Introducing the Younger Sibling of the Headonia 300B

Experience the next level of audio performance with the Ultima 88,

headphones, offering a distinctly different sound profile from its older sibling,
the Headonia 300B.

because we love them both equally,
it's clear that each amplifier appeals to a different audience.
