A DAC/Amp the size of your key fob

The xDuoo Link10 is a compact USB DAC and headphone amplifier designed for everyday carrying. Despite its size—it’s smaller than most key fobs—it packs dual Cirrus Logic CS43131 DAC chips, balanced and unbalanced outputs, 300mW of output power at 32Ω, and bit-perfect decoding up to PCM 32-bit/384kHz and native DSD256. It's battery-free and designed to plug straight into phones, tablets, laptops, or gaming consoles. 

Phone, tablet, laptop, Switch, and Playstation ready

The Link10 was built to be a universal tool. Plug it into your phone, tablet, laptop, or even your Nintendo Switch or PlayStation. It supports both USB Audio Class 1.0 and 2.0—meaning it can handle high-res audio streams from music apps and also work natively with most game consoles without having to download drivers.

High output power, low impedance 

Need to drive power-hungry headphones? No problem. The Link10 delivers up to 300mW into 32Ω and 270mW into 150Ω. That’s enough to run a wide range of dynamic and planar headphones without additional amplification. 

Dual DACs

The Link10 uses two CS43131 DAC chips—one per channel—for true balanced decoding. These chips are known for high efficiency, low noise, and detailed, uncolored sound. You get an SNR up to 130dB and a THD+N as low as -115dB, which means cleaner signal, blacker background, and sharper instrument separation.

Digital volume with 60-step precision

Whether you’re using sensitive IEMs or full-sized headphones, the Link10 gives you volume control across 60 digital steps. The digital volume circuit adapts well to any impedance and lets you fine-tune levels with minimal channel imbalance.

Game mode built in

Want better audio in handheld mode on the Switch or clearer team chat on your PlayStation? Just switch to UAC1.0 mode before plugging in. It’s easy: press and hold the volume button before connecting to enter the correct mode.
