TRUTHEAR PURE is a newly released in-ear monitor featuring a refined hybrid configuration that combines one dynamic driver with three balanced armature drivers. Designed for personal use, it offers excellent isolation and delivers high-quality sound. Building on the legacy of the HEXA development, TRUTHEAR PURE offers notable improvements across the audio spectrum — with enhanced bass response, rich mids, and crisp, detailed highs, all presented with a well-balanced and transparent sound signature.
The design uses a dynamic driver with a composite membrane made of silicone suspension and a liquid crystal polymer dome. The diameter of this driver is 10 mm, and the magnetic system is a double chamber with N52 magnets. This approach allows you to lower your own resonant frequency and increase impedance, making the bass sound denser and more controlled, while maintaining the accuracy of frequency separation.
The mid-frequency and partially high-frequency range is served by a special full-band armature driver, different from the one used in HEXA. This element ensures a tight and consistent connection with the bass part, taking into account the measurements of HRTF characteristics according to the BK5128 standard. For the highest frequencies, a modified driver based on the WBFK series is used, which increases the resolution and extends the range upwards.
Particular attention is paid to the structure of the nozzle with a filtering function, made using DLP 3D printing with high precision. This made it possible to implement a three-way crossover with carefully calculated RC circuits, due to which each of the four drivers strictly performs its role. This system helps to bring the measured characteristics closer to the design curve.
The TRUTHEAR PURE body is made of medical transparent resin using DLP 3D printing (HeyGears). The material is skin-friendly, the body remains lightweight and reliable, and thanks to the internal painting and careful grinding, it has a neat appearance. At the same time, the pressure in the body is optimized, and its dimensions are reduced for more comfortable wearing.
A reliable universal 0.78 2Pin connector (deep fit) is used for connection, and a cable made of oxygen-free copper with silver coating is included in the kit. This design maintains high sound quality and gives freedom to experiment with replacing cables.
TRUTHEAR PURE demonstrates high phase coherence across the entire frequency range. This eliminates typical problems of hybrid systems, providing a more natural sound without distortion associated with phase mismatches. The model is suitable for various scenarios – from monitoring and listening to music to games, maintaining accurate and natural reproduction on all three bands.
