Short answer: the Moondrop Ultrasonic. It ranks #103 of 1291 in-ear headphones by sound quality, rated 4.5/5, at $89.99; the Simgot EA500 DSP ranks #180, rated 4.4/5, and costs $90.99, so there is little reason to consider the other one.
Why pick the Moondrop Ultrasonic: It is a true wireless earbud with active noise cancelling, LDAC and LC3 support over Bluetooth 5.3, and 6 hours of playback with 24 in total from the case. Watch for: Sub-bass falls about 2.9 dB below target and 3.4 dB down at 30 Hz, so deep bass lacks the slam many wireless buyers expect.
The case for the Simgot EA500 DSP: Hobbyist measurements give it a Harman preference score of 78.3 with 1.5 dB of deviation, and the range from 20 Hz to 3 kHz stays within about 1 dB of target, so bass, vocals and instruments sound natural and well proportioned. The catch: The presence and treble bands sit about 2.3 to 3.1 dB below target with a 5.7 dB dip near 10 kHz, so cymbals and fine detail come across a little subdued.
Buy the Moondrop Ultrasonic. It is rated higher for sound quality than the Simgot EA500 DSP and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
