      Koss PortaPro Features

      The Koss Porta Pro earphones feature dynamic elements that deliver exceptionally rich, deep bass and a remarkably wide frequency response from 15-25,000 Hz to capture every nuance in your favourite movie or musical performance.

      Constructed from mylar, the elements are extremely rigid, minimizing mechanical distortion and ensuring exceedingly accurate sound reproduction. Neodymium iron boron rare earth magnet structures enable the PortaPro to deliver greater volume so you can hear every note, even when competing against the sounds of a commuter train with a low-voltage MP3 or disc player. Oxygen free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. Foam ear cushions provide an open, hear-through sound that lets you keep in touch with your surroundings perfect to wear while running, at work, or while traveling.

      • Comfort Zone setting for a comfortable, secure fit
      • Multi-pivoting ear pads and adjustable headband
      • Collapsible for maximum portability when on the go
      • Includes convenient carrying case
