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 Westone W20 ranks #447, rated 1.0/5, and costs $249.95, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 450 in-ear headphones, and the Truthear Nova, ranked #2 at $169.99, is a better place to start if sound quality matters.
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. Watch for: 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.
The case for the Westone W20: Two balanced armature drivers and a 117 dB/mW sensitivity make it easy to drive loud from a phone. Watch for: A preference score of 35 in crinacle’s measurement puts its tuning far from the Harman target, so it will sound colored to most listeners without EQ.
Buy the Sennheiser Momentum True Wireless 2. It is rated higher for sound quality than the Westone W20 and costs less, which makes it the one to get unless you need something the other one 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.

Pros: Two balanced armature drivers and a 117 dB/mW sensitivity make it easy to drive loud from a phone. It includes a built in microphone for calls, and the closed in-ear design blocks outside noise.
Cons: A preference score of 35 in crinacle’s measurement puts its tuning far from the Harman target, so it will sound colored to most listeners without EQ. The claimed response stops at 18 kHz, and the Oriolus Finschi Hifi rates higher and costs less.
