Fostex TH900 MK2 Headphones - Over/On Ear Selling my TH900 MK2. The ear cups are in good condition and the headband has some minor marks. Includes the 1/4” cable, the stand, the original pads, a pair of dekoni full leather pads and the box. (includes the Fostex stand not the wooden one pictured) Condition: Good Payment Method: EFT, Cash on Pickup Region/State: (WA) Western Australia/Australia By Swifty 0 Comments AUD $850 Date: May 2, 20241 yr
A$850 is above the median but still comfortably within the local market for this model, so it reads as fair-to-strong rather than cheap. Against your benchmark set, it sits well above the A$484 median and below the A$891 75th percentile, which makes it a solid listing if the condition and package are genuinely clean.
These are widely respected closed-back flagships with a big, vivid, highly resolving presentation, deep bass, and the kind of build and finish that still feel special. In good condition, they’re a proper long-term buy; if it includes the original pads, cable, and box, that helps the value further. I’d mostly be checking for pad wear, headband condition, and any driver imbalance, since those are the meaningful ownership items on a headphone like this.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Fostex emerged in 1973 as the branded consumer and professional division of Foster Electric Co., Ltd., a Japanese loudspeaker manufacturer founded in 1949. Established to bring Foster's high-quality speaker components directly to dealers and customers, Fostex quickly gained international recognition through innovative products like the T20RP headphones and 6301 studio monitors. The brand's foundation rests on Foster's position as one of the world's largest OEM loudspeaker developers, employing tens of thousands across multiple countries and manufacturing millions of speaker units monthly.
The company built its reputation across three interconnected product categories: professional studio equipment, consumer headphones, and powered monitor speakers. Fostex became particularly renowned for pioneering RP (Regular Phase) technology, which delivers clear sound with high sensitivity and wide dynamic range—a signature that defines their headphones, microphones, and speaker designs. Beginning in 1978, the brand expanded into professional speaker development, eventually introducing the PM series of powered monitors and establishing itself as a trusted choice for recording studios, broadcast facilities, and serious home listeners.
Fostex occupies a distinctive middle ground in the audio market: neither ultra-premium boutique nor mass-market consumer, but rather a respected specialist brand with deep professional credentials. Their products appeal to recording engineers, studio owners, and discerning hi-fi enthusiasts who prioritize accuracy and reliability over luxury positioning. The 6301B monitor remains an industry standard after decades in production, while the T20RP headphones maintain popularity among studio professionals—testament to Fostex's enduring reputation for sonic integrity and engineering excellence.
