With tia tech, Wave Sync and a semi-open apex chassis, 64 Audio’s clean, resolving, easy-sounding Duo delivers a much-needed jolt to the kilobuck category.
If you enjoy a gorgeous, organic tonality and don’t mind a slightly laid-back midrange, the U6t is an auditory delight and a fully formed high-end IEM experience.
64 Audio’s A18s is about as natural as reference gets; a warmer, mellower, more engineer-tailored take on their custom flagship that’s discerning all the same.
