Short answer: the Shozy B2, though neither ranks well in its class. It ranks #1189 of 1291 in-ear headphones by sound quality, rated 1.7/5, at $169.99; the Sennheiser Momentum True Wireless ranks #1211, rated 1.5/5, and costs $180, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 1291 in-ear headphones; for better sound, the Truthear Nova ranks #2 at $169.99.
What the Shozy B2 does well: The closed in-ear design blocks outside noise and keeps music private. The catch: Crinacle’s measurement gives it a preference score of only 46 with 4.0 dB of deviation from the Harman target, so most listeners will hear it as noticeably colored.
The case for the Sennheiser Momentum True Wireless: Bass is lifted about 2.5 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Watch for: Presence sits about 10.9 dB low with a 12.4 dB dip near 4.0 kHz, so vocals and instruments lose some bite.
Buy the Shozy B2. It is rated higher for sound quality than the Sennheiser Momentum True Wireless and costs less, so only choose the other one for a particular feature it does better.
