The Sound of Koss: A Legacy of Innovation in Personal Audio

In 1958, John C. Koss revolutionized the way we experience music when he invented the world's first SP/3 stereophone. Koss sought to replicate the excitement of a live musical performance, allowing listeners to immerse themselves in sound like never before. This dedication to audio accuracy has become the hallmark of the Koss brand, earning the recognition of music lovers worldwide.

The Evolution of Koss Stereophones Before the groundbreaking SP/3 in 1958, Koss had already developed a portable stereo photograph player with side-wing speakers. This paved the way for the world's first SP/3 Stereophone, which introduced personal stereo audio to the world.

In 1960, Koss released the SP/3X, a predecessor to the SP/3 with a lighter design, more comfortable headband, and superior sound quality. The Pro/4AA, introduced in 1970, set the standard for full-size professional headphones, delivering true full-frequency performance.

Koss continued to push the boundaries of audio technology. In 1974, the HV/1A became 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. The JCK/300 Kordless System, introduced in 1989, set the standard for infrared wireless headphones.

Breakthrough Innovations Koss's revolutionary ESP/950 electrostatic headphones, introduced in 1990, delivered breakthrough high-fidelity sound. The Pro4S Studio Headphone, released in 2014, carried on the legacy of the Pro/4 line, designed specifically for audio professionals.

In 2017, Koss released the acclaimed KPH30i, featuring an ultra-lightweight design with remarkable high-fidelity sound. The Utility Series, introduced in 2021, offered listeners the flexibility to connect via Lightning, USB-C, and 3.5mm. Most recently, in 2023, Koss continued its evolution of wireless headphones with the TWS250i True Wireless Earbuds.

The KPH30i: Lightweight Listening, Exceptional Sound The KPH30i packs big sound into a small, ultra-lightweight on-ear headphone. Its dynamic 60-ohm drivers deliver remarkable high-fidelity audio with deep bass, crisp highs, and a superior midrange. The rugged, yet comfortable design features an adjustable headband with a soft silicone strap for hours of listening enjoyment.

Convenient controls are built into the cable, allowing you to pause, play, skip tracks, and answer or end calls with ease. Available in four stylish colorways – White, Grey, Rhythm Beige, and Clear – the KPH30i offers a remarkable listening experience in a versatile, portable package.

Koss: A Legacy of Audio Excellence From the invention of the world's first stereophone to the latest in wireless technology, Koss has consistently pushed the boundaries of personal audio. With a commitment to quality, innovation, and the pursuit of the perfect listening experience, the Koss brand continues to be synonymous with the "Sound of Koss" – a legacy that has captivated music enthusiasts for generations.
