With the Porta Pro Wireless, the legendary Koss sound quality can be enjoyed wirelessly. Koss has successfully transferred the sound of the classic Porta Pro, which has been on the market since 1984, to the Porta Pro Wireless. The open design provides a beautiful spatial sound with fine highs and voluminous bass. With the Porta Pro Wireless, you can perceive sounds from your surroundings, ensuring you stay safe on the street and don’t miss important announcements on the train. Despite the open design, your music keeps the environment almost undisturbed. Thanks to its ultra-light and airy design, the Porta Pro Wireless is extremely comfortable. You hardly feel like you’re wearing headphones. The battery, Bluetooth unit, and remote control are integrated into the neck cable. This also positively influences sound quality, as any electrical component in the ear cups negatively affects acoustic performance. The clamping pressure of the two ear cups can be adjusted to your personal preference using a slider. With a single charge, the Porta Pro Wireless lasts an impressive 12 hours. The headphones can be folded compactly for space-saving storage in the included carrying case.

Der Klang lässt an die 80er-Jahre denken. Damals war der Porta Pro eine Instanz in Sachen Walkman-Sound; Koss schafft es mit dem Wireless, dieses Gefühl ins neue Jahrtausend zu transportieren. Insgesamt warm abgestimmt, überzeugte der kräftige Tiefbass mit Druck und Präzision. Pegel lieferte der kleine Bluetooth Amp auch genügend. Wer den Koss-Sound mag, bekommt alles, was er braucht. Klasse!
