Short answer: the Campfire Audio Solaris Stellar Horizon. It ranks #1113 of 1398 in-ear headphones by sound quality (rated 3.0/5) at $1,799 and is still sold new; the Campfire Audio Solaris 2020 ranks #1223 (rated 2.4/5) and is discontinued, so it is only an option used.
Why pick the Campfire Audio Solaris 2020: A hybrid with a 10mm dynamic driver and three balanced armatures in a compact shell, and a published AutoEQ preset moves its response much closer to the Harman target. Watch for: Discontinued, so it is mainly found used.
The Campfire Audio Solaris Stellar Horizon is the better-sounding pick. A hybrid with one dynamic driver and three dual diaphragm balanced armatures in Campfire’s distinctive finish, with lower mids and the 1 to 2 kHz range within 1.5 dB of target, so voices have natural body. The tradeoff: Sub bass is almost 4 dB below target, presence is nearly 7 dB low with a 10 dB dip near 3.2 kHz, and an 8.5 dB peak near 10.9 kHz adds sharpness, so the response is uneven at 3.3 dB deviation.
