Fostex Corp. TH1100RP Premium Planar Headphones for Audiophiles

Flagship Planar Headphones for Audiophiles

The Fostex TH1100RP is a premium open-back headphone designed for audiophiles seeking exceptional sound quality and craftsmanship. Featuring Fostex's proprietary RP planar magnetic driver technology, these headphones deliver a natural sound field with high resolution and minimal listening fatigue. The solid hard maple wood housing, hand-dyed using the traditional Aizome indigo technique from Tokushima, Japan, not only provides a unique aesthetic but also contributes to the acoustic performance by minimizing resonance.​

Advanced RP Planar Magnetic Driver

At the heart of the TH1100RP lies a newly developed RP planar magnetic driver, larger than previous models, offering improved sensitivity and a smooth frequency response. The redesigned magnetic circuit optimizes magnetic flux distribution, enhancing transient characteristics and enabling precise sound reproduction across a wide frequency range. This technology ensures accurate and delicate reproduction from deep bass to high frequencies, providing a clear sound image with a strong sense of localization.​

Exquisite Craftsmanship and Materials

The TH1100RP's housing is crafted from hard maple wood, known for its acoustic properties, and is meticulously hand-dyed with Awa Aizome, a traditional Japanese indigo dye. This process results in a deep indigo color that beautifully reveals the unique grain of each piece of wood, making every headphone set unique. The use of magnesium alloy components reduces the overall weight by 20% compared to aluminum, enhancing comfort during extended listening sessions.​Audio46 Headphone Store+5Addicted To Audio+5fostex.jp+5
