Product details

The original and legendary Koss Porta Pro is the classic among mobile HiFi headphones. The Porta Pro impresses with excellent sound quality, featuring a sound rich in deep bass and a remarkably wide frequency response that ensures detailed playback of various music styles. Once worn, the lightweight headphones with their movable ear cups quickly become forgotten thanks to their great comfort. The comfortable ear pads guarantee a pleasant listening experience on the go, even on long journeys. Aside from the metal headband, the headphone elements are made of Mylar, making them very durable. This minimizes mechanical distortions and ensures extremely precise sound reproduction. When the Koss Porta Pro is not in use, it can be folded up (to about 5 cm in diameter) and conveniently stored in the included carrying case.

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.

    Endlich ist der Porta Pro in der Apple Welt angekommen. Er stellt in der Tat eine Bereicherung für die Apple-Devices dar, sowohl seitens der gebotenen Klangqualität als auch des Tragekomforts.

    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.

      Nicht nur wegen der 80er-Jahre-Optik: Diesen Kopfhörer liebt oder hasst man. Die Verarbeitungsqualität ist im Vergleich zu den hier vorgestellten Modellen unterdurchschnittlich, dafür zaubert der Bass auch nach Jahren noch ein Grinsen ins Gesicht des Besitzers.
