TRUTHEAR Zero Blue 2 Wired Headphones (Blue)

TRUTHEAR Zero Blue was created for listeners who expect dynamic, detailed sound and well-controlled bandwidth across the entire frequency range. The design uses two dynamic transducers with a diameter of 10 mm and 7,8 mm, an extensive frequency division system and solutions developed on the basis of experience gained with previous Zero series models. Acoustic chambers, nozzle and a number of elements of the transducers themselves were also redesigned, focusing on higher efficiency, reduced distortion and more natural reproduction of recordings. The whole is complemented by housings made by 3D-DLP printing by HeyGears and a detachable copper and silver-plated copper cable. Thanks to this, the design is prepared both for listening to music and for more demanding listening, monitoring, and in the variant with a microphone also for talking and playing (cable with a microphone available outside the set).

Two dynamic transducers

The reproduction of medium and high frequencies is due to a redesigned 7,8 mm dynamic transducer with an internal magnetic system. It uses a flexible suspension made of polyurethane and a dome membrane made of LCP, i.e. liquid crystal polymer. Compared with the older model, the diameter of the magnet was increased by about 25%, while the dome area increased by about 50%. The conductive structure in the high frequency range has also been modified. These changes allowed to increase the efficiency of the transducer and its sensitivity in the highest part of the band, ensuring smooth, transparent presentation of high tones, better bandwidth extension and high resolution.

Stronger bass base

The lower frequencies were entrusted to a dynamic transducer with a diameter of 10 mm, which was also modified. It uses a properly tuned suspension made of solid silicone, a membrane with a dome made of liquid crystal polymer and a vibrating coil using a thin wire. In this way, a changed bass tuning system was created, cooperating with a frequency division system with a low level of distortion, similar to the solution used in the Zero Red series. Thanks to this, it was possible to achieve lower non-linear distortion than in the original Zero model, and the bass gained more depth and a clearer, more energetic character.

Precise bandwidth division

The design of the acoustic chamber and the crossover system have been redesigned on the basis of experience with previous TRUTHEAR headphones using two dynamic drivers. The aim is to increase the efficiency of both transducers and at the same time enable each of them to work in a properly selected frequency range. As a result, the sensitivity of the entire system was significantly improved. An important role is also played by the filtered nozzle precisely made by HeyGears in 3D-DLP technology, which works with a hybrid, multi-stage bandwidth division system. The design developed in this way allows you to better approximate the parameters of the headphones to the assumptions adopted at the design stage.

Cleanliness and more details

During the development of the Zero Blue 2, particular emphasis was placed on increasing overall efficiency while maintaining very good linear and nonlinear distortion parameters. In selected frequency ranges, the level of nonlinear distortion is lower than in the Zero Red series, which promotes maintaining a clean background and clear reproduction of small details. The frequency characteristics have been tuned to better suit a wide listening preference, with an optimized response of the lowest bass below 50 Hz and a smoother midrange transition. High frequencies were adjusted to the amplitude characteristics of HRTF, while maintaining high sensitivity also above 10 000 Hz.

Vivid and consistent sound

Compared to the first Zero model, a number of changes have been introduced affecting both the measurement results and the nature of the listening session. Zero Blue 2 offers a more dynamic and vibrant sound than Zero Red, and the high efficiency of the transducer responsible for the upper band allows you to bring out the subtle elements present in recordings and mixes. The headphones are also distinguished by very consistent phase characteristics throughout the band. Reducing problems associated with phase distortion helps maintain a more natural sound reception, and an increased number of internal conductors favorably affects sound properties.

3D Printed Enclosures

HeyGears is again responsible for the construction of the enclosures, using precise 3D-DLP printing technology. Zero Blue 2 retain stylistic references to the first Zero, but received a redesigned external panel. The optimized resin used in printing allowed to locally reduce the thickness of the material inside the chamber without sacrificing the appropriate strength of the structure. The nozzle size and support angles have also been changed, paying special attention to comfort during extended use. The enclosures are skin-friendly and have been prepared for hours of listening sessions.

Improved cable

Zero Blue 2 use a 0,78 mm 2-pin connector, which allows you to disconnect and replace the cable. The set uses an improved, two-core coaxial cable made of high-quality copper and silver-plated copper, and an increased number of internal conductors are designed to support transmission properties. The cable's design is also designed to reduce tangling during daily use. There is also a variant with a microphone, including a cable terminated with a 3,5 mm plug and 0,78 mm 2-pin connectors, and a high-quality microphone cable made of oxygen-free copper, the same as used in the TRUTHEAR Gate model (not included).
