CVJ VVT-1: Wireless DAC and headphone amplifier with Bluetooth 5.3

The CVJ VVT-1 uses Qualcomm QCC5125 Bluetooth 5.3 chip + ESS 9039Q2M dual high power decoding chip. This combination delivers stable high-definition audio in a variety of modes, effectively reducing distortion and noise for clearer sound.


High standard headphone outputs on the two OPA2107s provide delicate and smooth sound quality. The TPA6120A2 custom amplification chip delivers approximately 800mW of power, keeping background noise low and inaudible even with highly sensitive headphones, resulting in clear sound quality.

Focus on sound. VVT-1 restores musical instruments and human voices, creating highly accurate and low-noise compositions. It achieves a smooth and dynamic sound, satisfying music lovers’ desire for distinct sound sources from musical instruments.


The built-in high-capacity lithium battery ensures a long service life: about 7 hours of battery life in standard conditions and about 7 days in standby mode. It supports power indication and charging during use. A flashing BTLINK light indicates the device is in standby state, while a solid green light indicates a successful connection.

Supports modern codecs, including LDAC, SBC, AAC, aptX, aptX-Adaptive, aptX-LL, aptX-HD, aptX-Adaptive, LHDC.
