The result is a wide, spacious soundstage with precise instrument localization and depth of field. The double-layer etched metal grille diversifies the resonance points of the housing, preventing energy concentration at specific frequencies — while also providing the housing's characteristic visual depth. The BioDyna diaphragm in bio-cellulose and composite fibers delivers low specific gravity, high Young's modulus, high internal loss, and a free-edge design. Frequency response: 5–45,000 Hz, impedance: 25 Ω, sensitivity: 100 dB\/mW, maximum input: 1,800 mW.

The bio-cellulose and composite fiber diaphragm delivers low specific gravity, high Young's modulus, high internal loss, and a free-edge design for linear large-amplitude reproduction in the low midrange. The closed chamber builds acoustic pressure on the internal side of the earcup; combined with the precise acoustic path tuning of the TH900mk2, this yields the model's characteristic sound profile — intense, fast bass, an engaged midrange, and an extended high-frequency range without smearing — alongside passive environmental isolation.

The closed acoustic chamber changes the operating conditions of the diaphragm relative to the open-back model: acoustic pressure builds on the internal side of the earcup, which — combined with the correct geometry and internally applied absorbing material — translates into a higher output level (100 dB\/mW sensitivity), a stronger bass emphasis, and effective passive isolation from environmental noise without active noise cancellation.

Dense Japanese maple introduces no tonal coloration of its own — delivering firm, deep bass and clear, resonant treble.

The RP (Regular Phase) driver is a technology Fostex has been refining since 1974; in the TH1100RPmk2 it uses the largest fully driven planar diaphragm Fostex has ever produced in a headphone. The solid Japanese maple housing is dyed using Awa Aizome — traditional Japanese indigo dyeing with plant-based Hon-ai dye from Tokushima Prefecture, applied by hand over several days with curing intervals between coats. The open acoustic chamber of the TH1100RPmk2 features double-layered precision-machined aluminium apertures with a carefully calibrated opening ratio.\u003c\/p\u003e\n\n  \u003ch3\u003eRP mk2 driver with air damping control for optimized diaphragm amplitude\u003c\/h3\u003e\n  \u003cp\u003eThe defining change between the TH1100RP and the mk2 is inside the transducer: air damping control has been optimized through revised airflow geometry using new damping materials, complemented by new earpads that alter the acoustic conditions directly in front of the diaphragm. The result is better control of diaphragm amplitude in the low-frequency range without compromising transient speed or resolution in the midrange and treble. The fully driven RP planar driver differs from conventional planar designs in that the magnetic field covers the entire diaphragm surface in uniform phase — eliminating localized diaphragm deformation and reducing non-stationary resonances. The TH1100RPmk2's magnetic circuit uses an increased number of magnets sandwiching the diaphragm, a newly designed printed coil pattern and shape, and redesigned magnetic flux distribution components. Frequency response: 5–40,000 Hz, impedance: 32 Ω.\u003c\/p\u003e\n\n  \u003ch3\u003eAwa Aizome housing, double aluminium apertures and magnesium alloy 20% lighter than aluminium\u003c\/h3\u003e\n  \u003cp\u003eThe solid Japanese maple housing is dyed with Hon-ai — plant-based natural indigo historically used in Japan, including by Hokusai in the Thirty-six Views of Mount Fuji woodblock print series. The dyeing process takes several days with curing intervals; temperature and humidity affect the penetration of dye pigment into the wood grain, making every unit unique in depth and distribution of color. Dense Japanese maple does not introduce its own tonal coloration due to its material properties — delivering firm, deep bass and clear, resonant treble. The open chamber features double-layered precision-machined aluminium apertures with a calibrated opening ratio optimized for soundstage reproduction and minimal listening fatigue. Mechanical components including the housing base plate and yoke are machined from magnesium alloy, reducing overall weight by 20% compared to the aluminium used in the previous generation.

Solid black walnut has higher density and internal damping than the acacia used in the TH810\/818, giving the TH616 a darker, more focused housing resonance that acoustically aligns it closer to the TH808. The baffle plate is made from high-specific-gravity resin, a material selected specifically to minimize resonance noise — translating according to Fostex into higher resolution, a richer midrange, and better-controlled bass reproduction. All mechanical components including the yoke and headband adjustment are machined from aluminium for rigidity without added weight.

