What to Look For
Key factors to consider before buying on AliExpress
Common chips: CS43131, CS43198, ES9219, AK4493 — all are competent. Implementation matters more than the chip. Output power determines which headphones you can drive.
For IEMs: 30-50mW is plenty. For full-size headphones: 100mW+ recommended. Balanced 4.4mm output offers higher power and lower crosstalk than single-ended 3.5mm.
UAC 1.0 support is needed for PS4/PS5/Switch. iOS may require a Lightning/USB-C adapter. Android supports USB audio natively. Some dongles have hardware volume buttons.

77FAQ
For 90% of IEMs, yes. It measures exceptionally well for $9 with clean output and sufficient power. Only upgrade for power-hungry planars or balanced output.
Balanced offers higher power and lower crosstalk. The difference is subtle with IEMs but noticeable with full-size headphones.
