The XO brand began with the vision of Koichi Haido, Chief Instrument Technician at the Global Corporation in Japan. After many experiments and countless prototypes, the first XO trumpet was introduced to the market in 1995.

With vast experience in instrument making and prowess as a trumpet player, Haido continues to explore innovative approaches to meet perfection. He pushes the limits to reach the goal of providing a comfortable and enjoyable playing experience for every performer. Koichi hopes XO can empower musicians to deliver excellence in tone and performance for diverse musical genres, allowing players to easily achieve their own personal sound. Building upon the success and popularity of the original offering, XO works to continually expand its lineup with the development of exquisite and innovative instruments to support the artistic expression of every musician.