The bio-cellulose and composite fiber diaphragm is constructionally identical to higher models — low specific gravity, high Young's modulus, high internal loss, and a free-edge design for linear large-amplitude reproduction in the low midrange.

The TH808 sits above the TH818 in Fostex's lineup with a wider stated frequency range (5–45,000 Hz) and a housing material with a distinct acoustic character.

The 5–45,000 Hz frequency range extends deeper at the low end (5 Hz versus 12.5 Hz in the TH810\/818) and higher into the ultrasonic region (45 kHz versus 40 kHz), reflecting differences in housing tuning and acoustic loading. At 25 Ω impedance and 100 dB\/mW sensitivity, the TH808 drives from a portable amplifier or headphone output of an audio interface or instrument without issue; the 1,800 mW maximum input rating ensures compatibility with high-output desktop headphone amplifiers. The matte black walnut housing shows individual grain and texture variation per unit; machined aluminium components complement the wood, reducing resonance and keeping weight in check.\u003c\/p\u003e\n\n  \u003ch3\u003eLow-resilience earpads and dual-sided cable routing\u003c\/h3\u003e\n  \u003cp\u003eThe TH808's earpads use low-resilience urethane foam covered in high-grade synthetic leather — identical in construction to the TH909's pads, conforming to the shape of the outer ear and improving passive isolation at the rear of the cup.

The closed acoustic chamber builds pressure in a way that typically favors the characteristic resonance issues of closed headphones; Fostex minimizes this deliberately through housing material selection and geometry. Acacia wood replaces the Japanese-lacquered maple of the flagship models — acacia is used in stringed instruments including guitars and ukuleles for its resonant properties, which carry over into the acoustic character of the housing. Every TH810 unit shows individual variation in wood grain, texture, and color, with no effect on acoustic performance. Electrical parameters are identical to the TH818: 25 Ω impedance, 100 dB\/mW sensitivity, 1,800 mW maximum input, 12.5 Hz to 40,000 Hz frequency response.

The mk3 debuted in 2015 as the successor to the mk2, introducing a redesigned diaphragm with improved damping, new low-rebound ear pads, and an updated headband.

A dedicated headphone amplifier is a practical requirement for professional monitoring work — the mk3 will not reach adequate SPL from a laptop headphone output or low-voltage audio interface. The mk3's flat frequency response neither flatters nor deceives: bass is accurate without colouration, the midrange is neutral, and the improved diaphragm damping relative to the mk2 reduced the characteristic dip around 4 kHz. Cable entry is left-cup only, via a proprietary locking 3.5 mm TRS socket — a fundamental wiring difference from the mk4, which has symmetrical sockets on both sides.\n\n\u003ch3\u003eT50RPmk3 as a modification platform\u003c\/h3\u003e\nNo headphone series has been modified as extensively as the T50RPmk3.

The stock sound is neutral and monitoring-accurate, but requires amplification. Ear pad modifications (ZMF Ori, Dekoni Blue, and others) shift the bass profile and soundstage in predictable, well-documented ways. OEM replacement pads EX-EP-RPmk3 restore the factory acoustic profile when the originals wear out.

The generational difference is substantially deeper than the mk2-to-mk3 transition, which was primarily a tuning revision on the same driver geometry. The mk4 introduces a redesigned printed coil trace pattern that expands and equalizes the diaphragm vibration area, increased magnet count sandwiching the diaphragm for stronger controlled drive, optimized magnetic flux distribution eliminating self-resonance modes, and a completely new housing geometry. The electrical result is measurable: impedance dropped from 50 Ω (mk3) to 28 Ω, and sensitivity rose from 91 dB\/mW to 97 dB\/mW — the mk4 drives adequately from an audio interface or portable source without a dedicated headphone amplifier, whereas the mk3 required substantial output voltage in the same context.

