It uses 8x doubled 6N pure silver Air Strings for immediacy and presence on vocals, acoustic instruments, and complex passages, SRX XL Matrix Shielding with Graphene, and SRX XL High Voltage Conditioning, the same process developed for the flagship SRX XL cable line. Included Gold and Purple Carbon Tuning Discs let you further refine the cable's voicing. Available with a wide range of source and headphone-side connector options. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you match this cable to your specific headphone.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e8x Silver Air Strings, 99.9999% pure monocrystalline silver conductor\u003c\/li\u003e\n  \u003cli\u003eAir sealed \/ Teflon dielectric\u003c\/li\u003e\n  \u003cli\u003eSilver Braid shield, Quantum Tunneled SRX XL UEF Matrix Shield with Graphene\u003c\/li\u003e\n  \u003cli\u003eSRX XL High Voltage Conditioning treatment\u003c\/li\u003e\n  \u003cli\u003eIncluded Gold and Purple Carbon Fiber UEF Tuning Discs\u003c\/li\u003e\n  \u003cli\u003eSource connectors: 4-pin XLR or 3.5mm (with included 6.35mm\/1\/4\" adapter); dual 3-pin XLR available (+$100)\u003c\/li\u003e\n  \u003cli\u003eWide range of headphone-side connector options — see below\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eConnector Options\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eSource connectors:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e4-pin XLR\u003c\/li\u003e\n  \u003cli\u003e3.5mm (includes 6.35mm\/1\/4\" adapter)\u003c\/li\u003e\n  \u003cli\u003eDual 3-pin XLR (+$100)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHeadphone-side connectors:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e2-pin Lemo (Focal Utopia)\u003c\/li\u003e\n  \u003cli\u003e3-pin Lemo\u003c\/li\u003e\n  \u003cli\u003eMMCX (Pioneer SR-Master1; Shure SRH1540, SRH1840)\u003c\/li\u003e\n  \u003cli\u003eSennheiser Push-Pull (HD820, HD800S, HD800)\u003c\/li\u003e\n  \u003cli\u003eSennheiser 2-pin (HD650, HD600, HDXX)\u003c\/li\u003e\n  \u003cli\u003eMr. Speakers 4-pin Hirose (Aeon, Ether 2, Ether 2 Closed, Flow, Flow Closed)\u003c\/li\u003e\n  \u003cli\u003e4-pin Mini XLR (Audeze LCD4, 3, 2, X, XC; Meze Empyrean; ZMF Atticus, ZMF Eikon)\u003c\/li\u003e\n  \u003cli\u003e3-pin Mini XLR\u003c\/li\u003e\n  \u003cli\u003e2.5mm Mono (Hifiman older styles)\u003c\/li\u003e\n  \u003cli\u003e3.5mm Mono\u003c\/li\u003e\n  \u003cli\u003e3.5mm Stereo (Hifiman Ananda, Susvara, HE1000, HE400i, HE500, HE6, HE650)\u003c\/li\u003e\n  \u003cli\u003e8-contact\u003c\/li\u003e\n  \u003cli\u003eSMC\u003c\/li\u003e\n  \u003cli\u003eTRRS (2.5mm and 3.5mm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAdditional connections may be available upon request — always confirm your headphone's connector with Vinyl Sound before ordering.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eConductors\u003c\/td\u003e\n\u003ctd\u003e8x Silver Air Strings, 99.9999% pure monocrystalline silver\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDielectric\u003c\/td\u003e\n\u003ctd\u003eAir sealed \/ Teflon\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eShielding\u003c\/td\u003e\n\u003ctd\u003eSilver Braid, Quantum Tunneled SRX XL UEF Matrix Shield with Graphene\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTuning discs included\u003c\/td\u003e\n\u003ctd\u003eGold and Purple Carbon Fiber UEF Tuning Discs\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePoint-to-point connections\u003c\/td\u003e\n\u003ctd\u003e8 hand-soldered\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSilver solder content\u003c\/td\u003e\n\u003ctd\u003e4%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHand-build time\u003c\/td\u003e\n\u003ctd\u003e2 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBurn-in\u003c\/td\u003e\n\u003ctd\u003e5-day, 2-step process\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStandard length\u003c\/td\u003e\n\u003ctd\u003e1 meter (additional length available, +$300\/0.5m)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWill this cable fit my headphones?\u003c\/strong\u003e\u003cbr\u003e\nFoundation XL Headphone Cable supports most popular headphone connectors, including Focal, Sennheiser, Audeze, Hifiman, Shure, Meze, and ZMF.
