Koss Porta Pro On-Ear Headphones with Detachable Cord and Collapsible Design

Since its introduction in 1984, the Porta Pro has endured as one of the most recognized headphones worldwide. For over four decades, this legendary design has captivated listeners with its breathtaking high-fidelity audio performance.

Delivering a frequency response of 15-25,000Hz, the Porta Pro immerses you in deep bass, crisp highs, and a remarkable midrange - replicating the excitement of a live musical performance. This blend of high-fidelity audio and nostalgic style has solidified the Porta Pro's status as an icon.

Koss' dedication to accuracy in sound reproduction is embodied in the Porta Pro's proven performance. A collapsible, portable design, complete with a convenient carrying case, allows you to enjoy this legendary sound anywhere. Further enhancing the listening experience, an adjustable headband and ComfortZone temporal pads provide unrivaled comfort and convenience.

Building upon this rich legacy, Koss has introduced the Utility Series - a new way to experience the renowned "Sound of Koss." The Porta Pro Utility features a detachable cord system, giving listeners the freedom to connect to a variety of devices.

Get started right away with the included 3.5mm Utility cord, or bundle an additional Lightning or USB-C Utility cord to connect to more of your devices. The USB-C Utility cord even includes a built-in DAC, allowing you to enjoy high-resolution 24-bit/96kHz audio.

For added convenience, the Lightning and USB-C Utility cords feature an in-line microphone and remote, enabling you to answer/end calls, control your music, and activate your device's voice assistant. This seamless integration of audio performance and versatility makes the Porta Pro Utility the most adaptable iteration yet.

Koss' unwavering commitment to innovation is further exemplified by their product timeline. From the world's first SP/3 Stereophone in 1958 to the revolutionary ESP/950 electrostatic headphones in 1990, Koss has consistently pushed the boundaries of personal audio.

The legacy continues with the acclaimed KPH30i in 2017, featuring an ultra-lightweight design and high-fidelity sound. In 2021, the Utility Series introduced three new headphones with lightning, USB-C, and 3.5mm connectivity options. Just last year, Koss continued its evolution of wireless audio with the introduction of the TWS250i True Wireless Earbuds.

Through this rich history of innovation, Koss has solidified its position as a pioneer in the world of personal audio. The Porta Pro Utility stands as the latest chapter in this remarkable story, blending legendary sound with unparalleled versatility for the modern listener.
