4 source(s) feeding this product's score.
Video reviews we found, each condensed to its verdict. They do feed the HearWiki score, at a measured weight below what a published written review carries.
11:15The reviewer finds the 64 Audio U12t to be an excellent all-rounder IEM with top-tier technical performance and detail retrieval, though it has a slightly rounded bass leading edge and a 3kHz dip that affects vocal openness. The included cable is subpar for the price, and the MX Apex module is not recommended, but the M15 and M20 modules are both enjoyable. Overall, it's a highly capable, clarity-first monitor that excels with complex music, though it lacks a 'party trick' and may not suit those preferring a warmer vocal presentation.
8:32The reviewer, who previously owned the U12t, now appreciates it more after evolving tastes and is considering repurchasing it. They praise its well-tuned, comfortable sound with excellent bass extension and treble, plus strong technicalities like detail retrieval and imaging, though they note a slight BA timbre and softened note edges. Overall, they give it a high recommendation as a forgiving flagship IEM.
10:37The reviewer considers the 64 Audio U12t the best-sounding IEM they've heard, praising its detail and soundstage as a worthy alternative to the HD 800, but is selling it because they've grown to prefer the more natural tonality of dynamic drivers over the balanced armature sound, despite acknowledging the U12t masks this well. They recommend it highly, especially on the used market.