The mk4 introduces a 4-pole 3.5 mm TRRS socket on both earcups — the cable connects on either side with no tonal difference. Symmetrical housing eliminates the acoustic L\/R asymmetry caused by differing internal structures between sides. The 4-pole socket is balanced-capable from the factory — optional balanced cables ET-RP2.5BL (2.5 mm), ET-RP4.4BL (4.4 mm), and ET-RPXLR connect without adapters. The T50RPmk4 retains its status as a modding platform: ear pad swaps, internal damping modifications, and acoustic tuning remain viable, with a significantly higher stock performance baseline than the mk3.\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4th-generation RP driver — new coil trace pattern, increased magnets, optimized magnetic circuit\u003c\/li\u003e\n\u003cli\u003e28 Ω impedance \/ 97 dB\/mW sensitivity — drives from audio interfaces and portable sources without a dedicated amplifier\u003c\/li\u003e\n\u003cli\u003eFrequency response 10 Hz – 40,000 Hz — extended vs mk3 (15 Hz – 35,000 Hz)\u003c\/li\u003e\n\u003cli\u003eSymmetrical housing with bilateral 4-pole TRRS 3.5 mm sockets — no L\/R acoustic asymmetry\u003c\/li\u003e\n\u003cli\u003eBalanced-capable out of the box — compatible with ET-RP2.5BL, ET-RP4.4BL, ET-RPXLR balanced cables\u003c\/li\u003e\n\u003cli\u003eSemi-open design — acoustically unified with T50RPmk4CL closed-back platform\u003c\/li\u003e\n\u003cli\u003eLow-rebound circumaural ear pads — optional Ultrasuede EX-EP-RP60 available separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: T50RPmk4\u003c\/li\u003e\n\u003cli\u003eDriver type: Planar magnetic RP (Regular Phase), 4th generation\u003c\/li\u003e\n\u003cli\u003eDesign: Semi-open\u003c\/li\u003e\n\u003cli\u003eImpedance: 28 Ω\u003c\/li\u003e\n\u003cli\u003eSensitivity: 97 dB\/mW\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz – 40,000 Hz\u003c\/li\u003e\n\u003cli\u003eMaximum input power: 3,000 mW\u003c\/li\u003e\n\u003cli\u003eEarcup connectors: 4-pole 3.5 mm TRRS (symmetrical bilateral)\u003c\/li\u003e\n\u003cli\u003eWeight: approx. 330 g (without cable)\u003c\/li\u003e\n\u003cli\u003eIncluded accessories: OFC cable 3.5 mm (4-pole to 3-pole, 2 m), 3.5 mm to 6.3 mm adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"FOSTEX","offers":[{"title":"Default Title","offer_id":53693023650129,"sku":"59491","price":200.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/FostexT50RPmk41.jpg?v=1777977067"},{"product_id":"fostex-t50rpmk4g","title":"Fostex T50RPmk4g","description":"\u003cdiv lang=\"en\"\u003e\n\u003cstrong\u003eFostex T50RPmk4g\u003c\/strong\u003e is a semi-open gaming headphone built on the identical hardware platform as the T50RPmk4 — fourth-generation RP planar driver in a symmetrical housing with sockets on both sides.

