The Connection to Perfect Sound.
CH 800 S / CH 700 S / CH 650 S Headphone amplifiers require good teamwork and the perfect connection. Thanks to their four pin plug, the CH 650 S, CH 700 S and CH 800 S high-end cables are optimally tuned to the fully symmetrical principle of the new Sennheiser HDVD 800 and HDVA 600 headphone amplifiers and allow for precise signal transmission with practically no distortion and without sound wave superposition.
