Short answer: the Sennheiser IE 300, though neither ranks well in its class. It ranks #813 of 865 in-ear headphones by sound quality (rated 1.7/5) at $179.95 and is still sold new; the Sennheiser IE 800 ranks #827 (rated 1.6/5) and is discontinued, so it is only an option used. Both are rated below 3.0/5 among the 865 in-ear headphones, and the ThieAudio Monarch MKIII, ranked #1 at $999, is a better place to start if sound quality matters.
Why pick 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.
The case for the Sennheiser IE 800: Bass is lifted about 2.8 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Watch for: Discontinued, so it is mainly found used.
Buy the Sennheiser IE 300. It is rated higher for sound quality, and the Sennheiser IE 800 is discontinued, so it is only available used.

Sennheiser IE 800 Discontinued eBay
Pros: Bass is lifted about 2.8 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Lower mids sit within about 0.6 dB of target, keeping voices and guitars natural. It uses 1 x 7mm dynamic with an easy 16 ohm load.
Cons: Discontinued, so it is mainly found used. Presence sits about 8.4 dB low with a 10.8 dB dip near 3.5 kHz, so vocals and instruments lose some bite. A 6.7 dB peak near 10.8 kHz can make cymbals and sibilance sound sharp. A Harman score of 44 places it in the lower part of the in-ear rankings.
