about fostex
Fostex was established in 1973 as the branded-products arm of Foster Electric, the Japanese transducer manufacturer incorporated in 1948 that has long been one of the world's largest OEM suppliers of loudspeakers and drivers. That OEM heritage underpins everything Fostex builds: the company applies driver and transducer engineering developed at scale for other brands to products sold under its own name. The consumer high point of the line is the TH-series headphone family. The TH900 is the flagship closed-back, built around a biodynamic diaphragm and a lacquered wooden housing, with the TH909 as an open-back variant. Around the headphones, Fostex carries headphone amplifiers and DACs in its HP series, portable listening devices, and a deep catalog of full-range drivers and pro-audio components that connect back to the Foster Electric core business. Fostex sits more in the headphone-enthusiast and pro-audio tier than in the high-end speaker tier, competing with the other Japanese headphone and personal-audio makers. US distribution for the consumer line runs through American Music & Sound as Fostex USA, and the products are carried by Sweetwater, Vintage King, and Audio46. The TH900 and TH909 have been reviewed extensively by Headfonia, Head-Fi, and Headphones.com. The brand is headquartered in Akishima, Japan, under the Foster Electric group.
