Short answer: the Penon Fan 3. It ranks #675 of 1291 in-ear headphones by sound quality, rated 3.7/5, at $349; the Penon Dome ranks #744, rated 3.6/5, at $349. Close enough in price that the sound-quality gap is the deciding factor.
What the Penon Fan 3 does well: A broadly balanced tuning with a preference score of 70 against the Harman target. Watch for: An uneven response, 2.4 dB standard deviation from target.
Why pick the Penon Dome: A broadly balanced tuning with a preference score of 69 against the Harman target. The catch: Treble about 6 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the Penon Fan 3. It is rated higher for sound quality than the Penon Dome at the same price, so only choose the other one for a particular feature it does better.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
