Short answer: the Shuoer Cadenza 4. Both are rated 4.6/5 for sound quality (#48 and #49 of 450 in-ear headphones), and the Shuoer Cadenza 4 costs $249 against $269 for the Kinera Freya 2.0, and with sound quality even, the cheaper one is the better buy.
Why pick the Kinera Freya 2.0: Six hobbyist measurements on squig.link give it a preference score of 81.2 and a smooth 1.31 dB deviation. Watch for: The air band above 10 kHz falls about 3.4 dB short, with a 4.8 dB dip near 10.7 kHz, so recordings lose a little openness and shimmer.
Why pick the Shuoer Cadenza 4: The median of 23 squig.link measurements scores it 81.2 for preference with 1.4 dB of deviation, a consistent result across many units. Watch for: Presence between 3 and 6 kHz falls about 3.9 dB below target, which dulls the leading edge of voices and snare.
Buy the Shuoer Cadenza 4. Both are rated the same for sound quality, and it costs $20 less than the Kinera Freya 2.0.

The Two Headphones In Full
Kinera Freya 2.0: $269.00 Amazon eBay
Pros: Six hobbyist measurements on squig.link give it a preference score of 81.2 and a smooth 1.31 dB deviation. Bass sits about 1.6 dB above target while the mids stay within a fraction of a decibel, so it sounds warm and full without clouding vocals. At 3.6 g per earbud it is light, and 20 ohms with 105 dB sensitivity runs fine from a phone.
Cons: The air band above 10 kHz falls about 3.4 dB short, with a 4.8 dB dip near 10.7 kHz, so recordings lose a little openness and shimmer. A 4.6 dB peak near 8.1 kHz can emphasize sibilance on some vocals.

Shuoer Cadenza 4: $249.00 Amazon eBay
Pros: The median of 23 squig.link measurements scores it 81.2 for preference with 1.4 dB of deviation, a consistent result across many units. A dynamic driver and three balanced armatures deliver bass within about 2 dB of target at 30 Hz and a low mid lift near 1 dB that fills out vocals and piano. Treble from 6 to 16 kHz lands within half a dB of target on average, so the top end sounds natural rather than tilted.
Cons: Presence between 3 and 6 kHz falls about 3.9 dB below target, which dulls the leading edge of voices and snare. A 5.5 dB peak at 8.1 kHz next to a 5.1 dB dip at 11.5 kHz makes the treble a little uneven, and at 15 ohms and 102 dB it can pick up hiss from noisy sources.
