Koss The Plug In-Ear Headphones (Black)

From the brand The Original American Stereophone Company

In 1958, John C. Koss revolutionized the way we listen to music by inventing the world's first SP/3 stereophone. Koss sought to replicate the excitement of a live musical performance, allowing listeners to experience sound like never before and bringing them closer to the music they love. Music lovers around the world recognize Koss's dedication to accuracy in sound reproduction as the "Sound of Koss Porta Pro Collection."

The journey of Koss's innovations in audio technology began with the development of a portable stereo photograph player with side-wing speakers, even before the world's first SP/3 Stereophone in 1958. This groundbreaking invention introduced personal stereo audio to the world.

In 1960, Koss released the predecessor to the SP/3, the SP/3X, featuring a lighter design, a 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.

On June 25, 1971, John C. Koss proudly unveiled the new Koss World Headquarters in Milwaukee, Wisconsin. In 1974, Koss released the HV/1A, 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 to come.

In 1989, the JCK/300 Kordless Headphone system set the standard for infrared wireless headphones. Koss's revolutionary ESP/950 electrostatic headphones, introduced in 1990, brought breakthrough high-fidelity sound. The Pro4S Studio Headphone, launched 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. In 2021, the Koss Utility Series introduced three new headphones, allowing listeners to connect via Lightning, USB-C, and 3.5mm. Koss's evolution of wireless headphones continued in 2023 with the TWS250i True Wireless Earbuds.

The Plug, Koss's latest in-ear headphone offering, delivers exceptional noise isolation and high-fidelity audio in a wide array of colors. Dynamic elements and acoustical vents combine to produce a superior audio experience with a frequency range of 10-20,000 Hz, delivering deep bass and crisp highs. The Plug's memory foam cushions mold to the inside shape of the ear, blocking out unwanted ambient noise for an immersive listening experience. With a sleek, sophisticated design and a 3.5mm standard headphone jack, The Plug offers a magical listening experience in a compact and versatile package.
