The AB1266 TC is a flagship open-back planar magnetic headphone featuring newly designed 66 mm drivers for high resolution and clarity, with an all-aluminum frame and comfortable lambskin ear pads. It is designed, machined, and hand-assembled in New York, USA, and requires a high-quality amplifier for best performance.
The Abyss AB-1266 TC is a premium open-back planar magnetic headphone that delivers exceptional sound quality, but it requires a powerful amplifier to perform at its best. As a significant redesign of the AB-1266 line with a new driver, it represents the pinnacle of the series with a reference-level audio experience. Its moderate impedance makes it more accommodating to a wider range of high-end amps, though its price and power needs firmly target audiophile enthusiasts.
