Building on the success of the highly regarded Xduoo XD-05—a DAC/amp that changed the game with its versatile desktop-to-pocket portability—the Xduoo XD-05 Plus keeps old favorites while adding a host of new features. New on the XD-05 Plus are an AK4493EQ DAC and XMOS XU208 USB chipset to improve sound quality, as well as onboard USB-C ports to update connectivity. Another new feature is the lithium 5000mAH battery, which is capable of 13 hours of playback via USB, 21 hours via SPDIF, and 40 via aux in. Also upgraded is the power output: The XD-05 plus boasts an impressive 1000 mW at 32 ohms—ideal for even the most demanding headphones. Like its predecessor, the XD-05 Plus allows you to change out op amps without soldering to suit your listening preferences. Add the optional XD-05BL Pro to bring Bluetooth 5.0 functionality with a 10-meter range to the XD-05 Plus.

Designed as an add-on for Xduoo XD-05 Plus, the XD-05BL Pro delivers expanded connectivity capabilities for those who want to listen wirelessly, charge faster, and talk with an onboard microphone. An improvement on the XD-05BL, the Pro features an upgraded CSR8675 Bluetooth chip, adding support for SBC, AAC, aptX, aptX Low Latency, aptX HD, and LDAC formats. It also adds CVC noise-cancelling on its microphone and  USB-C charging for more efficiency.
