Hybrid In-Ear HeadphonesHigh-performance in-ear headphones featuring a hybrid design combining a dynamic driver and three balanced armature driversFeaturing a polyurethane suspension, a composite liquid crystal dome diaphragm, and a dynamic driver with a dual-chamber design and an internal magnetic circuit made of N52 magnetFeaturing a DLP 3D-printed housing, as commonly used in high-end multi-driver headphones and custom-fit in-ear headphonesEquipped with a silver-plated copper cable‍Efficient driver configurationHEXA is an in-ear headphone featuring a hybrid structure consisting of one dynamic driver and three balanced armature drivers. The original intent of the design is to achieve this goal through a simple, sensible, and efficient configuration, offering users a sophisticated hybrid headphone at an affordable price.‍A special 10-mm dynamic driver handles the bass. The sophisticated internal magnetic circuit is equipped with a flexible polyurethane suspension material and an LCP liquid crystal dome diaphragm, in line with the Truthear ZERO concept. A unique weighted voice coil serves to lower the natural resonance frequency and moderately increase the impedance, enabling it to produce the most powerful bass and meet the requirements for precise frequency distribution.A full-range balanced armature driver made of composite material handles the midrange, which can be precisely tuned to the frequency band of the dedicated dynamic driver; the high-frequency band also closely matches HRTF characteristics and comes very close to the intended sound signature.‍A custom-made balanced armature driver, similar to the WBFK series, handles the treble. It not only complements the frequency range but also, thanks to its fine craftsmanship, gives the HEXA a smooth, clear high-frequency response.‍Precise hybrid frequency divisionThe acoustic waveguide structure with a filtering function, realized through high-precision DLP 3D printing technology, and the RC frequency division achieved through precise calculations ensure that the four drivers function well under their respective acoustic waveguides, bringing the HEXA’s objective index closer to the design target.‍Excellent measurement resultsHEXA features appropriate bass boost and a high-frequency amplitude response that covers specific HRTF characteristics. Although the bass boost is lower than that of the Truthear ZERO, HEXA offers more adequate bass reproduction thanks to its special dynamic driver, and the transition between bass and midrange is more natural. The treble on the HEXA is very distinctive; it offers a completely different listening experience with different ear tips: with silicone ear tips, the sound is clearer and more natural, while with foam ear tips, some high-frequency resonance peaks are suppressed, making the sound softer and more refined. The different performance also affects the frequency response.Just like the ZERO, the HEXA maintains the same phase across the entire frequency range, and none of the connection issues common in conventional multi-driver earphones occur, resulting in a natural sound without phase distortion.‍Next-generation DLP 3D printing technologyHeyGears’ DLP 3D-printed housing features a proprietary high-transparency, medical-grade resin, internal coloring, and a fine surface polishing process. It enables complex, intricate sound guide structures while ensuring printing accuracy and efficiency. At the same time, it ensures a lightweight, well-fitting housing and guarantees skin-friendly and reliable materials.‍A brand-new, striking, and reliable ID designHEXA features a square yet sleek ID design that minimizes the housing volume as much as possible while ensuring wearability to achieve a lighter weight. It features a CNC-machined, anodized, and sandblasted metal front plate that reduces contact with the ear, thereby alleviating pain caused by prolonged wear.Furthermore, the aluminum alloy front plate is secured with self-tapping screws and fixed with adhesive, eliminating the risk of it accidentally falling out.‍High-Quality Cable + Extensive Customization OptionsFour strands of high-quality silver-plated cable, combined with the universal 0.78 mm 2-pin plug (the earcup features a recessed 0.78 mm 2-pin jack), ensure excellent sound quality. At the same time, the replaceable cable design offers endless possibilities.Technical SpecificationsName: TRUTHEAR HEXADriver: 1DD+3BA hybrid driverDynamic driver diaphragm: PU+LCP composite diaphragmImpedance: 20.5 Ω ±15% (@1 kHz)Sensitivity: 120 dB/Vrms (@1 kHz)THD: THD ≤ 1% at 1 kHz (94 dB)Frequency response: 8–40 kHz (IEC 61094, free field)Effective frequency response: 20–20 kHz (IEC 60318-4, -3 dB)‍Package contentsTRUTHEAR [HEXA] * 1High-quality silver-plated cableEar tips * 3 pairs (S, M, L) (thick diameter)Ear tips * 3 pairs (S, M, L) (thin diameter)Foam ear tips * 1 pair (M)User manual * 1Warranty card * 1‍