The fourth generation introduces a redesigned printed coil pattern — new trace geometry expands and equalizes the vibrating area across the full diaphragm surface. The number of magnets sandwiching the diaphragm has been increased, and the magnetic circuit components were rebuilt to optimize flux distribution, suppressing diaphragm self-resonance modes. The practical results are faster attack and decay, higher sensitivity at the same 28 Ω impedance, and more consistent frequency response — most audible in percussion transients and stereo localization accuracy. At 28 Ω, the T60RPmk2 is driveable from portable DAC\/amp combinations and audio interfaces without a dedicated headphone amplifier.\n\n\u003ch3\u003eBlack walnut housing and the new cable system\u003c\/h3\u003e\nThe semi-open geometry of the T60RPmk2 is a deliberate compromise: wider soundstage and more natural spatial imaging than a closed design, with more defined bass separation than a fully open construction. Solid black walnut provides natural damping of the housing's own resonance modes while contributing a warm midrange character — a complement to the inherently neutral and fast-transient planar drive technology. The new Y-cable system with two independent 3.5 mm TS sockets per earcup replaces the proprietary single connector of the original T60RP, improving third-party cable compatibility. The optional balanced cable ET-RP4.4BL2Y (4.4 mm Pentaconn) is available separately. Optional Ultrasuede EX-EP-RP-SUEDE ear pads are available as an upgrade over the stock low-rebound pads.\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4th-generation RP planar driver — redesigned printed coil, increased magnets, faster transient vs. 3rd gen\u003c\/li\u003e\n\u003cli\u003eSemi-open solid black walnut housing — natural soundstage, warm midrange character\u003c\/li\u003e\n\u003cli\u003e28 Ω impedance — driveable from portable DAC\/amp units and audio interfaces\u003c\/li\u003e\n\u003cli\u003eDual 3.5 mm TS earcup sockets (Y-cable) — independent channel connections, tool-free cable swaps\u003c\/li\u003e\n\u003cli\u003eCompatible with ET-RP4.4BL2Y balanced cable (4.4 mm Pentaconn)\u003c\/li\u003e\n\u003cli\u003eLow-rebound ear pads as standard — optional Ultrasuede EX-EP-RP-SUEDE available separately\u003c\/li\u003e\n\u003cli\u003eManufactured at Fostex domestic factory — integrated production for consistent quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: T60RPmk2\u003c\/li\u003e\n\u003cli\u003eDriver type: Planar magnetic RP (Regular Phase), 4th generation\u003c\/li\u003e\n\u003cli\u003eDesign: Semi-open\u003c\/li\u003e\n\u003cli\u003eImpedance: 28 Ω\u003c\/li\u003e\n\u003cli\u003eSensitivity: 96 dB\/mW\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz – 40,000 Hz\u003c\/li\u003e\n\u003cli\u003eMaximum input power: 3,000 mW\u003c\/li\u003e\n\u003cli\u003eHousing material: Solid black walnut\u003c\/li\u003e\n\u003cli\u003eEarcup connectors: 2x 3.5 mm TS (2-pole), Y-cable\u003c\/li\u003e\n\u003cli\u003eWeight: approx. 360 g (without cable)\u003c\/li\u003e\n\u003cli\u003eIncluded accessories: OFC Y-cable with 3.5 mm connector, 3.5 mm to 6.3 mm adapter, pouch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"FOSTEX","offers":[{"title":"Default Title","offer_id":53693027582289,"sku":"59479","price":611.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/FostexT60RPmk21.jpg?v=1777976964"},{"product_id":"fostex-t60rpmk2cl","title":"Fostex T60RPmk2CL","description":"\u003cdiv lang=\"en\"\u003e\n\u003cstrong\u003eFostex T60RPmk2CL\u003c\/strong\u003e is the closed-back variant of the T60RPmk2 — the same fourth-generation RP planar driver in a solid black walnut housing, acoustically re-tuned for sealed enclosure performance. It fills the gap in the RP lineup between the semi-open T60RPmk2 and the monitoring-focused T50RPmk4, delivering full ambient isolation and the denser, more contained sound characteristic of a closed chamber. The dual 2-pole 3.5 mm TS earcup sockets and Y-cable topology are identical to the T60RPmk2, making the optional balanced cable ET-RP4.4BL2Y a direct fit.\n\n\u003ch3\u003eClosed chamber and fourth-generation RP driver — the acoustic interaction\u003c\/h3\u003e\nA planar magnetic driver inside a sealed enclosure operates under different air-load conditions than in a semi-open housing. Fostex carried out separate acoustic tuning on the T60RPmk2CL — rear chamber volume, internal damping, and vent ratio — to let the fourth-generation driver, with its redesigned printed coil, increased magnet count, and optimized flux distribution, reach its performance targets within that specific geometry. The practical result is extended bass relative to the T60RPmk2, since the sealed chamber increases effective air-spring loading at low frequencies, while the inherent speed of the planar driver keeps transient performance and resolution intact. Full ambient isolation makes the T60RPmk2CL useful where the T60RPmk2 falls short — loud recording environments, tracking sessions where headphone bleed into microphones is a concern, and listening situations requiring maximum acoustic separation from the room.