Short answer: the KZ EDX Pro 2. It ranks #561 of 1084 in-ear headphones by sound quality (rated 3.7/5); the KZ EDX Pro ranks #856 (rated 2.7/5).
The KZ EDX Pro 2 is the better-sounding pick. A very cheap single dynamic IEM, the second generation EDX Pro. The catch: Treble sits about 2.9 dB below target, a dark, relaxed balance.
The case for the KZ EDX Pro: It costs very little and is easy to drive, with 24 ohm impedance and a 112 dB sensitivity rating that suit a phone. The catch: Crinacle’s measurement gives it a preference score of 58, well short of what most listeners prefer.
