    FiR Audio was founded in 2018 by two brothers, Bogdan and Alex Belonozhko and their friend Daniel Lifflander. Between them they have over 20 years of experience in designing and manufacturing some of the most advanced in-ear monitors while they were at 64 Audio. At FiR Audio, they are able to produce the next generation of IEM products, again pushing the boundaries of IEM technology.

    In 2021 FiR Audio released the Frontier Series, which includes the flagship Xenon 6, Krypton 5, and Neon 4 models. Packed with revolutionary technologies such as Kinetic Bass, a hybrid conduction technology which enables a very rich and natural bass, ATOM XS, the next generation ATOM module, Open Acoustics System, with Open Drivers that don’t use sound tubes, and Rigid Technologies that provide industry leading durability and serviceability of the IEMs. The Frontier Series comes in both Custom-Fit and Universal-Fit models.
