TRUTHEAR Zero Blue 2 are wired in-ear headphones for listeners who want dynamic, detailed, and balanced sound. Thanks to two dynamic drivers (10 mm + 7.8 mm), a redesigned acoustic design, and a detachable cable with a 0.78 mm 2-pin connector, they deliver clean detail, punchy bass, and comfort even during longer listening sessions.
Two dynamic drivers for balanced and detailed sound
The combination of a 10 mm driver for low frequencies and a 7.8 mm driver for mids and highs brings a wide range, clean detail reproduction, and better control across the entire spectrum.
Deeper bass with lower distortion
The redesigned 10 mm driver with bass-focused tuning provides greater depth and a more energetic character, while the construction helps reduce nonlinear distortion compared to the original Zero model.
Detachable cable and 0.78 mm 2-pin connector
The earphones use a 0.78 mm 2-pin connector, so the cable can be easily detached and replaced. The included cable is made of copper and silver-plated copper and is terminated with a 3.5 mm jack for broad compatibility.
The TRUTHEAR Zero Blue 2 model builds on the previous generations of the Zero series and brings redesigned acoustic chambers, output tubes, and key driver components. The goal is higher efficiency, lower distortion, and more natural reproduction across the entire range—from deep bass to delicate highs.
The pair of dynamic drivers has the frequency band split between them so that each operates where it is most efficient. The result is better sensitivity, consistent performance, and sound suitable for both everyday listening and more demanding use (for example, monitoring).
Main advantages:
- 2× dynamic driver: 10 mm for bass + 7.8 mm for mids and highs
