Features
  • With Bluetooth and USB input, perfectly compatible with mobile phone, computers, and with stereo L/R RCA / 3.5mm AUX outputs, can connect preamps, amplifiers, active speakers. It's also with a wide range of adaptability, brings obvious improvement in sound quality when used in the car and avoids the trouble of inserting U-disk or CD.
  • Adopting CSR8675 Bluetooth chip supporting LDAC and APTX-HD transmission, always working in 192KHz/24bit decoding mode to provide HiFi lossless music. And USB input supports computer and phone with OTG function(Android system needs OTG cable and OS system needs large current camera kit), no need for any driver, plug and play, very convenient.
  • Adopting independent CS4398 decoding chip and JRC4580 op amp working in ±15V, full of analog style and very listenable. And built-in frequency up ciruict is designed to fix sampling rate at 24bit/192Khz because CS4398 chip must be at 24bit to reach its perfect performance.
  • Mini size and cool appearance, with volume control and songs selection, easy to use. Mirco-USB interface can power and do data transmission at the same time, DC 5V working voltage, can be powered by phone charger or power bank when using Bluetooth input, can enjoy HiFi music any time and any where.

Warm tips:
 
1. Bluetooth input with priority, USB input will auto quit when Bluetooth is connected. 3.5mm AUX is LINE OUTPUT, cannot provide good performance if connect headphones directly.
2. USB sound card input supports 48K/16bit, the computer display supports up to 48KHz, while with built-in frequency up circuit so the CS4398 chip is still decoded at 192K/24bit.
3. Recommend to use mobile phones that support APTX-HD or LDAC function to play lossless music, the sound quality is very close to CD players.
