Really impressive but battery gave up after 1 year of use. It shows that each one is fully charged but after taking out from case it was around 15%. Return to the seller and get my money back. Best part is the case with button/dial that was game changer for me.

The verdict
The CMF Buds Pro 2 punch well above their price point, offering solid sound quality and impressive ANC, with the innovative Smart Dial being the unexpected star of the show.
✓Liked: Good ANC, Smart Dial on case offers convenient controls, Comfortable, Nothing X app provides value
✕Could be better: Too much bass, No Multipoint (though dual device pairing is available)
