Monoprice is an American online retailer headquartered in Rancho Cucamonga, California, founded in 2002 with a mission to provide high-quality electronics and accessories at significantly lower prices than traditional retail brands. The company initially gained a reputation for selling affordable HDMI cables and audio cables, challenging the markup practices common among big-box retailers, and has since expanded into a vast catalog of consumer electronics, networking equipment, home theater gear, and office accessories.
Monoprice operates several in-house brands including Monoprice Select, Dark Matter (gaming peripherals), Strata Home (appliances), and Stage Right (musical equipment and pro audio). The company sells directly to consumers through its website, cutting out middlemen to keep prices low. Their product range includes monitors, 3D printers, headphones, speakers, cables, adapters, networking hardware, and TV mounts, with a strong focus on value-oriented alternatives to premium brands. Monoprice also offers a lifetime warranty on many of its cable products and a 30-day money-back guarantee on most items.