\n\n\u003ch3\u003eBlack walnut housing and cable system\u003c\/h3\u003e\nSolid black walnut has natural damping properties that distinguish it acoustically from harder woods like hard maple used in the T60RPmk2ai. Where maple's stiffness yields a tighter, more transparent presentation, walnut's density and grain structure absorb certain resonance modes while contributing a warmer character in the midrange — a quality that complements the closed-back format's inherently fuller low end. Natural wood grain means every unit looks different; grain, colour, and texture variations are normal and have no effect on acoustic performance. The dual 3.5 mm TS earcup sockets allow tool-free cable swaps. The included cable is OFC terminated in 3.5 mm with a 6.3 mm adapter; the optional ET-RP4.4BL2Y balanced Y-cable is available separately.\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4th-generation RP planar driver — redesigned printed coil, increased magnets, sharp attack and decay\u003c\/li\u003e\n\u003cli\u003eClosed-back solid black walnut housing — acoustically tuned for sealed enclosure performance\u003c\/li\u003e\n\u003cli\u003eFull ambient isolation — effective for tracking, recording environments, and room-isolated listening\u003c\/li\u003e\n\u003cli\u003eDual 2-pole 3.5 mm TS earcup sockets — Y-cable topology, tool-free cable replacement\u003c\/li\u003e\n\u003cli\u003eCompatible with ET-RP4.4BL2Y balanced cable (4.4 mm Pentaconn)\u003c\/li\u003e\n\u003cli\u003eAngled low-rebound ear pads — comfort over long sessions; optional Ultrasuede EX-EP-RP-SUEDE available\u003c\/li\u003e\n\u003cli\u003eManufactured at Fostex domestic factory — integrated production for consistent quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: T60RPmk2CL\u003c\/li\u003e\n\u003cli\u003eDriver type: Planar magnetic RP (Regular Phase), 4th generation\u003c\/li\u003e\n\u003cli\u003eDesign: Closed-back\u003c\/li\u003e\n\u003cli\u003eImpedance: 28 Ω\u003c\/li\u003e\n\u003cli\u003eSensitivity: 98 dB\/mW\u003c\/li\u003e\n\u003cli\u003eFrequency response: 10 Hz – 40,000 Hz\u003c\/li\u003e\n\u003cli\u003eMaximum input power: 3,000 mW\u003c\/li\u003e\n\u003cli\u003eHousing material: Solid black walnut\u003c\/li\u003e\n\u003cli\u003eEarcup connectors: 2x 3.5 mm TS (2-pole)\u003c\/li\u003e\n\u003cli\u003eIncluded accessories: OFC Y-cable with 3.5 mm connector, 3.5 mm to 6.3 mm adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"FOSTEX","offers":[{"title":"Default Title","offer_id":53693027877201,"sku":"59486","price":627.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/FostexT60RPmk2CL1.jpg?v=1777976926"},{"product_id":"fostex-t60rpmk2ai","title":"Fostex T60RPmk2ai","description":"\u003cdiv lang=\"en\"\u003e\n\u003cstrong\u003eFostex T60RPmk2ai\u003c\/strong\u003e is a semi-open planar magnetic headphone built around the fourth-generation RP driver, housed in a solid hard maple enclosure hand-dyed with Awa indigo by craftsmen in Tokushima Prefecture. It is the first Made in Japan model in the T60RP line — every unit is assembled by hand at Fostex's domestic factory. Standard equipment includes Toray Ultrasuede® ear pads and 7N-grade OFC internal wiring (99.99999% purity), the same internal wiring specification used in the flagship TH1000RPmk2 and TH1100RPmk2.\n\n\u003ch3\u003eHard maple housing and Awa-Ai dyeing — acoustic significance\u003c\/h3\u003e\nThe switch from black walnut (T60RPmk2) to hard maple is an acoustic decision as much as an aesthetic one. Hard maple is denser and stiffer than walnut, which reduces the housing's own resonance modes and yields a tighter soundstage, better transparency, and faster attack — most audible in percussion transients and string harmonics. The Awa-Ai dyeing process uses only natural indigo plant pigment with no synthetic fixatives; the pigment penetrates the wood structure rather than forming an external lacquer layer. This preserves the housing's acoustic behaviour more faithfully than hard-film finishes. Because each piece of maple has a unique grain, the pigment penetration depth and final colour vary between units — no two T60RPmk2ai housings are acoustically or visually identical.\n\n\u003ch3\u003eFourth-generation RP driver and 7N OFC wiring — differences vs T60RPmk2\u003c\/h3\u003e\nBoth the T60RPmk2ai and T60RPmk2 use the same fourth-generation planar driver: redesigned printed coil pattern, increased magnet count, and optimized magnetic flux distribution for improved sensitivity, smoother frequency response, and faster transient performance relative to the third generation. The key differentiator is internal wiring: the T60RPmk2ai uses 7N-grade OFC throughout the internal signal path instead of standard OFC, keeping conductor purity consistent from driver to earcup socket.

