Foundation Headphone Cable

FOUNDATION Series headphone cables are handmade in our California factory with cutting edge Synergistic Research technologies including Air String Geometries with pure 99.9999% Silver. Another trickle-down technology is our UEF Matrix Shielding that dramatically lowers your perceived noise floor.

With a full suite of SR Technologies, you hear resolution and holographic realism that’s never harsh or fatiguing, unlike most pure silver-based cables. In pulling all the stops, we applied a new High Voltage Treatment Process first developed for our Galileo SX World’s Reference Audio Cables. In short, we’ve created the worlds best headphone cables, and we’re confident you’ll love their sound over ANY headphone cable on the market regardless of price. So whether you’ve got a state-of-the-art headphone rig including upgraded headphone cables or if you’re a cable skeptic, FOUNDATION Series headphone cables will prove Synergistic Research is building the highest performance headphone cables on the planet. Now is the time to step up and take the FOUNDATION Challenge and find out just how good your current headphone system sounds with Synergistic Research.
