VVT-1 Dual ES9039Q2M Bluetooth Decoding Portable Headphone Amplifier Wireless HiFi LDAC Lossless 4.4 Balanced Amplifier
Features:
- Using for Qualcomm QCC5125 Bluetooth 5.3 chip and dual decoding chip for ESS9039Q2M high-energy combination to achieve stable high-definition audio transmission in various modes, effectively reducing distortion and noise, and making the sound purer.
- Equipped with a large capacity lithium battery, it has a longer lifespan, with a continuous battery life of about 7 hours under standard conditions and a standby time of about 7 days. It supports battery level display and can be used while charging. When BT LINK flashes, it is in a standby state, and a constant green light indicates successful connection.
- Supports various high-definition Bluetooth audio protocols for LDAC, SBC, AAC, aptX, aptX Adaptive, aptX LL, aptX HD, aptX Adaptive, LHDC, etc.
- VVT-1 uses aluminum alloy as the shell material, tempered glass panel can reduce electromagnetic interference, and the shell anode can not only prevent aluminum alloy oxidation, but also reduce resistance.
- The high specification headphone amplifier output of the dual OPA2107 brings delicate and rich sound quality, and the TPA6120A2 dedicated amplifier chip brings about 800mW of high thrust, while the low noise floor is inaudible, even with high-sensitivity headphones, it can have clean sound quality.
- 3.5mm + 4.4mm dual ports, compatible with various types of headphones.
- The buttons support remote adjustment of up and down music and playback pause. Long pressing allows for volume adjustment, while holding down the up and down music buttons for 2 seconds can force the earbuds to not disconnect from the phone.

- The knob simulates the precise adjustment of volume through numerical control, effectively adapting to various high and low impedance and sensitivity headphones, effectively avoiding problems such as distortion. Turn on clockwise to turn on the device, increase the volume clockwise and press the pause button briefly to display the battery level.
