Short answer: the JBL Tour Pro 3. It ranks #22 of 1291 in-ear headphones by sound quality, rated 4.9/5, at $229.95; the Sonic Memory SM2 ranks #42, rated 4.7/5, and costs $249, which makes this an easy call rather than a real tradeoff.
Why pick the JBL Tour Pro 3: True wireless ANC earbuds with an 84.7 preference score, an exceptionally smooth 1 dB deviation from target, IP55 protection and LDAC. The tradeoff: Air above 10 kHz runs about 3 dB above target, adding a little extra shimmer that some listeners may find slightly bright.
What the Sonic Memory SM2 does well: Tuned close to the Harman target that most listeners prefer in blind tests (preference score 83). Watch for: The rating reflects sound quality only; comfort, build and noise isolation are not part of the score.
Buy the JBL Tour Pro 3. It is rated higher for sound quality than the Sonic Memory SM2 and costs less, so only choose the other one for a particular feature it does better.
