50 hours of active noise cancellation.

Features:

  • Active Noise Reduction
  • Cord unplugs for wire-free passive and active noise cancellation
  • Folds flat for portability
  • Carrying case included
  • In-line volume control
  • Koss Limited Lifetime Warranty
  • Revolutionary Active Noise Reduction (ANR) headphone system reduces harmful and annoying low frequency sounds in noisy environments
  • Closed leatherette ear cushion for added passive noise reduction
  • Cord unplugs to enjoy passive and active noise cancellation wirelessly
  • Straight single-entry 4 foot cord with in-line volume control
  • Fold flat for portability; carrying case included