It features a sophisticated internal magnetic circuit structure, paired with a diaphragm made of silicone gel (for the suspension) and LCP material (for the dome). Unlike the copper-clad aluminum commonly used in dynamic woofers, this model employs a special copper coil. This choice helps lower the natural resonance frequency and appropriately increase the impedance, enabling powerful bass that meets the requirements of a precise crossover.For the midrange and part of the high-frequency range, a composite full-range balanced armature driver—different from the one used in the HEXA model—is employed. This driver is designed to provide a precise transition to the frequency band of the dedicated dynamic driver, ensuring that the high frequencies closely align with the intended design goals based on the HRTF characteristics measured with the BK5128 HATS.PURE optimizes the crossover and damping characteristics. By employing a custom-designed balanced armature driver, similar to the WBFK series, for the high-frequency range, extension in the upper high-frequency range is improved, and both resolution and information transmission for these frequencies are optimized, while simultaneously complementing the overall bandwidth.‍Precise hybrid three-way crossoverPURE’s nozzle design, which incorporates a filtering function, is manufactured using high-precision DLP 3D printing technology. This design, combined with a precisely calculated RC crossover, results in a hybrid three-way crossover system that allows each of the four drivers to effectively fulfill its respective role under the corresponding nozzles. This advancement helps bring PURE’s objective measurement values closer to the intended design goals.‍Outstanding objective measurementsPURE has made significant adjustments to various components of the audio system, including the crossover, drivers, damping, resonance chamber, and cabling. These modifications aim to reduce the Q-factor of the resonance peak in the upper high-frequency range while optimizing bass response for a better listening experience.The PURE delivers a solid, natural sound that is versatile enough for various applications, including monitoring, music, and gaming.

In-ear headphones with two dynamic driversTwo dynamic drivers (10 mm and 7.8 mm)Redesigned driverDLP 3D-printed housingNewly developed 2-pin silver-plated copper cable‍Improved configuration, increased efficiencyLike its predecessors in the ZERO series, the ZERO:BLUE2 also features two dynamic drivers. However, the structure of the 7.8 mm dynamic driver has been modified, with a focus on the mid and high frequencies. This driver utilizes a sophisticated internal magnetic circuit structure that incorporates flexible polyurethane material for the suspension and an LCP (liquid crystal polymer) dome diaphragm. Despite these similarities, the internal design differs significantly from earlier models.Truthear has achieved a significant breakthrough by increasing the diameter of the magnet for the 7.8-mm driver by approximately 25%. Additionally, we have expanded the dome surface area by about 50% and improved the conductive structure in the high-frequency range. Although these changes make the manufacturing and processing of this dynamic driver more challenging, they increase conversion efficiency and significantly improve sensitivity in the upper high-frequency range.This advancement not only meets our research and development requirements but also results in objectively superior measurement values, leading to a smooth, transparent high-frequency range with improved extension and excellent resolution.In addition, the 10-mm dynamic driver responsible for the bass frequencies has also been improved. The newly tuned suspension made of rigid silicone is matched to the liquid crystal dome diaphragm and features a voice coil with an ultra-thin wire diameter, creating an entirely new bass tuning system.This system utilizes a low-distortion crossover design, similar to that of the ZERO:RED, resulting in significantly improved objective measurement values, such as lower nonlinear distortion compared to the original ZERO. As a result, users can expect deeper and more powerful bass reproduction.