Designed using the technology from another popular Koss model, The Plug, the stereo earbud features a dynamic element that is positioned just outside the ear. The element is connected to a tubular port structure that is inserted on a soft expandable cushion into the ear canal. Soft foam “memory” cushions expand for a custom fit to improve isolation and enhance deep bass and treble clarity. Utilising the fit and mechanical design of the headphone to reduce noise is known as Passive Noise Reduction (PNR).

While the ANR circuit reduces low frequency noise, the PNR reduces high and mid frequencies so music and voice can be heard in absolute clarity.

The result is double noise reduction and maximum sound performance all in one complete product.
