Short answer: the TANGZU TianPeng. It ranks #104 of 450 in-ear headphones by sound quality, rated 4.4/5, at $629; the FlipEars Aisha Electri ranks #173, rated 4.3/5, and costs $699, so there is not much of a tradeoff to weigh.
What the TANGZU TianPeng does well: Squig.link measurements from six hobbyists give the TianPeng a preference score of 79.1 with a tidy 1.43 dB deviation, so its eight driver hybrid of dynamic, balanced armature and bone conduction units hangs together coherently. The tradeoff: A 4.5 dB dip near 4.1 kHz and a presence band 2.3 dB below target take some bite out of vocals and guitars, which can sound slightly veiled.
Buy the TANGZU TianPeng. It is rated higher for sound quality than the FlipEars Aisha Electri and costs less, which makes it the one to get unless you need something the other one does better.

TANGZU TianPeng: $629.00 Linsoul eBay
Pros: Squig.link measurements from six hobbyists give the TianPeng a preference score of 79.1 with a tidy 1.43 dB deviation, so its eight driver hybrid of dynamic, balanced armature and bone conduction units hangs together coherently. Sub-bass sits 1.7 dB above target and bass 1.1 dB above, a warm, full low end that suits bass lovers without smearing the mids. Treble stays restrained, with nothing above about 4.7 dB over target, so it is easy to listen to for hours.
Cons: A 4.5 dB dip near 4.1 kHz and a presence band 2.3 dB below target take some bite out of vocals and guitars, which can sound slightly veiled. The low 9.8 ohm impedance may let some sources color the sound, and it costs well more than the equally rated Unique Melody 3DT while trailing the higher rated Myer Audio CKLVX D62.