‍Hybrid Multi-Frequency CrossoverTruthear has redesigned the cavity structure and low-distortion crossover based on valuable experience and user feedback from previous models featuring two dynamic drivers. This redesign aims to improve the conversion efficiency of the dynamic drivers while allowing each driver to fulfill its respective role. As a result, Truthear has significantly improved sensitivity. The filtered nozzle, precisely printed by HeyGears using high-precision 3D DLP technology, works in conjunction with a mixed multi-frequency crossover to bring the ZERO:BLUE2’s objective measurement values closer to the intended design goals.‍Outstanding objective measurementsThe research and development goal of the ZERO:BLUE2 represents a departure from previous TRUTHEAR products. The aim is to increase overall conversion efficiency while maintaining excellent performance in both linear and nonlinear distortion.Nonlinear distortion: The ZERO:BLUE2 not only meets Truthear’s R&D goals but even outperforms the RED in certain frequency ranges regarding nonlinear distortion. It delivers a clean background and effectively restores details, enabling precise reproduction of the musical sound.Linear distortion: The frequency response curve targeted by the ZERO:BLUE2 is designed to better match the audience’s preferences. We have optimized reproduction in the low-bass range (below 50 Hz) through various measures, ensuring a smoother transition into the mid-frequency range. The high frequencies are closely matched to the amplitude response characteristics of HRTF, maintaining high sensitivity above 10,000 Hz.These improvements have significantly optimized ZERO:BLUE2 compared to the performance metrics of ZERO. In terms of the subjective listening experience, it offers a more dynamic and lively sound than RED, with excellent conversion efficiency in the high-frequency range that reveals the subtle details in recording and mixing processes.Furthermore, ZERO:BLUE2 features extremely consistent phase characteristics across the entire frequency range, effectively eliminating the unnatural listening experience often caused by phase distortion.‍Optimized DLP 3D Printing MaterialsThe shell of the ZERO:BLUE2 continues to benefit from the high-quality 3D DLP services of the trusted brand HeyGears. The new model retains the design of the original ZERO but features a redesigned front panel that offers users a fresh visual experience. Thanks to the optimized DLP 3D-printed resin material, Truthear has succeeded in reducing the local material thickness inside the housing while maintaining impressive structural durability. Furthermore, Truthear has optimized the nozzle size and adjusted the support angles, thereby improving the overall comfort of the ZERO:BLUE2. The result is a lightweight and skin-friendly housing that is better suited for long-term use.‍Further-improved standard cableThe ZERO:BLUE2 features a 0.78 mm 2-pin design and comes with an improved, two-strand, high-quality, silver-plated copper coaxial cable. The number of internal strands has been further increased, which improves sound performance and provides a tangle-free experience.Technical SpecificationsName: TRUTHEAR ZERO:BLUE2Driver: 10 mm + 7.8 mm dynamic driverDiaphragm: Silicone suspension LCP liquid crystal + polyurethane suspension LCP liquid crystal composite diaphragmImpedance: 5.8 Ω ± 15% at 1 kHzSensitivity: 119.5 dB/Vrms at 1 kHzTHD: <1% at 1 kHzFrequency range: 20–41 kHz (IEC 61094, free field)Effective frequency range: 20–20 kHz (IEC 60318-4, -3 dB)‍Package contentsTRUTHEAR [ZERO:BLUE2] * 1Standard 3.5 mm cable * 1Ear tips * 3 pairs (S, M, L)Foam ear tips * 3 pairs (M)Foam ear tips * 1 pair (S)5-Ω impedance adapter * 1User manual * 1Warranty card * 1Anime card * 1

