It is designed exclusively for the T60RPmk2 and T60RPmk2CL, which use the dual 2-pole 3.5 mm TS per-cup connection system introduced with the mk2 generation. The conductor is high-purity OFC, connectors are gold-plated, and the jacket is flexible PVC.\n\n\u003ch3\u003eT60RPmk2 earcup connector system and what it enables\u003c\/h3\u003e\nThe T60RPmk2 replaced the proprietary cup connector of the original T60RP with standard 2-pole 3.5 mm TS sockets on both left and right housings — one per cup, independent of each other. This design improves recabling compatibility across third-party and OEM accessories without adapters. ET-RP4.4BL2Y mirrors the dual-socket Y topology of the stock unbalanced cable while replacing the source-end 6.3 mm TRS with a 4.4 mm Pentaconn, completing a fully balanced signal path. Each channel runs on an isolated conductor pair from the earcup socket to the amplifier plug, with no shared ground at the Y-split. At the 50 Ω impedance of the T60RPmk2, this reduces common-mode noise and improves channel separation — measurable improvements on high-resolution source material and balanced DAC\/amp combinations.\n\n\u003ch3\u003eWhere ET-RP4.4BL2Y sits in the RP cable family\u003c\/h3\u003e\nThe original ET-RP4.4BL used a legacy termination for the first-generation T60RP and is now discontinued. The ET-RP4.4BL 2.0 uses a single 3.5 mm TRRS (4-pole) plug compatible with the T50RPmk4 and T60RP. The ET-RP4.4BL2Y uses two independent 3.5 mm TS (2-pole) plugs matching the T60RPmk2 and T60RPmk2CL dual-socket system. These cables are not interchangeable — the earcup connector geometry differs between generations.\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 — Y-cable topology, isolated channel connections\u003c\/li\u003e\n\u003cli\u003eHigh-purity OFC conductor — stable signal transmission across the frequency range\u003c\/li\u003e\n\u003cli\u003eGold-plated connectors at both ends — corrosion resistance and reliable electrical contact\u003c\/li\u003e\n\u003cli\u003eFlexible PVC jacket — consistent handling in studio and home environments\u003c\/li\u003e\n\u003cli\u003eCompatible with: T60RPmk2, T60RPmk2CL\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: ET-RP4.4BL2Y\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 (2-pole), gold-plated\u003c\/li\u003e\n\u003cli\u003eConductor: High-purity OFC (oxygen-free copper)\u003c\/li\u003e\n\u003cli\u003eJacket: Flexible PVC\u003c\/li\u003e\n\u003cli\u003eCompatible models: T60RPmk2, T60RPmk2CL\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"FOSTEX","offers":[{"title":"Default Title","offer_id":53693029679441,"sku":"59480","price":93.54,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/FostexET-TH4.4BL2YCable_29694855-966f-4be7-a7fe-94cc21e2301e.jpg?v=1777976893","url":"https:\/\/wrdtunes.com\/de-fr\/products\/fostex-et-rp4-4bl2y-cable","provider":"Wired Tunes","version":"1.0","type":"link"}
