  • Solid 32AWG OFC conductors,
  • Induction soldered pin transitions for benchmark inter-terminal uniformity,
  • Anti-fatigue Die-cast Zn alloy connectors tested to >l1,000 cycles & 2kg retention force,
  • 100% of units tested on the production line for NIL Bit Error Rate (BER) @ 340Mcsc, <0.05% in-field failure rate,
  • Halogen free construction,
  • Limited lifetime warranty,
  • Licensed HDMI 2.0 Adopter company.


THX Certified

THX® Certification involves a rigorous suite of some 75 tests over and above the HDMI® Compliance Test Specification (CTS), including tests for high bandwidth stability to 18Gbps (aggregate data rate), dependable interoperability, benchmark connector fit and overall premium build quality.

It's the most comprehensive cable test regime onthe planet, certifying cables as the best available. Read more about the THX Interconnect Certification programhere.

Darbee Certified

DarbeeVision Inc. is the creator of Darbee Visual Presence™ (DVP), the visual perception processing methodology as featured in their DVP-5000 Darblet and DVP-5100CIE (Custom Installer Edition) stand-alone devices, and is also integrated into the premium 'D' series Oppo Blu-ray players for the best possible picture quality.

Darbee have uniquely certified the Kordz R.3 HDMI cablefor its robust connection, signal transfer accuracy and shielding properties.

This ensures fully tested FCC (Federal Communications Commission) compliance not only at the Darbee HDMI port, but at the far end of the interconnect for high integrity delivery of the processed signal to the display.
