Product Description

Abyss Diana Phi Headphones brings the award-winning sound of the flagship AB-1266 Phi CC into the realm of the worlds thinnest boutique headphone.


Bigger on the Inside best describes the huge sound, bass depth and speed that is second only to the bigger AB-1266. You'll experience wide soundstage with impeccable tonal balance and voices so real you feel they are with you. Diana Phi plays her heart out for you every time.


Diana is engineered to play the delicate nuances of piano and violin yet pelt out clean powerful crescendos when called upon. Abyss began with their world-class AB-1266 Phi headphone and worked to develop a new speaker transducer customised for the thin lightweight profile of Diana.

Retaining the amazing speed and impact of the large AB-1266 Phi while miniaturising the entire headphone package proved to be a huge engineering challenge. Abyss spent two years toggling between Solidworks 3D software and machining prototypes to reach a point where she could be no thinner.


Large 63mm patent pending Phi planar drivers with ultra-low mass diaphragm delivers extremely fast bass impact and subtle lifelike details to music. Open back means more of a sense of space and you-are-there realism, with a positive benefit of allowing you to still hear your surroundings while on the go.

Lower volume settings let you carry on a conversation with others while playing relaxing background music, raise the volume to dissolve outside noise. The proximity of Diana’s natural sounding speakers to your ears allows the brain to focus on music with an illusion of floating outside of your head.


Being material experts allows Abyss to fine-tune the room to offer up speaker like performance around your head, to sound as if you are seated next to the band. Acoustics are huge with headphones, they’re like tiny rooms for your ears. The open back Fibonacci hole pattern was tuned to match Diana’s speaker drivers perfectly, allowing her to breathe like life itself. Thin is in with Diana, and every one of her sculpted curves is purpose-built for good looks and great sound.

Great Design

Each Diana is machined, finished and carefully hand assembled in New York using the finest materials, laser engraved with signature model and serial number. Feel this headphone in your hands to appreciate the quality of Abyss. As with any Abyss design, longevity and lack of moving parts are very important traits for final sound quality to prevent squeaks and the need for repair.

This is the thinnest boutique headphone sculpted from 1Kg of aircraft grade aluminium that is transformed into a frame structure under 100g once the CNC machine completely removes every last bit with smooth accuracies measured in fractions of a thousandth of an inch. A high-tech hard polymer ceramic Titanium Gray finish adds style and elegance.

Ultra Comfort

The incredible strength and ultra-rigidity this provides is paired with a soft breathable leather, as found in the finest of sports cars, and Italian Alcantara for ultimate comfort. Diana's sliding headband design has been optimised over many months while observing fit on hundreds of different heads to a point where she can adapt to nearly any head shape. Diana is equipped with an EMotion flexible magnetic headband that adjusts smoothly and cradles your head comfortably without pressure while lambskin ear pads are interiorly contoured to cradle your ears. You’ll completely forget you are wearing headphones.

Easy Travel

USA-made dual zipper canvas carry case with leather accents and accessory pockets makes it easy to carry Diana with you on your travels. It is packaged with JPS Labs cables in 1.5m length with a choice of 3.5mm, 2.5mm balanced, 4 pin XLR or 4.4mm balanced plug (Additional cables may be purchased separately).