More critically, the low-rebound foam beneath is matched to the TH900mk2 cup profile: it maintains consistent contact pressure around the full perimeter of the ear, preserving the acoustic seal of the closed chamber.

The pads use high-grade synthetic leather over low-rebound foam, matching the factory specification exactly. At this price and performance tier, fitting non-OEM pads carries a real acoustic risk; EX-EP-99 removes that variable entirely.\n\n\u003ch3\u003eAcoustic integrity in an open-back design\u003c\/h3\u003e\nOpen-back headphones are often assumed to be acoustically indifferent to pad geometry — they are not. The pad profile on the TH909 and TH808 directly affects bass coupling and stereo image coherence at the ear. Low-rebound foam of the correct density maintains even contact between the cup and the head without excessive lateral pressure, which is critical for preserving the tonal balance these drivers were voiced for. Aftermarket pads with different foam density or contact geometry shift this balance in ways that are audible and difficult to quantify without measurement. EX-EP-99 retains the factory mechanical parameters, keeping the driver's frequency response consistent with its published specification.\n\n\u003ch3\u003eLong-session comfort on reference-grade headphones\u003c\/h3\u003e\nThe TH909 and TH808 are built for extended critical listening and mastering work. The ear pads need to sustain hours of skin contact without generating pressure points or retaining heat. The high-grade leatherette used in EX-EP-99 is more resistant to abrasion and sweat-induced degradation than generic aftermarket materials.

They address a practical problem: stock leatherette pads on planar magnetic cans become uncomfortable during extended monitoring work, trap heat, and can subtly alter the acoustic seal depending on sweat and skin oil buildup over time. These pads replace both the comfort and the acoustic interface in one upgrade.\n\n\u003ch3\u003eExtended session comfort without compromising isolation\u003c\/h3\u003e\nThe low-rebound foam core is tuned in both thickness and density to distribute lateral clamping force evenly across the pinna. No single pressure point dominates, which is the main cause of fatigue-induced headaches after four-plus hours at a console. Ultrasuede® manages moisture and airflow better than solid synthetic leather — it breathes without the acoustic leakage of open-weave fabric, keeping the seal consistent throughout the session. Each pad weighs 15.5 g, so the overall headphone balance remains unchanged after swapping.\n\n\u003ch3\u003eAcoustic effect of the material change\u003c\/h3\u003e\nSwitching pad material is not cosmetic — it directly affects the headphone's frequency response at the ear. The textile surface of Ultrasuede® modifies acoustic impedance at the ear canal compared to leatherette, typically producing a slightly smoother midrange and more consistent bass response regardless of head positioning. For mixing and critical listening work, this translates to less variation between different fitting positions, meaning your reference point stays stable across a session.\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUltrasuede® fabric by Toray Industries — soft, durable, breathable\u003c\/li\u003e\n\u003cli\u003eLow-rebound foam core with optimized thickness for even lateral pressure distribution\u003c\/li\u003e\n\u003cli\u003eModerate breathability and moisture permeability — prevents heat and sweat buildup\u003c\/li\u003e\n\u003cli\u003eSmooth frequency response from bass to treble — reduced listening fatigue\u003c\/li\u003e\n\u003cli\u003eTool-free installation — stretch-and-clip mounting onto the cup rim\u003c\/li\u003e\n\u003cli\u003eSold as a matched pair\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: EX-EP-RP-SUEDE\u003c\/li\u003e\n\u003cli\u003eMaterial: Ultrasuede® (Toray Industries)\u003c\/li\u003e\n\u003cli\u003eCushion type: Low-rebound foam\u003c\/li\u003e\n\u003cli\u003eWeight: 15.5 g per pad\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eCompatible models: T50RPmk4, T50RPmk4g, T60RP\u003c\/li\u003e\n\u003cli\u003ePackage contents: 2 ear pads (one pair)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"FOSTEX","offers":[{"title":"Default Title","offer_id":53693035938129,"sku":"59517","price":70.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/FostexEX-EP-RP-SUEDEEarPads.jpg?v=1777975210"}],"url":"https:\/\/wrdtunes.com\/collections\/fostex.oembed","provider":"Wired Tunes","version":"1.0","type":"link"}
