Designs, manufactures, and sells stereo headphones and related accessories in one audio/video business. Its lineage includes the SP/3 stereophone, PRO/4, ESP/6 electrostatic model, and collapsible Porta Pro; the company describes the SP/3 as its first high-fidelity stereophone. Introduced in 1958, the SP/3 established the product direction that continues today. The PRO/4 series became a recording-industry standard.
International sales account for a material portion of revenue. A lifetime warranty introduced in 1989 covers its stereo-headphone line, while the company relies almost exclusively on contract-manufacturing facilities in the People’s Republic of China.
