FOSTEX

Semi-open RP stereo headphones built around a significantly renewed RP planar magnetic driver with a full-field-driven planar diaphragm originally developed by Fostex. The 4th generation RP headphones pair the evolved driver with a new housing design that further refines the sound of the planar diaphragm.

Closed-back RP stereo headphones for studio recording monitoring, carrying the 4th generation RP planar magnetic driver in a sealed version of the T50RPmk4 housing. It suppresses environmental sound leakage during vocal and instrument recording and mixing while keeping the accurate sound reproduction characteristic of RP drivers.

Semi-open gaming headphones in the RP technology series, built on Fostex's proprietary planar magnetic driver. The driver delivers a fast response for sound localization and separation during play, with a wired connection using high-quality OFC conductor cables.

Semi-open gaming headset that adds a dedicated microphone to the T50RPmk4g, using the 4th generation RP planar diaphragm driver for fast transient response. The microphone can be connected to either the left or right side, and its cable-mounted controller handles mute and volume.

Evolution of the T60RP semi-open dynamic headphone, featuring a 4th-generation full-field-driven RP planar diaphragm driver in a solid black walnut housing optimized for listening applications. Continues over 50 years of Fostex RP technology with a new housing design, refined acoustic adjustment, and dual-entry detachable cable. Includes a 2 m unbalanced Y cable with independent left/right 2-pole 3.5 mm connectors and a 3.5 mm stereo mini plug; an optional 4.4 mm balanced cable (ET-RP4.4BL2Y) and Ultrasuede ear pads (EX-EP-RP-SUEDE) are available.

Domestically produced (Made in Japan) variant of the T60RPmk2 semi-open RP planar magnetic stereo headphone.

Flagship closed-back planar magnetic headphone in the TH Premium Series. Second-generation Premium RP driver with optimized air-damping control, paired with a hard maple housing hand-dyed in traditional Awa Aizome indigo by Tokushima artisans. Magnesium-alloy mechanical parts reduce weight by roughly 20% versus the previous design, while a new two-layer ear pad using silk-protein-based synthetic leather and natural sheepskin head pads improve long-session comfort. Detachable cable system uses 2-pole 3.5 mm connectors on the cups; ships with a 2 m 7N high-purity OFC unbalanced Y cable terminated in a 6.3 mm gold-plated stereo plug.

Open-back premium planar magnetic headphones featuring Fostex's evolved RP driver (mk2) with optimized air damping. Housing is hand-carved hard maple finished in traditional Awa Aizome (Japanese indigo) using plant-based Hon-ai dye, hand-applied and dried over several days so every pair shows unique grain and color variation. Newly designed ear pads pair sloped contact surfaces with a two-layer urethane structure (soft outer / high-elasticity inner) wrapped in silk protein synthetic leather (roughly 3x the durability of the previous generation), and natural sheepskin is used for the headband and head pad. Lightweight magnesium-alloy mechanical parts cut around 20% of the weight versus aluminum equivalents. A detachable 2-pole 3.5mm connector at each cup makes re-cabling easy; ships with a 2m 7N (99.99999%)-grade high-purity OFC cable terminated in a 6.3mm gold-plated 3-pole plug. Assembled one by one at Fostex's factory in Japan.

First in the NF series to adopt an aluminum die-cast body. The NF04R is a compact 2-way active monitor speaker featuring a newly designed 4-inch (100 mm) HR-shaped woofer and a 19 mm soft dome tweeter with UFLC diaphragm. The cabinet is an aluminum die-cast enclosure tuned with a bass reflex port, delivering tight, high-speed bass that transcends its size. A bi-amplified D-class amplifier section drives the woofer with 30 W and the tweeter with 20 W. Low-frequency, tweeter level, and input gain switches let the user tailor the monitor to its acoustic environment and to the level of connected sources.

The NF06 is a new near-field passive monitor speaker created using technology accumulated over many years of developing professional monitor speakers. It is designed for professional studios and thoroughly pursues the reference performance required in today's music production. The newly developed 6.5-inch woofer unit exclusively for the NF06 employs an HR diaphragm to disperse the peaks of specific frequencies caused by split vibration and eliminate natural sound, while ensuring high rigidity while being lightweight. Achieves high resolution and speedy low frequency playback. The front and rear positions of the woofer and tweeter were carefully listened to and time alignment adjustments were made. The bass emitted from the bass reflex port located at the bottom of the woofer's baffle can suppress unnecessary changes in low frequencies caused by the wall on the back of the speaker when installed on a studio speaker stand.
