TRUTHEAR X CRINACLE ZERO:BLUE2 In-Ear Monitors

The Truthear x Crinacle ZERO:BLUE2 in-ear monitors push the boundaries of audio performance at an affordable price, thanks to an innovative dual internal cavity design and two optimized dynamic drivers. The first, 10mm, uses a composite LCP membrane with silicone suspension and a powerful N52 magnet for deep, punchy bass. The second, 7.8mm, shares a similar membrane and suspension, but benefits from an N55 magnet and a redesigned structure to excel in the midrange and high frequencies.

The ZERO:BLUE2 benefit from a high-precision DLP-3D printing process for their internal cavities, a technique usually reserved for high-end multi-driver headphones. They come with a new cable with silver-plated copper conductors for optimum signal transmission, and a second cable with microphone for calls.

Truthear x Crinacle ZERO:BLUE2: Improved design

Like their predecessors, the ZERO:BLUE2 incorporate a dynamic double-driver configuration. However, the 7.8mm driver has undergone a significant redesign, with an optimized magnetic circuit, flexible polyurethane suspension and LCP diaphragm, all targeting superior midrange and high-frequency reproduction. The driver's magnet has been increased in diameter by around 25% and in diaphragm area by almost 50%, considerably improving response and high-frequency efficiency.

The 10mm driver, dedicated to bass, has also been optimized with a new silicone suspension perfectly matched to its LCP diaphragm and an ultra-fine wire coil for precise, controlled bass. This design uses a low-distortion crossover similar to that of the ZERO:RED, resulting in improved metering and reduced non-linear distortion for deep, impactful bass.

Truthear x Crinacle ZERO:BLUE2: Hybrid crossover

The internal structure of the acoustic chambers has been completely redesigned, and a low-distortion crossover circuit has been integrated to optimize the overall sound experience. This new design aims to improve the efficiency of each driver in its dedicated frequency band, ensuring a smooth transition and remarkable sonic coherence.

Truthear x Crinacle ZERO:BLUE2: Excellent measurements

Truthear's teams have meticulously worked on the ZERO:BLUE2 to achieve high efficiency and extremely low linear and non-linear distortion. In terms of non-linear distortion, the ZERO:BLUE2 outperforms even the ZERO:RED in certain frequency ranges, offering minimal background noise and a sound rich in detail. For linear distortion, the targeted frequency response curve has been precisely calibrated to align with audiophile preferences, with optimization of very low frequencies (below 50Hz) and high-frequency response following the characteristics of the HRTF (Head-Related Transfer Function) curve. These optimizations combined enable the ZERO:BLUE2 to deliver dynamic, lively and nuanced sound reproduction.

Truthear x Crinacle ZERO:BLUE2: A precision-printed shell

The shells of the Truthear ZERO:BLUE2 earphones benefit from the precision of 3D-DLP printing provided by their partner HeyGears. The resin used results in lightweight, durable earphones offering optimum wearing comfort. The size of the acoustic tube has also been adjusted to improve ergonomics.

Truthear x Crinacle ZERO:BLUE2: High-quality cable and microphone

Truthear ZERO:BLUE2 in-ear earphones feature a 2-pin 0.78mm CIEM connector, ensuring a secure connection and the possibility of using third-party cables. They come with a main cable using silver-plated copper conductors for perfect signal transmission. In addition, a second cable with OFC copper conductors and an integrated microphone is included, offering a practical solution for easy call answering.
