Description：  

     - Professional power amplifier circuit, powerful output power  

     Different from the traditional integrated amplifying circuit, XP-2Pro applies the brand-new OP+BUF circuit structure, bring more thrust. The amplifier output power is enhanced to 300mW!  

     - 300mW output power  

     Under the 32ohm load, output power is up to 300mW, solve that your headphones can’t be drive well enough, so as to drive your headphone to a new level.  

     - AK4452 chip  

     DAC chip adopts AKM’s AK4452 chip, shows the excellent performance, and supports native DSD, DXD and PCM signals. The maximum support is PCM-32Bit/384kHz, DSD256, and DXD 32Bit/352.8kHz.  

     - Qualcomm’s Bluetooth chip CSR8675  

     With Qualcomm’s flagship Bluetooth chip CSR8675, it supports Bluetooth 5.0 version and supports SBC, AAC, APTX, APTX LL, APTX HD and LDAC high-definition audio format transmission.  

     - Built-in microphone with Qualcomm cVc noise cancellation technology  

     The built-in customized audio microphone with high sensitivity supports Bluetooth voice communication. Matching with the new generation of Qualcomm’s cVc8.0 noise reduction technology, it is clearer in communication to chat like a cork and you won’t pull out the mobile in a hurry to feel awkward.  

     *Note: the built-in microphone is only available under the Bluetooth voice communication, instead of mobile voice assistant.  

     -Simple one-touch NFC pairing  

     With NFC function, after it contacts the equipment with NFC function, it can recognize and easily link with it. You won’t be bothered by fussy setting.  

     -Asynchronous USB DAC  

     It can be used as the external USB DAC. USB receiver chip applies XMOS’s XU208. With asynchronous transfer mode, maximum support of PCM is up to 32Bit/384kHz, DXD 32Bit/352.8kHz; DSD256. Also, it supports iPhone/iOS equipment, Android phone, and player audio decoding…  

     *Note: it needs Apple’s official original camera USB.  

      Multi-color indicator  

     Change of each color represents different coding formats.   

     Under the Bluetooth mode:  

     SBC: blue light  

     AAC: green light  

     LDAC: white light  

     aptX/aptX LL/aptx HD: purple light  

     *Notes: 1. When the battery power is less than 20%, the orange lamp is always on;  

                  2. Under the charging mode, the red light is always on; after it is fully charged, the green light is always on.  

     - Battery life  

     Battery life: USB IN≥8H, AUX IN≥22H, Bluetooth≥15H  

     Charging time: ≤3H  

     - New appearance technology  

     Adopts high-strength aluminum alloy. Matched with high-hard 2.5D tempered glass technology, and the red volume button is matched with deep grey body to show personality in calmness.
