Short answer: the DUNU Titan S2. Both are rated 4.4/5 for sound quality (#172 and #180 of 1291 in-ear headphones), and the DUNU Titan S2 costs $79.99 against $90.99 for the Simgot EA500 DSP, so with nothing between them on sound quality, price settles it.
Why pick the DUNU Titan S2: The median of 25 hobbyist measurements gives it a very good Harman preference score of 78 with a 1.72 dB spread, and its mids sit within about 1.2 dB of target, so vocals and instruments sound natural. The tradeoff: Sub-bass is 2.5 dB short at 30 Hz, so deep bass lacks rumble.
Why pick 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. Watch for: 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 DUNU Titan S2. Both are rated the same for sound quality, and it costs $11 less than the Simgot EA500 DSP.
