The Shanling UA4 is a 20.8 g USB DAC/amp dongle with an ESS ES9069Q chip, a 0.87-inch OLED screen and 3.5mm plus 4.4mm balanced outputs, the balanced jack rated at 227 mW into 32Ω. It suits IEM and easy-headphone listeners who want a light, screen-equipped stick for a phone or laptop.
Who the Shanling UA4 is for
IEM listeners on a phone: Shanling notes that it draws only a small amount of power from the connected device, so it is easy on a phone battery.
Balanced-terminated IEMs: The 4.4mm jack is rated at 2.7 V / 227 mW into 32Ω versus 2.1 V / 137 mW from the 3.5mm, so a balanced cable gets the most from it.
Fans of on-device controls: The 0.87-inch OLED shows sample rate, gain and filter, and three buttons handle volume and playback without needing an app.
Nintendo Switch and older devices: Holding the multifunction button while plugging in switches it to UAC 1.0 mode, which Shanling provides for the Switch, other consoles and older Android devices.
Skip it if: you need real power for hungry planars or 300Ω headphones; it is rated at 227 mW into 32Ω balanced and is aimed at IEMs and easier headphones.
