Embeds 1 Dynamic Driver & 3 Balanced Armature For High-Quality Audio

Truthear PURE features a 1DD + 3BA hybrid setup designed for a balanced and detailed sound. The 10mm dynamic driver uses a silicone suspension, LCP dome diaphragm, and a dual-cavity magnetic circuit with an N52 rubidium magnet, along with a specialised copper voice coil to deliver punchy, controlled bass and lower resonance. A custom composite BA driver handles the mids and part of the treble, tuned using HRTF data from BK5128 HATS for accurate response. For the upper treble, a WBFK-style BA driver extends high-frequency detail and airiness without harshness, ensuring a clean and natural presentation across the full range.

Features 3-Frequency Crossover Nozzle Structure For Clean Sound

Truthear PURE incorporates a precisely tuned three-frequency crossover network, supported by a high-precision RC circuit and damping optimisation. Its nozzle structure is manufactured using advanced DLP 3D printing, allowing for integrated filtering functionality and optimal sound channeling. Each of the four drivers is routed through dedicated nozzles that ensure they operate efficiently within their intended frequency ranges. This engineering approach brings the earphone’s real-world performance closer to its acoustic design goals, delivering balance, clarity, and coherence across the lows, mids, and highs.

Precise Audio Via Accurate Tuning & Maintains High Phase Consistency

Truthear PURE achieves superior tuning and objective performance by refining driver integration, crossover design, damping, cavity structure, and cable configuration. These optimisations reduce treble resonance peaks, improve bass control, and result in a cleaner, more natural sound. Compared to the HEXA, PURE delivers deeper bass, fuller mids, and brighter, more detailed highs, ideal for music, gaming, and monitoring. It also maintains high phase consistency across all frequency bands, ensuring accurate imaging, a natural soundstage, and eliminating distortions often found in typical multi-driver IEMs.

Meticulously Crafted By HeyGears Utilising High-Quality Materials

Truthear PURE features a precision DLP 3D-printed cavity, crafted by HeyGears using medical-grade, high-transparency resin with internal colouring and fine surface treatment for a refined look. This advanced printing process enables complex internal structures like precision nozzles and vents, resulting in a lightweight, durable, and skin-friendly shell with excellent acoustic performance. Building on the ergonomic design of the HEXA, PURE combines angular and rounded shapes for a sleek yet practical form. It features an optimised pressure vent and a more compact housing, ensuring a secure and comfortable fit even during long listening sessions.

Comes With Premium Copper Silver-Plated Detachable Cable

Truthear PURE comes equipped with a premium copper silver-plated coaxial cable. Designed to complement the tuning of the IEMs, this oxygen-free cable enhances clarity and detail while maintaining flexibility and durability. It uses a recessed 0.78mm 2Pin connector, allowing users to swap cables easily and explore various upgrades, balanced connections, or Bluetooth modules.
