Short answer: the Westone Pro X50, though neither ranks well in its class. Both are rated 1.0/5 for sound quality (#450 and #449 of 450 in-ear headphones), and the Westone Pro X50 costs $609.96 against $657.57 for the Final Audio F3100, and with sound quality even, the cheaper one is the better buy. Both are rated below 3.0/5 among the 450 in-ear headphones, so if sound quality matters, consider the Truthear Nova instead, ranked #2 at $169.99.
What the Final Audio F3100 does well: The single balanced armature has a 42 ohm load that suits phones and dongles without needing a separate amp. Watch for: Oratory1990’s measurement gives a preference score of only 25 with 5.83 dB of deviation, and sub-bass sits 12.8 dB below target, falling 6 dB short at 80 Hz, so bass has almost no weight.
The case for the Westone Pro X50: Five balanced armatures with 115 dB/mW sensitivity make it easy to drive from a phone or stage monitor pack. The tradeoff: Its preference score of 11 from crinacle’s measurement is among the lowest of any in-ear, with 6.39 dB of deviation and a strongly dark tilt, so its tonal balance is far from what most listeners prefer.
Buy the Westone Pro X50. Both are rated the same for sound quality, and it costs $47.61 less than the Final Audio F3100.

Final Audio F3100: $657.57 Amazon eBay
Pros: The single balanced armature has a 42 ohm load that suits phones and dongles without needing a separate amp. Its tuning fits listeners who favor a diffuse-field, studio-flat style of balance over a bass-forward one. It matches the rating of the Westone Pro X50.
Cons: Oratory1990’s measurement gives a preference score of only 25 with 5.83 dB of deviation, and sub-bass sits 12.8 dB below target, falling 6 dB short at 80 Hz, so bass has almost no weight. A 7.7 dB dip near 5.3 kHz next to a 5.7 dB peak around 8.3 kHz makes the treble uneven, with vocals recessed and sibilance accented. The Audio-Technica ATH-E70 and Mackie MP-360 rate higher and cost less.

Westone Pro X50: $609.96 Amazon eBay
Pros: Five balanced armatures with 115 dB/mW sensitivity make it easy to drive from a phone or stage monitor pack. The closed in-ear design isolates well from loud surroundings.
Cons: Its preference score of 11 from crinacle’s measurement is among the lowest of any in-ear, with 6.39 dB of deviation and a strongly dark tilt, so its tonal balance is far from what most listeners prefer. The Mackie MP-360 and Audio-Technica ATH-E70 earn higher ratings for less money.
