Short answer: the Master & Dynamic MW07, though neither ranks well in its class. It ranks #424 of 450 in-ear headphones by sound quality, rated 2.3/5, at $163.57. The Etymotic ER2SE ranks #432, rated 2.0/5, at $149.99, $13.58 cheaper, a saving that is not big enough to make up the sound-quality gap. Both are rated below 3.0/5 among the 450 in-ear headphones; for better sound, the Truthear Nova ranks #2 at $169.99.
The case for the Master & Dynamic MW07: These true wireless earbuds support aptX alongside SBC for better quality from compatible Android phones, and an IPX4 rating protects them against sweat and splashes. The tradeoff: Crinacle’s measurement gives it a preference score of 53, far from the balance most listeners prefer.
What the Etymotic ER2SE does well: Listeners who want a flat, diffuse field style sound get midrange that stays within about 1 dB of target from 200 Hz to 3 kHz, with no peak larger than 2.1 dB across the upper range. The tradeoff: In oratory1990’s measurement sub-bass is about 10 dB below target and falls 6 dB short by 71 Hz, so pop, hip hop and electronic music sound thin.
Buy the Master & Dynamic MW07. It is rated higher for sound quality, and the $13.58 saving on the Etymotic ER2SE is not enough to make up the difference.

Master & Dynamic MW07: $163.57 TWS Amazon eBay
Pros: These true wireless earbuds support aptX alongside SBC for better quality from compatible Android phones, and an IPX4 rating protects them against sweat and splashes. A built-in microphone handles calls, and the case extends total playtime to about 14 hours.
Cons: Crinacle’s measurement gives it a preference score of 53, far from the balance most listeners prefer. Battery life is only about 3.5 hours per charge, there is no active noise cancelling, and Bluetooth 4.2 is dated. The Jabra Elite Active 65t rates higher at a similar price.

Etymotic ER2SE: $149.99 B&H Photo Video eBay
Pros: Listeners who want a flat, diffuse field style sound get midrange that stays within about 1 dB of target from 200 Hz to 3 kHz, with no peak larger than 2.1 dB across the upper range. That keeps voices and acoustic instruments uncolored and free of harshness. The 15 ohm dynamic driver is an easy load for a phone.
Cons: In oratory1990’s measurement sub-bass is about 10 dB below target and falls 6 dB short by 71 Hz, so pop, hip hop and electronic music sound thin. Treble also runs about 6 dB low from 6 to 10 kHz with a 9.5 dB dip near 11.8 kHz, which dulls air and sparkle.
