The DIANA headphones were launched in 2018 as a luxury line touted as the world’s thinnest boutique headphone. It has since changed longstanding perceptions of headphone physics by easily comparing to and in many cases besting the highest performance headphones. World-class sound in a compact portable package

ABYSS has since worked toward furthering this success, producing this second higher performance Phi version that’s ‘bigger on the inside’ by incorporating the Phi planar speakers from its flagship AB-1266 Phi CC.

This latest DIANA Phi headphone has world-class dynamics, resolution, and refinement to sound never before heard in such a compact package.

'Bigger on the Inside' best describes the Phi's huge sound, bass depth and speed, wide soundstage with impeccable tonal balance, voices so real you feel they are with you. 

Abyss CNC machines and finishes all aluminum frame components, produces its own planar speaker drivers, and skillfully assembled with US-made stainless hardware, all in its facility in Buffalo, New York, USA.
