Short answer: the Binary 1900. It ranks #116 of 450 in-ear headphones by sound quality, rated 4.4/5, at $239.99; the Aful Performer 7 ranks #167, rated 4.3/5, at $239.99. With prices this close, go by the sound-quality ranking rather than the cost.
What the Binary 1900 does well: In the median of 4 squig.link measurements it tracks the target closely from 20 Hz through 3 kHz, with every band from sub-bass to upper mids within 1 dB, for a preference score of 78.5. The tradeoff: A 5.8 dB dip near 5.7 kHz and a presence band about 4.1 dB below target take the edge off vocals and guitar attack, making some recordings sound distant.
Buy the Binary 1900. It is rated higher for sound quality than the Aful Performer 7 at the same price, which makes it the one to get unless you need something the other one does better.

Pros: In the median of 4 squig.link measurements it tracks the target closely from 20 Hz through 3 kHz, with every band from sub-bass to upper mids within 1 dB, for a preference score of 78.5. The dynamic driver paired with a passive radiator keeps bass extension full down to 20 Hz without overdoing it. At 124 dB SPL/V it gets loud easily from a phone dongle.
Cons: A 5.8 dB dip near 5.7 kHz and a presence band about 4.1 dB below target take the edge off vocals and guitar attack, making some recordings sound distant. Its 10 ohm impedance and high sensitivity make it prone to picking up background hiss from noisy sources.
