Convenient to Carry

Whether you’re at home, in the office, on a business trip, or traveling, the XD05 BASIC2 is extremely portable. Its compact design lets you enjoy high-quality music anywhere and anytime.

Powerful Decoding Ability

This device functions as a USB DAC, making it easy to connect to computers, smartphones, tablets, and portable music players via USB. It supports high-definition formats—including PCM 32-bit/384 kHz, DSD256, and MQA (8× unfolding)—allowing you to hear subtle instrumental details often lost in standard formats.

LE Audio Bluetooth 5.4

Featuring the latest Bluetooth 5.4 technology, this model offers faster transmission speeds and supports the new LE Audio codecs for lower latency and improved sound quality. It is backward-compatible with traditional Bluetooth codecs and handles high-definition formats such as aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC.

Powerful Driving Ability

The headphone jack delivers up to 750 mW per channel. With selectable high and low gain settings, it can drive a wide variety of headphones—ensuring clarity and power even with demanding loads.

Excellent Parameters

With a THD of just 0.0006 %, the XD05 BASIC2 preserves the audio signal’s original tone during amplification, minimizing distortion and noise. Its 124 dBA SNR guarantees low background noise, so you can discern musical nuances more clearly.

Freely Switch Between Portable & Desktop Mode

Choose between battery power for on-the-go listening or DC power for stationary use. Desktop (DC) mode boosts driving force while reducing battery strain, effectively prolonging playback time when you’re not moving around.

EQ Adjustment

If you want more impactful bass while watching a movie, simply enable the bass boost option in the menu. This lets you experience deep, thumping lows and explosive sound effects at the touch of a button.

Digital Volume Adjustment

Modern Hi-Fi headphones demand precise volume control. The XD05 BASIC2 uses digital volume steps—eliminating left/right imbalance at low volumes inherent in traditional potentiometers. With 99 fine-grained levels, you can find the perfect setting for any headphone impedance or sensitivity.

Simple to Change Amplifier Chip

For those who like to customize their sound, the operational amplifier (op-amp) chip is user-replaceable—no specialized tools required. Swap chips by hand to explore different tonal characteristics and tailor your listening experience.

Carefully Selected Materials

Every component that affects sound quality has been selected and tested rigorously. The unit employs a professional-grade CS43131 DAC chip, chosen for its low THD, high SNR, and exceptional resolution, ensuring the best possible audio performance.
