Decision Profile · L2 · documentation + editorial inference

A USB-C bus-powered dongle DAC with balanced 4.4 mm and single-ended 3.5 mm headphone outputs.

Evidence checked / updated: 2026-10-11. Manufacturer claims and editorial system-fit assessment. No SoundPath Lab listening or measurement test.

Verified documentation

  • Host input: USB-C audio; PCM384 and DSD256, subject to the host and playback app.
  • Manufacturer RMS power: 4.4 mm: 241 mW/32 ohms; 3.5 mm: 100 mW/32 ohms. Different outputs are not interchangeable wiring.
  • Load and portability: 14.5 g; no internal battery. Maximum listed consumption 3.2 W is drawn from the USB host.

Best for

minimal-size wired phone or laptop headphone playback

Avoid if

You need wireless playback, its own battery, analogue input, or substantial desktop headphone power.

Limits and unknowns

USB power affects the phone battery; adapter, OS and app behavior need verification. Use correctly terminated headphone cables rather than shorting a balanced output into a single-ended plug.

Current verdict

Conditional shortlist for minimal-size wired phone or laptop headphone playback. The recommendation depends on the documented system conditions, not an independent sound-quality ranking.

Why it fits

A USB-C bus-powered dongle DAC with balanced 4.4 mm and single-ended 3.5 mm headphone outputs. This assessment is an editorial inference from the documented topology.

What it can replace

Can consolidate the functions stated in the profile when the source, load and control path meet the conditions below. The useful replacement is a function or connection gap, rather than an assumed improvement in sound.

What it cannot replace

You need wireless playback, its own battery, analogue input, or substantial desktop headphone power.

What SoundPath Lab tested

SoundPath Lab checked primary-source model identity, the stated interfaces and conditions, and this decision profile. No device was listened to, measured, installed, firmware-retested or endurance-tested for this review.

What remains untested

Actual sound preference, noise with your headphones or speakers, software behavior, room results, connection stability and long-term reliability remain untested. Manufacturer measurements below are not SPL measurements.

System conditions

The phone must support USB audio and sufficient power; Lightning needs the appropriate Apple-compatible audio path. Choose 3.5 or 4.4 mm for the actual headphone cable.

Alternatives by need

hip-dac 3 provides its own battery and more physical controls; ZEN DAC 3 suits a fixed USB desktop with line outputs.

Keep or upgrade

Keep a working system if it already provides the connections and level you need. Consider this model only if its documented role solves the specific need described above; check the alternatives and all remaining costs before changing equipment.

When to reassess

Reassess after a material manual or firmware change, an independently reproduced issue, a hardware revision, or a documented change in service or repair availability. A routine update does not prove that an existing issue is resolved.

Ownership evidence

No six-month ownership study was performed. Battery wear, pad or stylus replacement, service dependence and local repair access should be evaluated for the actual use case. No future reliability outcome is predicted.

Firmware, manual and support

The linked official model manual was read for connection and operation conditions. Follow the manual matching your hardware and market. Current firmware, app compatibility and the long-term repair horizon remain unverified unless separately stated.

Launch day, globally uniform price, local authorized stock, repair turnaround and guaranteed support end date were not established in this review. Regional store offers are not global availability. No defect-free or six-month reliability claim is made.

Revision record

2026-10-11 — Promoted from L1 to L2 after full Decision Profile review. Stable product identity retained; source conflicts and untested behavior remain visible. L2 is evidence coverage, not independent test acceptance or automatic recommendation.
