Sony
Tokyo (Minato), Kantō, Japan · founded 1946
One of the very few audio makers whose range spans mass-market ANC earbuds to genuine summit-fi: the same brand behind the ubiquitous WH-1000XM series also builds the multi-thousand-dollar Signature Series (IER-Z1R, MDR-Z1R) and flagship Walkman DAPs, all with in-house driver and processor engineering.
Sony is the personal-audio and headphone business of Sony Group Corporation, one of the world’s largest electronics and entertainment conglomerates. Its audio line spans mass-market wireless — the flagship WH-1000XM noise-cancelling over-ears and WF-1000XM true-wireless earbuds — through to the audiophile Signature Series (IER-Z1R IEM, MDR-Z1R over-ear headphone) and high-end Walkman players. Sony is a full-stack manufacturer that designs its own drivers, processors (e.g. the QN-series ANC chips), and DACs/amps. The parent Sony Group was founded in 1946 in Tokyo as Tokyo Tsushin Kogyo K.K. by engineer Masaru Ibuka and physicist Akio Morita, adopting the Sony name in 1958. It is publicly traded (Tokyo Stock Exchange: 6758; NYSE: SONY), so the personal-audio unit is a division of a large public conglomerate rather than an independent boutique.
