It terminates in a 4.4 mm TRRRS (5-pole Pentaconn) plug at the amplifier end and two independent 3.5 mm TS plugs at the earcup end — the same dual-connector topology as the stock unbalanced ET-TH2.0UB2Y, implemented here in a fully balanced signal path. The jacket is flexible PVC, the length is 2.0 m, matching the factory cable.\n\n\u003ch3\u003eWhat balanced operation actually delivers with these headphones\u003c\/h3\u003e\nThe TH910 and TH919 run at 25 Ω; the TH1000RPmk2 and TH1100RPmk2 at 32 Ω — both impedances sit squarely in the operating range of reference-class balanced headphone amplifiers with 4.4 mm Pentaconn outputs, which have become the de facto standard in hi-end portable and desktop DAC\/amp units since adoption by Sony, Astell\u0026amp;Kern, and others. A balanced signal path eliminates common-mode noise induced by a shared ground return, which at the impedance levels of these headphones translates to improved channel separation and lower in-band noise floor on high-resolution source material. The two independent 3.5 mm TS plugs at the earcup end ensure each channel has a fully isolated signal path with no shared ground at the split point.\n\n\u003ch3\u003e7N OFC and signal path consistency\u003c\/h3\u003e\nFostex specifies 7N-grade OFC — 99.99999% purity copper — for both the internal wiring of the TH910\/TH919 and the supplied stock cables. Using the same conductor grade in the ET-TH4.4BL2Y keeps the external cable electrically consistent with the internal signal path. At the impedance levels of these headphones, any increase in conductor resistance from impurities is audible as a slight reduction in damping factor. Gold-plated connectors at both ends protect contact surfaces from oxidation under normal studio and listening conditions.\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4.4 mm 5-pole balanced Pentaconn (TRRRS) connector — fully balanced signal path\u003c\/li\u003e\n\u003cli\u003eTwo independent 3.5 mm TS earcup plugs — isolated channel connections, no shared ground at split\u003c\/li\u003e\n\u003cli\u003e7N-grade OFC conductor (99.99999% purity) — matched to TH910\/TH919 internal wiring spec\u003c\/li\u003e\n\u003cli\u003eGold-plated connectors — corrosion resistance and reliable electrical contact\u003c\/li\u003e\n\u003cli\u003eFlexible PVC jacket — consistent handling in studio and desktop environments\u003c\/li\u003e\n\u003cli\u003eCompatible with: TH910, TH919, TH1000RPmk2, TH1100RPmk2, TH810, TH818\u003c\/li\u003e\n\u003cli\u003eLength: 2.0 m\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: ET-TH4.4BL2Y\u003c\/li\u003e\n\u003cli\u003eType: Balanced, Y-cable\u003c\/li\u003e\n\u003cli\u003eSource connector: 4.4 mm TRRRS (5-pole Pentaconn), gold-plated\u003c\/li\u003e\n\u003cli\u003eHeadphone connectors: 2x 3.5 mm TS (mono), gold-plated\u003c\/li\u003e\n\u003cli\u003eConductor: 7N-grade OFC (99.99999% purity)\u003c\/li\u003e\n\u003cli\u003eJacket: Flexible PVC\u003c\/li\u003e\n\u003cli\u003eLength: 2.0 m\u003c\/li\u003e\n\u003cli\u003eCompatible models: TH910, TH919, TH1000RPmk2, TH1100RPmk2, TH810, TH818\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n","brand":"FOSTEX","offers":[{"title":"Default Title","offer_id":53693031416145,"sku":"59519","price":374.16,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/FostexET-TH4.4BL2YCable.jpg?v=1777976576","url":"https:\/\/wrdtunes.com\/en-fr\/products\/fostex-et-th4-4bl2y-cable","provider":"Wired Tunes","version":"1.0","type":"link"}
