Product details

The original and legendary Koss Porta Pro is the classic among mobile hi-fi headphones. The Porta Pro impresses with its excellent sound quality; with a sound rich in deep basses and a remarkably wide
frequency response, which ensures the detailed reproduction of a wide range of music styles. Once put on, the lightweight headphones with their flexible ear cups are easy to forget thanks to their great wearing comfort. The comfortable ear cushions guarantee a pleasant listening experience on the move, even on long journeys. Apart from the metal bar, the headphones are made of Mylar and are therefore very stable. This minimizes mechanical distortion and ensures extremely precise sound reproduction. If the KOSS Porta Pro is not in use, it can be folded up (to a diameter of approx. 5 cm) and stored in the included carrying bag to save space.

Die Klangeigenschaften sind gemessen am Preis überaus solide, wobei das Gerät sehr kompakt gefaltet werden kann. Die Headset Funktion funktioniert ebenfalls gut dun preislich ist das Modell sehr attraktiv. Zudem ist der Sitz fest aber nicht unbequem.

Der Koss-Kopfhörer ist sehr leicht (70 Gramm) und zusammenklappbar. Im mitgelieferten Kunstoffbeutel passt er locker in die Jackentasche. Über Schiebeschalter an den Seiten lässt sich der Anpressdruck einstellen.
