Bang & Olufsen is a Danish high-end audio company founded in 1925 by Peter Bang and Svend Olufsen in Struer, Jutland. The company began by designing radios that ran on alternating current rather than batteries, and has since become known for combining engineering with sculptural industrial design. Its products span loudspeakers, headphones, turntables, and televisions, often produced in aluminum, wood, and fabric finishes that have made the brand a fixture in design museums.

The Beolab line includes flagship active loudspeakers such as the Beolab 90, Beolab 50, Beolab 28, Beolab 20, Beolab 19, and Beolab 8. The Beoplay range covers personal audio, including the Beoplay H100 over-ear headphones, Beoplay EX wireless earbuds, and Beosound A5 portable speaker. Historic models like the Beosound 9000 CD player and various Beogram turntables remain collector items, and B&O also supplies premium in-car audio systems for automakers including Audi, Aston Martin, and Ford.

While B&O is positioned more toward consumer hi-fi and lifestyle audio than studio gear, the company maintains a presence in the audiophile community through its active digital loudspeaker technology, beam-width control, and room-correction systems. Its design language—originally shaped by long collaborations with designers such as Jacob Jensen and David Lewis—has influenced how high-end audio products are presented as objects as much as instruments.

Bang & Olufsen has 11 products cataloged on Equipboard, including Headphones & In-Ear Monitors, Active & Passive Monitors, and Speakers & Accessories. Their gear is featured by 3 artists, with the strongest followings in Electronic, Rock, and Hip Hop. Notable users include Skrillex, Madeon, and DJ Khaled.
