Short answer: the Shozy B2, though neither ranks well in its class. Both are rated 1.7/5 for sound quality (#1189 and #1190 of 1291 in-ear headphones), and the Shozy B2 costs $169.99 against $179.95 for the Sennheiser IE 300, and with sound quality even, the cheaper one is the better buy. Both are rated below 3.0/5 among the 1291 in-ear headphones, and the Truthear Nova, ranked #2 at $169.99, is a better place to start if sound quality matters.
The case for the Sennheiser IE 300: A compact, comfortable single dynamic IEM with a detachable cable and full bass about 4 dB above target that extends to 20 Hz. The tradeoff: The tuning measures poorly, with a Harman score of 46: presence sits about 5.6 dB low with a 7.7 dB dip near 3.2 kHz, while a 12.4 dB treble peak near 9.8 kHz can make cymbals and sibilance harsh.
What the Shozy B2 does well: The closed in-ear design blocks outside noise and keeps music private. Watch for: 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.
Buy the Shozy B2. Both are rated the same for sound quality, and it costs $9.96 less than the Sennheiser IE 300.
