Shanling has long had a knack for making small audio gear feel genuinely premium, and the UA1 II shows just how far the modern USB dongle has evolved. This isn’t a light refresh or a cosmetic tweak. The UA1 II feels like a proper step forward, blurring the line between entry-level dongles and full-featured portable DACs from just a few years ago.

Despite its extremely compact footprint, the UA1 II immediately feels like a mature product. Weighing just under 18 grams and small enough to disappear into a pocket, it still manages to look and feel intentional rather than disposable. The updated aluminum body is slim and smooth, with softly rounded edges that sit naturally next to a smartphone, tablet, or laptop. Two glass windows add a touch of flair, one on the front housing a small color display, and another on the rear revealing a glimpse of the internal layout. It’s subtle, but it gives the UA1 II a sense of identity that many dongles lack.

The Shanling UA1 II is a case where a compact dongle is no longer “just a Hi-Fi input.” Balanced output, dual DACs, a screen, hardware controls, and serious power make it a versatile solution for both everyday listening and gaming.

What really sets the UA1 II apart, though, is that it doesn’t rely on an app or a phone screen for control. A set of physical buttons is neatly integrated into the chassis, allowing full standalone operation. Volume, playback, and menu navigation are all handled directly on the device, and the screen lets you dive into settings such as digital filters, gain level, channel balance, and real-time playback information. Once configured, everything is stored in the DAC’s internal memory, so your preferences stay exactly where you left them, even when switching between devices.

Inside, Shanling has gone with a dual Cirrus Logic CS43131 DAC configuration. This isn’t done for marketing flash; it’s a proven chip known for a clean, musical presentation and excellent efficiency in portable designs. The UA1 II supports high-resolution PCM up to 32-bit / 768 kHz and native DSD512, figures that would have seemed excessive for a dongle not that long ago. In practice, it means the UA1 II never feels like a bottleneck, even with high-resolution files and demanding playback software.

The device is compatible with Android , Windows (drivers required), and iOS via a separate Shanling Lightning cable. The Eddict Player app is also supported , although all basic features are available without it.

Power delivery is another area where this tiny DAC punches well above its weight. With both single-ended and balanced headphone outputs on board, the UA1 II is the most powerful model in the UA1 lineup to date. Through the balanced 4.4 mm output, it delivers enough current to comfortably drive many full-size headphones, while remaining dead-quiet with sensitive in-ear monitors. The low output impedance and strong measured performance translate into a confident, controlled sound that feels stable regardless of what you plug into it.

In real-world listening, the UA1 II comes across as clean, fast, and well balanced. There’s no artificial sharpness or exaggerated edge, but plenty of clarity and dynamic snap. Bass stays tight, transients are quick, and the noise floor is impressively low. It’s a tuning that works equally well with modern electronic music, rock, and jazz, and the balanced output in particular gives the sound a little extra headroom and authority.

Inside are two Cirrus Logic CS43131 - popular Hi-Fi DACs, known for their clean, dynamic and at the same time musical character.

One of the more practical touches is the inclusion of a UAC 1.0 mode, which makes the UA1 II compatible with devices that don’t normally play well with modern USB DACs. That includes gaming consoles like the Nintendo Switch and other systems where low latency and plug-and-play operation matter. For anyone who games with headphones and wants better sound without added complexity, this feature alone makes the UA1 II more versatile than most dongles in its class.

Connectivity is straightforward and well thought out. The UA1 II uses USB-C and ships with a high-quality USB-C to USB-C cable, a USB-A adapter, and the necessary documentation. It works seamlessly with Android devices, Windows systems with drivers installed, and iOS when paired with Shanling’s Lightning cable. While the Eddict Player app is supported, it’s entirely optional, as all core functions are accessible directly from the device itself.

With a weight of about 17.5 g and dimensions of 52 × 22 × 13 mm, the UA1 II easily fits in a pocket, but it is not lost in its capabilities.

Taken as a whole, the Shanling UA1 II feels like a statement about where compact hi-fi is heading. This is no longer just a “better headphone jack.” With balanced output, dual DACs, a built-in screen, physical controls, and enough power for serious headphones, it’s a genuinely capable all-rounder for everyday listening, travel, and even gaming.

 The UA1 II is a prime example of how the input dongle has grown into something much more mature.
