FATFreq Grand Maestro VS 64 Audio Volur

Youtube Video Summary

64 Audio Volür comes across as a tour-de-force of bass tech: dual true isobaric dynamic drivers deliver deep, textured rumble with a “speaker-in-the-room” feel, while the Tia BA adds pronounced upper-treble energy. Ergonomics are excellent—compact metal shells, smooth nozzles that take tips well, and a best-in-class top two-pin connection that makes cable swaps effortless. Build feels built-to-last and the purple faceplate looks classy, though a more varied aesthetic across 64 Audio’s lineup would be welcome.

The APEX modules change flavor more than fundamentals: M20 adds a touch more bass, M15 strikes the best balance, M12 runs leaner, and MX is very flat and generally skippable; running it empty is a hard no. On music, Volür shines with EDM/modern productions, projecting holographic low-end and vivid dynamics; in dense mixes with strong instrumentals and vocals, the midrange can feel overrun and less engaging. Versus peers: U4s tracks similarly in bass level (with different modules), Elysian Annihilator brings stronger 3 kHz vocal presence while Volür counters with superior bass texture, and Monarch MKIII sounds more overtly U-shaped with greater mid/upper energy.

As a package, this is a fantastic IEM—arguably a favorite from 64 Audio—yet not flawless. The price is steep, the APEX ecosystem feels like paid tuning switches, and there’s some treble peaking plus occasional vocal thinness; a simpler, cheaper, M12-style fixed tuning would be a dream. For listeners prioritizing hip-hop, rap, and modern genres, Volür can absolutely be endgame; for vocal-centric or classical libraries, it’s impressive but not definitive. Overall verdict: a five-star recommendation for those who can afford it, anchored by class-leading bass and exceptional build, with clear trade-offs noted.
