B&S is a German brass instrument manufacturer based in Markneukirchen, in the Vogtland region known as the "Musikwinkel" (Music Corner), an area with a brass-making tradition spanning more than two centuries. The brand operates as part of Buffet Crampon Deutschland GmbH alongside sister brands Scherzer and Hans Hoyer, with production centered in a purpose-built brass instrument factory that opened in Markneukirchen in 1994.

The company's catalog covers Bb, C, D/Eb, and piccolo trumpets, cornets, flugelhorns, tenor and bass trombones, tenor and baritone horns, and a wide range of tubas. The Challenger and Challenger II trumpet families are among the most widely played B&S models, with variants like the 3137 and 3125 aimed at advanced and professional players. The X-Line tubas and the Meistersinger and PT-series instruments are aimed at the orchestral end of the catalog.

B&S instruments are used by classical, orchestral, and jazz players, with endorsers including Philip Cobb (BBC Symphony Orchestra), Mark Pender, Thierry Caens, and Alexis French. The brand sits in the step-up and professional segment rather than the student tier, and is distributed internationally through retailers such as Sweetwater, Music & Arts, and Guitar Center.
