Abyss AB-1266 Phi TC Headphones

Introducing the new AB-1266 Phi TC (Total Consciousness). Newly designed 66 mm planar magnetic speaker drivers deliver the highest resolution of any headphone ever made. Combined with the venerable AB-1266 headphone design, newly minted all-aluminum frame and posh earpads mean you’ll never have to buy another concert ticket.

A brand new generation of ABYSS planar speakers, these latest drivers offer unprecedented levels of clarity and resolution to sound, without the typical brightness or harshness. 

This latest Ceramic Coated version sports a high-tech, durable two-tone polymer ceramic coating on the all-metal frame along with newly designed ear pads for greater comfort and improved sound quality.

Standard Package: Includes 8-foot (2.5 m) balanced 4-pin XLR cable & flexible 1/4" (6.3mm) adapter custom-made by JPS Labs & velvet bag with embroidered Abyss logo.

Complete Package: Includes the same leather carrying case and headphone stand that's included in the Deluxe Package, but the included cable is the JPS Labs Superconductor HP dual balanced 3-pin XLR cable set (a $3000 cable if purchased separately)
