Sennheiser CH-700S is a balanced connection cable for the HDVD800 and HDVA600 headphone amplifier. In connection with the high-end headphones from Sennheiser, a top-class sound experience is guaranteed. Thanks to a four-pole plug, the cables are optimally matched to the fully symmetrical principle of Sennheiser headphone amplifiers and thus enable symmetrical signal transmission from the source to the headphones. The cables are made of oxygen-free copper (OFC). The CH 700 S and CH 800 S versions are also coated with silver, which further minimizes the resistance during sound transmission. The new high-end cables also have gold-plated contacts. On the amplifier side, a four-pin XLR connector with gold-plated Neutrik inserts ensures the best sound; at the other end of the cable are headphone-specific connectors.
