Abyss – Diana Phi
The Abyss – Diana Phi headphones were launched in early 2018 as a luxury line touted as the world’s thinnest boutique headphones. It has since changed long-held perceptions of headphone physics by easily comparing to, and in many cases outperforming, the best-performing headphones. World-class sound in a compact portable package.
ABYSS has since worked toward furthering this success, producing this second higher performance ‘DIANA Phi’ version that’s ‘bigger on the inside’ by incorporating the Phi planar speakers from their flagship AB-1266 Phi CC.
The new DIANA Phi headphone has world-class dynamics, resolution, and refinement to sound never before heard in such a compact package. As with any ABYSS, she’s quite capable of playing any genre of music to an extreme level of enjoyment, limited only by the electronics and recording.
