John C. Koss, the founder of The Original American Stereophone Company, revolutionized the way we listen to music forever when he created the world's first SP/3 stereophone in 1958. The aim was to recreate the thrill of a live musical performance, allowing listeners to experience sound in an entirely new way and bringing them closer to the music they love. This dedication to accuracy in sound reproduction is now known as The Sound of Koss Porta Pro Collection.
The evolution of Koss headphones began with the development of a portable stereo phonograph player with side-wing speakers before the creation of the world's first SP/3 Stereophone in 1958. This marked the introduction of personal stereo audio to the world. Subsequent advancements such as the release of the SP/3X in 1960, the Pro/4AA in 1970, and the Porta Pro in 1984 set new standards for sound quality, comfort, and versatility in audio technology.
Over the years, Koss continued its legacy of innovation with the release of the JCK/300 Kordless Headphone system in 1989, the ESP/950 electrostatic headphones in 1990, and the Pro4S Studio Headphone in 2014, catering to the evolving needs of audio professionals.
In 2021, Koss introduced the Utility Series, featuring new headphones that allow listeners to connect via Lightning, USB-C, and 3.5mm, while in 2023, the TWS250i True Wireless Earbuds showcased the brand's ongoing commitment to advancing wireless headphone technology.
One of Koss's most popular and affordable audio solutions is the KPH7. This lightweight headphone comes in a variety of colors, making it a preferred choice for individuals looking to express their unique style. It is also an ideal option for institutions seeking a budget-friendly audio solution, such as schools, libraries, and learning labs. The KPH7's ultra-lightweight design, adjustable headband, and foam cushions ensure a comfortable listening experience for extended sessions.
With a frequency response of 80 - 18,000 Hz, impedance of 32 Ohms, and 4ft cord with a standard 3.5mm connector, the KPH7 delivers an impressive audio experience at an unbeatable value.
