Koss Porta Pro Double-Sided On-Ear Communication Headset

Introducing the Legendary Sound of Koss: From the Brand that Revolutionized Personal Audio

In 1958, John C. Koss forever changed the way the world listens to music when he invented the world's first SP/3 stereophone. Koss' mission was to replicate the excitement of live musical performances, allowing listeners to experience sound like never before and bringing them closer to the music they love. This dedication to accuracy in sound reproduction has earned Koss the reputation as the "Sound of Koss" among music lovers worldwide.

The Koss Legacy: Pioneering Personal Audio Innovation

Before the world's first SP/3 stereophone in 1958, John C. Koss had already developed a portable stereo photograph player with side-wing speakers. In 1960, Koss released the SP/3X, a lighter and more comfortable predecessor to the original SP/3 with superior sound quality. The iconic Pro/4AA, introduced in 1970, set the standard for full-size professional headphones with true full-frequency performance.

In 1974, Koss pushed the boundaries of audio technology with the HV/1A, the first dynamic headphone capable of reproducing all 10 audible octaves. The acclaimed Porta Pro, released in 1984, went on to set performance and comfort standards worldwide for decades. Koss continued to innovate, introducing the JCK/300 Kordless infrared wireless headphone system in 1989 and the revolutionary ESP/950 electrostatic headphones in 1990.

The Koss Tradition Lives On

Carrying on the legacy of the Pro/4 line, the Pro4S Studio Headphone, released in 2014, was specifically designed for audio professionals. In 2017, Koss introduced the KPH30i, featuring an ultra-lightweight design with remarkable high-fidelity sound. Most recently, in 2021, the Koss Utility Series brought listeners new headphone options with Lightning, USB-C, and 3.5mm connectivity.

Koss' evolution continues in 2023 with the introduction of the TWS250i True Wireless Earbuds, the latest chapter in the brand's wireless headphone revolution.
