Combining Technology and Human Sensibility to Shape the Ultimate Sound

Oriolus is an audio brand established in 2015 with roots in Tokyo. Guided by the philosophy of “creating the ultimate sound,” Oriolus continues to develop a diverse range of products, from earphones and amplifiers to digital audio players and speakers, without being constrained by any particular category or technology.

At the heart of Oriolus’s engineering is Mr. Rao You Liang, an electronics engineer with many years of design experience. His career includes the development of OEM/ODM products for numerous manufacturers, including Denon and Marantz, as well as co-founding the company that would later become iBasso Audio. Drawing on his knowledge of acoustic theory and psychoacoustics, he validates circuit designs and acoustic structures through measurement data, while carefully refining component selection, listening tests, and tuning through repeated iterations.

Oriolus also incorporates a broad range of expertise into its product development, including insights into musical expression, vocal reproduction, and the diverse needs of audiophiles. This approach has contributed to the development of a wide range of products, including the flagship earphone Traillii JP, which has earned high praise from audiophiles around the world.

While engineering principles such as circuit design and acoustic analysis provide the foundation, Oriolus places equal importance on repeated listening and tuning. Our goal is to create a sound so natural and immersive that, before you realize it, you find yourself completely drawn into the music.

This is Oriolus’s philosophy of “creating the ultimate sound.”
