Short answer: the Sennheiser Momentum True Wireless 2, though neither ranks well in its class. It ranks #441 of 450 in-ear headphones by sound quality, rated 1.6/5, at $243.44; the EarSonics ES2 ranks #448, rated 1.0/5, and costs $289.99, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 450 in-ear headphones, so if sound quality matters, consider the Truthear Nova instead, ranked #2 at $169.99.
The Sennheiser Momentum True Wireless 2 is the better-sounding choice. Active noise cancelling, Bluetooth 5.1 with SBC, AAC and aptX, and an IPX4 rating cover the features commuters and gym users want. The catch: In oratory1990’s measurement the presence region from 3 to 6 kHz is about 9.6 dB below target, with a 10.7 dB dip near 4 kHz, so vocals and instrument attack sound pushed back and hazy.
What the EarSonics ES2 does well: Two balanced armature drivers and a very high 119 dB/mW sensitivity mean it reaches loud levels from any phone or dongle with little effort. Watch for: Crinacle’s measurement gives it a preference score of only 29, one of the furthest from the Harman target among in-ears, so its tonal balance will sound off to most listeners without EQ.
Buy the Sennheiser Momentum True Wireless 2. It is rated higher for sound quality than the EarSonics ES2 and costs less, so only choose the other one for a particular feature it does better.

The Two Headphones In Full
Sennheiser Momentum True Wireless 2: $243.44 TWS Amazon eBay
Pros: Active noise cancelling, Bluetooth 5.1 with SBC, AAC and aptX, and an IPX4 rating cover the features commuters and gym users want. Battery life is rated at 7 hours per charge and 28 with the case, and each earbud weighs only 6 g. Bass is lifted by about 3.1 dB over target, which suits listeners who want a warm, punchy sound.
Cons: In oratory1990’s measurement the presence region from 3 to 6 kHz is about 9.6 dB below target, with a 10.7 dB dip near 4 kHz, so vocals and instrument attack sound pushed back and hazy. A 5.2 dB peak near 10.8 kHz and boosted air then add an uneven sparkle on top, and sub-bass is down 2.3 dB. The preference score of 44 is low, and the rating sits below the Jabra Elite Active 65t.

EarSonics ES2: $289.99 Amazon eBay
Pros: Two balanced armature drivers and a very high 119 dB/mW sensitivity mean it reaches loud levels from any phone or dongle with little effort. The closed in-ear design isolates well from outside noise.
Cons: Crinacle’s measurement gives it a preference score of only 29, one of the furthest from the Harman target among in-ears, so its tonal balance will sound off to most listeners without EQ. The Oriolus Finschi Hifi rates higher and costs less, and the Westone W20 matches its rating for less money.
