High-Definition Bluetooth Audio Transmission

Through the magic of Bluetooth 5.0, the XP-2 is able to deliver detailed, hi-res audio, even without wires at play. It’s not all thanks to the Bluetooth chip itself, but the powerful DAC chip that decodes at professional levels.

A PC USB DAC that Carries its Weight

The xDuoo XP-2 is a professional DAC, make no mistake. Using the SA9123 chip which supports asynchronous USB data transmission, you’re able to enjoy music with qualities of up to 24-bit at 192kHz in the PCM format, which is guaranteed to sound fantastic.

A High-End DAC for Your Smartphone

Whether you have an Apple or Android device, the XP-2 can breathe new energy into your audio experience. Even on mobile, it is able to support PCM audio as high as 24-bit 192kHz, though an Apple Camera Connection Kit is needed for iOS and an OTG adapter for Android.

Two Gain Adjustment Levels

The XP-2 gives you full control over gain adjustment, allowing you to set it between coarse and fine gain, which makes it perfectly versatile for use with headphones with different sensitivities.

An Intimidating Amp Circuit

The amp circuit here makes use of the OP+BUF architecture. The power supply delivers +/- 5V of electricity through a highly efficient conversion mechanism, with an OCL circuit structure employed. This structure and these components coalesce to deliver extremely powerful sound with clean, balanced bass.
