Sommer Cable is a German manufacturer of professional audio, video, and broadcast cables and connectors, founded in 1999 by Rainer Blanck and Friedhelm Sommer. Headquartered in Straubenhardt, Germany, the company produces its cables in-house in Germany and operates branches in Alsace, France and Santa Rosa, California. Its catalog spans more than 12,000 products covering bulk cable, connectors, premade cables, distribution systems, and electronics for the pro audio, broadcast, studio, A/V installation, and HiFi markets.

The company develops several in-house brands, including HICON connectors (introduced in 2001), the SYSBOXX modular distribution and stagebox system, the high-end EXCELSIOR cable series, and the water-resistant AQUA MARINEX line. Sommer Cable is widely used by sound engineers and live-sound rental companies for microphone, speaker, instrument, and multicore cabling, and its bulk cable is also a popular choice among boutique cable builders who assemble custom guitar and patch cables.

Beyond pre-assembled products, Sommer Cable's bulk cable stock — such as the SC-Spirit, SC-Galileo, and Club Series instrument cables — has become a staple in the DIY and small-shop cable-building community. The company also offers signature-series collaborations with professional musicians and supplies cabling for studios, broadcasters, and touring productions throughout Europe and North America.

Sommer Cable has 12 products cataloged on Equipboard, including Instrument Cables and Microphone Cables. Their gear is featured by 4 artists, with the strongest followings in Rock, Pop, and Folk, World, & Country. Notable users include Julian Wolf, Angus Young, and Svetlana Sibirjakowa.
