Koss KPH30iRB On-Ear Headphones, Retro Style, D-Profile Design, Wired with 3.5mm Plug, Rhythm Beige

The Original American Stereophone Company brand has a rich history dating back to 1958, when John C. Koss revolutionized the way the world listens to music. Koss' invention of the world's first SP/3 stereophone allowed music lovers to experience the excitement of live performances like never before, bringing them closer to the music they adore. This dedication to accurate sound reproduction has become known as "The Sound of Koss" across the Porta Pro Collection.

Koss' pioneering journey began even before the iconic SP/3 stereophone. In the late 1950s, he developed a portable stereo photograph player with side-wing speakers, paving the way for the groundbreaking SP/3 in 1958. This introduction of personal stereo audio to the world marked a pivotal moment in audio history.

Building on this success, Koss released the SP/3X in 1960, featuring a lighter design, more comfortable headband, and superior sound quality. In 1970, the Pro/4AA set a new standard for full-size professional headphones, delivering true full-frequency performance.

On June 25, 1971, John C. Koss proudly unveiled the new Koss World Headquarters in Milwaukee, Wisconsin, solidifying the company's commitment to innovation. This was followed by the release of the HV/1A in 1974, the first dynamic headphone capable of reproducing all 10 audible octaves.

The acclaimed Porta Pro, released in 1984, set performance and comfort standards worldwide for decades. In 1989, the JCK/300 Kordless Headphone system set the standard for infrared wireless headphones, while the revolutionary ESP/950 electrostatic headphones introduced breakthrough high-fidelity sound in 1990.

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 unveiled the acclaimed KPH30i, featuring an ultra-lightweight design with remarkable high-fidelity sound.

Most recently, in 2021, Koss introduced the Utility Series, offering listeners the flexibility to connect via Lightning, USB-C, and 3.5mm. And in 2023, Koss continued its evolution of wireless headphones with the TWS250i True Wireless Earbuds.

The KPH30i exemplifies Koss' commitment to innovation and exceptional audio quality. Packing big sound into a small, ultra-lightweight on-ear design, the KPH30i delivers remarkable high-fidelity audio with deep bass, crisp highs, and a superior midrange. Its rugged yet comfortable construction, adjustable headband with a soft silicone strap, and in-line microphone and remote make it the perfect choice for any listening situation.

Available in four stylish colorways – White, Grey, Rhythm Beige, and Clear – the KPH30i offers a remarkable listening experience for music enthusiasts of all tastes. With its durable, ultra-lightweight design and high-fidelity audio performance, the KPH30i continues the Koss legacy of excellence and innovation.
