#4 Fosi Audio DS3: $99.99 Amazon eBay

Pros: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. A 32-band parametric EQ gives unusually fine tuning control for a dongle, and it offers both 3.5 mm and 4.4 mm balanced outputs. At 16 g and 55 mm long, it is very light to carry.

Cons: Its rated 220 mW into 32 ohms drives most headphones but leaves less headroom than the FiiO KA15, which costs the same and rates higher. The TRN Black Pearl also rates higher and measures slightly cleaner for much less. Volume is button controlled.
