You are likely familiar with the TRUTHEAR x Crinacle ZERO, which has become one of the most popular in-ear monitors since its release. Today, TRUTHEAR makes an impressive leap forward by collaborating with Crinacle to introduce the remarkable successor to ZERO:BLUE2! Let’s take a look at the improvements it brings to the table!
Like its predecessors in the ZERO series, the ZERO:BLUE2 features dual dynamic drivers. However, the structure of the 7.8mm dynamic driver has been modified, focusing on mid and high frequencies. This driver utilizes a mature internal magnetic circuit structure, incorporating flexible polyurethane material for suspension and an LCP dome diaphragm. Despite these similarities, the internal design is quite different from earlier models.
TRUTHEAR has achieved a significant breakthrough by increasing the diameter of the magnet for the 7.8mm driver by approximately 25%. Additionally, they expanded the dome area by about 50% and improved the high-frequency conductive structure. Although these changes make the production and processing of this dynamic driver more challenging, they enhance conversion efficiency and greatly improve sensitivity in the upper high frequencies. This advancement not only meets our R&D needs but also results in objectively superior measurements, yielding a smooth, transparent high-frequency response with enhanced extension and excellent resolution.
Furthermore, the 10mm dynamic driver, which handles the bass frequencies, has also received an upgrade. The newly adjusted solid silicone suspension aligns with the liquid crystal dome diaphragm and features an ultra-thin wire diameter voice coil, creating a brand-new bass tuning system. This system employs a low-distortion frequency crossover design similar to that of the ZERO: RED, resulting in significantly improved objective measurements, such as lower nonlinear distortion compared to the original ZERO. As a result, users can expect deeper and punchier bass performance.
Truthear has redesigned the cavity structure and low-distortion frequency crossover circuit based on valuable experience and user feedback from previous models featuring double dynamic drivers. This redesign aims to enhance the dynamic drivers' conversion efficiency while allowing each speaker to fulfill its respective role. As a result, the sensitivity significantly improved. The filtered nozzle, accurately printed by HeyGears using high-precision 3D-DLP technology, works in conjunction with a mixed multiple frequency crossover, bringing the objective measurements of the ZERO:BLUE2 closer to the intended design goals.
The R&D goal of ZERO:BLUE2 marks a departure from previous TRUTHEAR products. The aim is to enhance overall conversion efficiency while maintaining excellent performance in both linear and nonlinear distortion.
Non-linear distortion: ZERO:BLUE2 not only meets our anticipated R&D objectives but also outperforms RED in certain frequency ranges regarding non-linear distortion. It delivers a clean background and effectively restores details, allowing for accurate reproduction of musical timbre.
Linear distortion: The frequency response curve targeted by ZERO:BLUE2 is designed to align more closely with public preference characteristics. We have optimized the low bass response (below 50Hz) through various means, ensuring a smoother transition in the mid frequency. The high frequency are closely matched to the amplitude response characteristics of HRTF, maintaining high sensitivity above 10000Hz.
These enhancements have significantly optimized ZERO:BLUE2 compared to the performance metrics of ZERO. In terms of subjective listening experience, it offers a more dynamic and vivid sound than RED, with excellent high-frequency conversion efficiency that reveals the subtle details in recording and mixing processes.
Additionally, ZERO:BLUE2 features highly consistent full-band phase characteristics, effectively eliminating the unnatural listening experience often caused by phase distortion.
The ZERO:BLUE2 incorporates a 0.78mm 2-pin design and comes with an upgraded two-strand high-quality copper and silver-plated coaxial cable. The number of internal wires has been increased further, enhancing sound performance and providing a tangle-free experience.
Moreover, it offers a microphone option that includes not only the two-strand high-quality copper and silver-plated coaxial cable with a 3.5mm single-ended 0.78mm 2-pin connection, but also features an oxygen-free copper mic cable of exceptional quality (same as the mic cable used in the GATE). This makes the ZERO:BLUE2 not just an excellent companion for music and monitoring but also a reliable assistant for calls and gaming.
