Features:
- Bluetooth independent decoding headphone amp
- Independent headphone amplifier, thrust guarantee. Different from the traditional integrated amplifier circuit, XP-2Pro adopts the new OP+BUF circuit architecture, with stronger driving ability, and the output power of the headphone amplifier is increased to 300mW
- 300mW high thrust: the output power reaches 300mW under 32Ω load, allowing earplugs/headphones to reach new heights
- AK4452 chip: DAC chip AK4452, excellent decoding performance, support native DSD, DXD and PCM signals, maximum support PCM--32BIT/384KHZ, DSD256, DXD 32BIT/352.8KHZ
- CSR8675 Bluetooth chip: support Bluetooth 5.0 version, and support for SBC, AAC, APTX, APTX LL, APTX HD, LDAC and other high-definition audio format transmission
- Call voice noise reduction: Built-in customized high-sensitivity audio microphone, support Bluetooth voice call, equipped with CVC8.0 voice noise reduction technology, the call is clearer, easy to chat (Attention: built-in microphone, only supports Bluetooth voice call mode, not for mobile phone voice assistant dialogue, WeChat voice, QQ voice)
- One touch to connect: With NFC function. One touch with NFC-enabled devices, you can identify and connect easily, no longer bother with cumbersome settings
- Asynchronous USB DAC: It can be used as an external USB DAC. The USB receiving chip adopts the new XU208 for XMOS, working in asynchronous transmission mode, PCM supports up to 32bit/384kHz, DXD 32bit/352.8kHz; DSD supports DOP, NATIVE mode, DSD maximum Support DSD256, support for iPhone/IOS devices, Android system phones, player audio decoding and the like (Attention: need to use an official original camera data cable for Apple to connect)
- RGB indicator light: The change of each color represents a different encoding format. In Bluetooth pairing mode: SBC: blue light is on; AAC: cyan light is on; for LDAC: white light is on; for aptX/aptX LL/aptX HD: Purple light is on(Attention: 1. When the battery level is less than 20%, the orange light is always on; 2. In the off-charging mode, the red light is always on, and the green light is on when fully charged)
- Long Endurance Time: Endurance time: USB IN≥8H; AUX IN≥22H; Bluetooth≥15H. Charging time: ≤3 hours
- Process breakthrough: The shell is made of high-strength aluminum alloy, with high-hardness 2.5D tempered glass process on the front and back, and the red volume knob is matched with the space gray body
