The Foundation SX family combines a coherent hi-fi cable design approach with different purpose-built connections for analogue, digital, power and loudspeaker applications.\u003c\/p\u003e\u003ch3\u003eManufacturer construction and technology\u003c\/h3\u003e\u003cp\u003eSynergistic Research brings its Foundation SX cable principles, including proprietary UEF Matrix treatment and extended conditioning, to a flexible headphone connection. The final cable configuration must account for the headphone's own sockets and the output format of the source equipment.\u003c\/p\u003e\u003cp\u003eThe manufacturer describes a graphene-associated UEF shielding treatment and extended high-voltage conditioning developed through work on its higher-end SRX series. These design choices are intended to control electrical interference, with listening results depending on the complete system.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart of the Synergistic Research Foundation SX cable collection\u003c\/li\u003e\n\u003cli\u003eDedicated headphone cable application\u003c\/li\u003e\n\u003cli\u003eProprietary manufacturer UEF treatment and conditioning\u003c\/li\u003e\n\u003cli\u003eConnection and length requirements dependent on the intended equipment\u003c\/li\u003e\n\u003cli\u003eCurrent UK RRP and selectable options retained as displayed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility and choosing the right cable\u003c\/h3\u003e\u003cp\u003eThe current listing provides 3.5mm, 6.35mm and four-pin XLR amplifier-side options, but the headphone-side plugs must also be confirmed. A balanced headphone lead requires an amplifier with an appropriate balanced output and correct wiring; connectors must not be chosen by appearance alone.\u003c\/p\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003eDoes a four-pin XLR plug make any amplifier balanced?
