Fostex TH909 Headphone - Open-back Flagship Audiophile Sound

The Fostex TH909 is a premium headphone based on the popular TH900MK2 closed-back headphone. Unlike the TH900MK2, the TH909 features an open-back design for improved soundstage performance, so you can enjoy your music with enhanced immersion.

Powerful 50mm Drivers with BioDyna tech for a clean and detailed sound

Driving the TH909's sound is a powerful 50mm dynamic driver that boasts low distortion and rich sound.

The 50mm drivers in the TH909 feature Fostex's proprietary Biodyna technology for improved sound accuracy throughout the entire frequency range. The result? Deep punchy bass, natural vocals, and a sparkly smooth treble reproduction for an immersive listening experience.

Specially designed metal grills and housings for stunning aesthetics

The Fostex TH909 headphone features double-layer metal grills and specially crafted housings for an elegant feel like no other. The housings are stunning in the flesh - featuring a deep red finish created by Japan Lacquer Bordeux.

Detachable cables for seamless connections to any source

Like the TH900MK2, the TH909 headphone features a removable cable system for quick and convenient cable swaps.

The TH909 supports various cable options, including balanced connections and an optional XLR cable. All cable options use high-grade 7N high-purity cables for excellent sound clarity and low noise.

The connectors use a rhodium plating finish for enhanced resistance from abrasion and corrosion, so you can swap cables confidently.

Redesigned earpads for improved comfort during long listening sessions

The TH909 headphones feature newly redesigned earpads for improved comfort during long listening sessions. Built using a low-resilience cushion, the TH909's earpads offer a soft, plush feel that you can wear comfortably for hours.
