Short answer: the Fosi Audio DS2. It ranks #7 of 14 usb-c dongle DACs by measured performance, rated 4.1/5, at $59.99; the Rode AI-Micro ranks #13, rated 2.1/5, and costs $79, which makes this an easy call rather than a real tradeoff.
The Fosi Audio DS2 is the better-sounding choice. Audio Science Review measured 117 dB SINAD, so its noise and distortion are transparent. The tradeoff: A rated 170 mW into 32 ohms, and only from the balanced output, drives most headphones but leaves little headroom for planar magnetics.
The case for the Rode AI-Micro: It doubles as a small audio interface, with two 3.5 mm microphone inputs alongside its headphone jack, and weighs just 0 lbs (13 g). The tradeoff: Audio Science Review measured only 80 dB SINAD, a level where noise and distortion can be audible, especially with sensitive in ear monitors.
Buy the Fosi Audio DS2. It is rated higher than the Rode AI-Micro and costs less, so only choose the other one for a particular feature it does better.

The Two Amps and DACs In Full
Fosi Audio DS2: $59.99 Amazon eBay
Pros: Audio Science Review measured 117 dB SINAD, so its noise and distortion are transparent. It offers both a 3.5 mm jack and a 4.4 mm balanced output, with physical volume buttons, from a USB-C dongle. It rates higher than the FiiO KA11 and JCALLY JM20MAX.
Cons: A rated 170 mW into 32 ohms, and only from the balanced output, drives most headphones but leaves little headroom for planar magnetics. The TRN Black Pearl rates higher with more balanced power and the same SINAD for less, and at 91 g it is heavy for a dongle.

Rode AI-Micro: $79.00 B&H Photo eBay
Pros: It doubles as a small audio interface, with two 3.5 mm microphone inputs alongside its headphone jack, and weighs just 13 g. A rated 125 mW into 32 ohms drives most headphones. It rates higher than the Periodic Audio Rhodium.
Cons: Audio Science Review measured only 80 dB SINAD, a level where noise and distortion can be audible, especially with sensitive in ear monitors. There is no balanced output. The FiiO KA11 rates far higher with much cleaner measurements for less.
