The ABYSS AB-1266 Phi TC is an open-back planar magnetic headphone engineered to deliver uncompromising reference performance. Designed and manufactured in New York, USA, it incorporates ABYSS’s latest Phi TC planar driver technology together with a highly adjustable frame that allows the acoustic interface between the ear and driver to be optimised for each listener. This unique approach enables exceptionally deep bass extension, expansive soundstaging and remarkably low distortion.
Custom 66mm planar magnetic drivers, a precision CNC-machined aluminium frame and an ultra-low-resonance driver structure contribute to its clarity, transient speed and precise retrieval of musical detail. Its open-back design, adjustable fit system and compatibility with high-quality headphone amplifiers allow the AB-1266 Phi TC to reproduce recordings with exceptional scale, dynamics and transparency.
