Recommendations

For reliable performance, use the extension cable within its specified length and avoid exposure to excessive heat, liquids or mechanical stress. Check compatibility with your specific Poly or HP headset and base model before purchase to ensure proper QD connector matching. Periodically inspect connectors for wear and debris and replace the cable if audio quality degrades or physical damage appears.
