Short answer: the TFZ T2 Galaxy. Both are rated 3.6/5 for sound quality (#686 and #697 of 1291 in-ear headphones), and the TFZ T2 Galaxy costs $59 against $68 for the Sony WF-C510, with sound quality a draw, the lower price decides it.
Why pick the Sony WF-C510: In hobbyist measurements on squig.link it tracks the Harman target closely through the bass and mids, with a preference score of 69 and no peak above target between 1.5 and 12 kHz, so it never sounds harsh. The tradeoff: There is no active noise cancelling, and codec support stops at SBC and AAC.
The case for the TFZ T2 Galaxy: Oratory1990’s measurement shows sub-bass about 3.7 dB and bass about 3.5 dB above the Harman target, which gives kick drums and bass lines a solid, punchy foundation that suits bassy and V-shaped tastes. The tradeoff: A peak of 4.9 dB near 8 kHz can make cymbals and sibilant vocals sound sharp.
Buy the TFZ T2 Galaxy. Both are rated the same for sound quality, and it costs $9 less than the Sony WF-C510.
