DH Labs USB Digital Audio Cables 0.5 meters by Silversonic Our new USB cable combines top quality materials with precision manufacturing and solid engineering. DH Labs uses silver-coated OFHC copper conductors insulated in a low-density gas-injected dielectric. Our USB Cables maintain a highly uniform characteristic impedance, which minimize signal reflections (and thus cable induced jitter). We use 100% shield coverage (the shield is also wrapped at constant tension, to avoid "VSWR spikes") and top quality connectors. The DH Labs USB cable is available in lengths from 0.5 meters to 5.0 meters.
