Abyss headphones AB-1266 Phi CC


The Abyss AB-1266 Phi is the apex of the headphone world. Many years of development and research went into the making of what is considered the finest sounding headphone money can buy. Patent-pending ultra thin speakers deliver a most natural sound to your ears. 

From the very first note you will hear musicians and instruments in a whole new way. Voices appear out of nowhere and float in between your ears. Piano is in front of you to the left, singers in the center of your forehead while drums are slightly forward of them. No electronic tricks, simply the natural sounds of the recording coming through striking emotional chords, that's Abyss. The AB-1266 can convey the power of a huge symphony and the nuances of the quietest sounds in nature, a private concert for one.
