EarFun Air Pro 4+
92 out of 100 low confidence 9 reviews
The EarFun Air Pro 4 earbuds deliver exceptional value, with users praising their high-end sound quality, effective noise cancellation, and robust battery life. Many reviewers note they outperform far more expensive competitors like AirPods Pro and Sony XM4s, especially after customizing the EQ via the app. A few minor issues include occasional fit adjustments and a quirk with single-bud Bluetooth connectivity, but overall sentiment is overwhelmingly positive.
Pros
- Excellent sound quality with LDAC and aptX Lossless
- Effective active noise cancellation
- Long battery life (11 hours per charge)
- Great value for money
- Comfortable and secure fit
Cons
- Single-bud Bluetooth connectivity quirk
- Occasional fit adjustments needed
- LDAC disables multipoint pairing
- Le Audio not working for some users
