Synergistic Research Foundation SX Headphone Cable

Synergistic Research Foundation SX Headphone Cable

A replacement headphone lead for compatible high-fidelity headphones and headphone amplifiers, offered with different amplifier-side connections. The Foundation SX family combines a coherent hi-fi cable design approach with different purpose-built connections for analogue, digital, power and loudspeaker applications.

Manufacturer construction and technology

Synergistic 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.

The 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.

Key features

• Part of the Synergistic Research Foundation SX cable collection
• Dedicated headphone cable application
• Proprietary manufacturer UEF treatment and conditioning
• Connection and length requirements dependent on the intended equipment
• Current UK RRP and selectable options retained as displayed

Compatibility and choosing the right cable

The 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.

Common questions

Does a four-pin XLR plug make any amplifier balanced? No. The amplifier must have an appropriate headphone output.
