#7 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.
