Koss PRO/4S (24měsíců)

The Koss Pro/4S is a professional headphone designed specifically for music fans who use headphones every day. With its brand new SLX40 reference element, they deliver unbelievably accurate, undistorted sound, so the headphones are the perfect choice for studio use. The Koss Pro/4S Studio Headphones come with a 1.4m cable, a 6.3mm adapter and a travel case that protects your headphones while you're on the go.

Key features

  • Designed for studio use
  • D-profile and memory foam earpads
  • Koss SLX40 Elements
  • Removable cable with dual input
  • Foldable for better portability
  • Protective case

Designed for everyday listening

These headphones are made for everyday use, so the shells are made of aluminum, and memory foam ear pads from comfortable leather. The new integrated metal headphone design means the Pro/4S are extremely robust headphones in areas where other headphones often fail.

The Koss Pro/4S has a removable cable (3.5mm jack) that can be attached to both left and right shells for optimal fit. The free connector becomes an output that you can use to connect other headphones, so one audio source can serve more listeners.

Unique design

Last but not least, it is necessary to mention the special D-profile of the earpieces. The "D" shape provides much more comfort than the classic circular shape. Thanks to this design, headphones fit almost everybody. Combined with a padded headband, maximum comfort is achieved even with long term wear. Enjoy the size of these headphones, smaller than the size of the standard studio headphones.
