Why pick the E1DA 9039S: Audio Science Review measured a SINAD of 125 dB, so its noise and distortion are inaudible, even with sensitive in-ears. Watch for: Its only headphone output is a 2.5 mm balanced jack, so most headphones need an adapter or a new cable.

Pros: Audio Science Review measured a SINAD of 125 dB, so its noise and distortion are inaudible, even with sensitive in-ears. E1DA rates it at 400 mW into 32 ohms balanced, enough for most headphones from a 10 g USB-C dongle with dual ES9039Q2M chips.
Cons: Its only headphone output is a 2.5 mm balanced jack, so most headphones need an adapter or a new cable. The FiiO KA15 rates higher with more balanced power for less.

TempoTec Sonata BHD Pro: $69.90 Amazon eBay
Pros: Audio Science Review measured a SINAD of 112 dB, clean for nearly all listening. A rated 280 mW into 32 ohms from the 4.4 mm balanced output drives most headphones, and a 3.5 mm output is also included. At 18 g it is easy to keep attached to a phone, and it costs less than the Fosi Audio DS3.
Cons: Its SINAD is lower than most rivals here, and the TRN Black Pearl rates higher with 117 dB and more rated power for less. There is no EQ listed and volume is button controlled. The rated power figure applies to the balanced output only.
