Short answer: the KZ PR2. It ranks #101 of 450 in-ear headphones by sound quality, rated 4.4/5, at $51.25; the Rose Technics QT-X ranks #150, rated 4.3/5, at $50.99. With prices this close, go by the sound-quality ranking rather than the cost.
Why pick the KZ PR2: Its 13.2 mm planar driver scores 78.8 in the median of 13 squig.link measurements, with bass and mids held within about 1 dB of target from 20 Hz to 3 kHz. Watch for: At 94 dB sensitivity it needs noticeably more volume than most in-ears, so weak phone outputs may run out of headroom.
Buy the KZ PR2. It is rated higher for sound quality, and the $0.26 you would save on the Rose Technics QT-X does not close the gap.

Pros: Its 13.2 mm planar driver scores 78.8 in the median of 13 squig.link measurements, with bass and mids held within about 1 dB of target from 20 Hz to 3 kHz. Sub-bass sits 0.9 dB above target and extends fully to 20 Hz, so it delivers clean, solid low end. A strong 7.4 dB lift in the air band gives an open, detailed top that suits listeners who like a v-shaped sparkle.
Cons: At 94 dB sensitivity it needs noticeably more volume than most in-ears, so weak phone outputs may run out of headroom. The 6.4 dB peak near 10 kHz alongside a 4.3 dB dip near 6.7 kHz can make treble sound uneven, with cymbals that sizzle while some vocal edge recedes.
