ABYSS Announces the Diana TC Signature Audiophile Headphones: CanJam NYC 2026
The engineers at ABYSS take their love of music to an extreme by incorporating coveted conceptual designs in precision CNC machining, head acoustics, and planar magnetic speakers into a new headphone entry: the Diana TC Signature.
According to ABYSS, the Diana TC Signature has the speed of a horn speaker (but using Planar drivers); a deep, airy, and layered soundstage with smooth, clear highs that extend out into space, a distinctive midrange, and vocals layered within the depths of the soundstage with deep and defined subwoofer bass.
The Diana TC Signature’s build quality is backed by a 10 year warranty and luxuriously appointed fine leathers and materials for all-day comfort. The TC Signature headphone deserves the highest level of electronics and cabling to compliment it’s nearly limitless resolution.
ABYSS Diana TC Signature Features
Stylish and Light: The is an ultra-slim, ultra-light boutique headphone sculpted from aircraft-grade aluminum for incredible strength.
Planar Drivers: The Diana TC Signature incorporates 63 mm planar speaker drivers that are built in-house and utilize a large high-tech neodymium magnet and ultra-thin planar speaker diaphragm to reproduce extremely fast transients and deep bass that goes down deep into the sub bass below 20 Hz (US patent #10,455,343). The sound is similar to a big speaker system with subwoofers, designed for a more intimate, personalized listening experience.
Open Back: The next generation CNC-machined frame assembly with open back tuned Fibonacci hole pattern maximizes bass response and extends openness and soundstage depth well outside of your head.
Headband: The Diana TC Signature features a high-end leather headband with Ultrasuede® sling suspension for all-day comfort. Magnetic wear-free headband size adjustments and low clamp force twist and flex headband that gently contours to any head, even with glasses.
Earpads: Pillow-top ear pads are hand-assembled in our US facility with a sculpted shape that conforms to your head shape with minimal clamp force. Comfort is exceptional. Ear pads are made with fine European lambskin, US-made foams, and include the bass ported option for enhanced bass response.
Finish: The Diana TC Signature integrates a high-tech oven-cured polymer-ceramic finish with Corning Gorilla Glass custom artisan inlay for long-term durability. In addition, the headphones come with a custom hard carry case with a velvet-lined interior. In addition, the face of each speaker is laser-engraved with model and serial number, and signed by the three designers Joe, Jason, and Eric Skubinski, hence the Signature nomenclature.
Optional Cable Set: Abyss suggests that users purchase the optional custom hand-made JPS Labs Superconductor HP headphone cable set. This upgrade is designed to maximize resolution and ergonomics with a soft, supple cable designed specifically for this headphone. JPS Labs has been making custom high-performance cables for over 30 years.

The Bottom Line
ABYSS is banking a lot on its technical prowess to attract customers to its $4,500 Diana TC Signature Audiophile Headphone, and it looks like it might be an uphill battle, as it has direct competition not only with Audeze LCD-5s (also priced at $4,500) but also with significantly lower-priced options, such as the Sendy Audio Egret, that have been well received.
Diana TC Signature is targeted at sound engineers, professional musicians, and experienced audiophiles with lots of spare cash who value accuracy, control, and long-term reliability. It is not for listeners seeking a lightweight and casual headphone solution.
