Short answer: the Westone W10, though neither ranks well in its class. It ranks #1182 of 1291 in-ear headphones by sound quality, rated 1.8/5, at $199.99. The Sennheiser IE 300 ranks #1190, rated 1.7/5, at $179.95, $20.04 cheaper, which does not close the gap in sound quality. 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.
What the Westone W10 does well: Its 122 dB SPL/mW sensitivity means a phone drives it to loud levels with no effort, and the cable includes a built-in microphone for calls. The catch: Oratory1990’s measurement shows heavy treble loss, with an 11.5 dB dip near 6 kHz and the air band almost 18 dB below target, so cymbals, string texture and spatial cues are badly muted.
What the Sennheiser IE 300 does well: 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.
Buy the Westone W10. It is rated higher for sound quality, and the $20.04 saving on the Sennheiser IE 300 is not enough to make up the difference.