Dynamic in-ear headphones with two driversFeatures a dynamic driver design with a dual polyurethane suspension, a liquid crystal dome diaphragm, an N52 rubidium magnet, and an internal dual-chamber magnetic circuitFeatures a DLP 3D-printed chamber typically reserved for high-end products with multiple drivers and custom-fit earbudsEquipped with a silver-plated copper cable featuring thicker individual wiresDelivers outstanding objective measurement results‍Efficient, well-designed driver configurationZERO:RED features a configuration with two dynamic drivers, one with a diameter of 10 mm and the other 7.8 mm. The sophisticated internal magnetic circuit structure works in conjunction with a flexible polyurethane suspension combined with an LCP liquid crystal dome diaphragm. However, the internal configuration differs fundamentally from that of the standard ZERO, enabling RED to deliver superior objective performance metrics while meeting the demands of research and development.The same frequency-division concept is combined with a completely different dynamic driver to form a brand-new system. The 7.8-mm driver responsible for midrange and treble uses a specially tuned, ultra-fine CCAW voice coil that keeps the suspension system lightweight and ensures the resonance frequency is closer to the target curve, guaranteeing smoother reproduction. The 10-mm dynamic driver responsible for the bass precisely adjusts the number of voice coils to the requirements of the new crossover circuit; at the same time, the diaphragm structure is adapted, leading to a significant improvement in objective measurement values such as nonlinear distortion and better bass reproduction.‍Precise hybrid dual-frequency crossoverBased on high-precision DLP 3D printing technology, the acoustic nozzle structure with filter function and the precisely calculated RC crossover form a hybrid dual-frequency crossover that optimally highlights the capabilities of both dynamic drivers and brings the objective indicators closer to the design target.‍Outstanding objective indicatorsRED’s research and development goal is entirely new for TRUTHEAR: Building on the originally outstanding objective performance metrics of ZERO, RED’s nonlinear distortion has been further optimized at higher sound pressure levels (>94 dB), and the target frequency response curve exhibits amplitude characteristics in the bass range that resemble the public preference curve, while in the frequency band above 1000 Hz, the target curve of CRINACLE IEF_Neutral is adopted.These characteristics ensure powerful bass without compromising the sound of the higher frequency bands. Compared to ZERO, RED is relatively less dynamic but still aligns with HRTF characteristics, making RED very well-suited for long listening sessions without fatigue. Sonically, RED’s highs are bright without being harsh, delivering a warm, natural, and pleasant sound.‍Another important objective factor in multi-driver earphones is phase. The full-frequency phase of ZERO:RED is extremely consistent, and there are no convergence issues as found in conventional multi-driver earphones, thereby avoiding the unnatural listening experience caused by phase distortion.‍Next-generation DLP 3D printing technology and medical-grade resinThe DLP 3D-printed cavity mold manufactured by HeyGears, combined with medical-grade, highly transparent resin and an internal coloring process, ensures printing accuracy and efficiency. This achieves the delicate acoustic nozzle structure that is difficult to achieve with conventional methods, while also ensuring a lightweight cavity mold and skin-friendly, reliable materials.‍Optimized Manufacturing TechnologyTRUTHEAR not only strives for excellent objective measurement values but also places great emphasis on optimizing and improving manufacturing technology; the ZERO:RED housing half continues to feature a sandwich-like structure (front housing half, decorative bezel, and a few drops of adhesive to fill the joints). Through the use of 3D printing technology, the natural, gentle radius of the bezel is directly achieved, complemented by a few drops of adhesive to fill the joints. Combined with hand-polishing and automatic gloss coating, this results in an exquisite front bezel that ensures a durable and reliable structure.‍High-quality cable + flexible expandabilityFour strands of high-quality silver-plated cable, combined with the universal 0.78 mm 2-pin interface (the cavity is a recessed 0.78 mm 2-pin jack), ensure excellent sound quality and expand possibilities through cable replacement.Technical SpecificationsName: TRUTHEAR ZERO:REDDriver: 10 mm + 7.8 mm dynamic driverDiaphragm: Polyurethane suspension, LCP liquid crystal composite diaphragmImpedance: 17.5 Ω ±15% at 1 kHzSensitivity: 117.5 dB/Vrms at 1 kHzTHD: <1% at 1 kHzFrequency range: 20–40.5 kHz (IEC 61094, free field)Effective frequency range: 20–20 kHz (IEC 60318-4, -3 dB)‍Included ItemsTRUTHEAR [ZERO:RED] * 1Four-strand high-quality silver-plated cableEar tips * 3 pairs (S, M, L) (thick diameter)Ear tips * 3 pairs (S, M, L) (thin diameter)Foam ear tips * 1 pair (M)10-Ω impedance adapterUser manual * 1Warranty card * 1‍
