A 4.8 puts its audio quality in the top half of wireless earbuds we've measured.
Measured on 64 of the 271 we've cataloged.
below average for wireless earbuds — based on 243 of 271 we've cataloged.
below average for wireless earbuds — based on 245 of 271 we've cataloged.

At $129, the Edifier NeoBuds Pro 2 are a steal. They're not perfect, but the only group of people we don't recommend these to are frequent international travelers. For everyone else, this is a good buy.
Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Measured frequency response (dB) against the SoundGuys house target — the dashed curve. The closer the measured line tracks the target, the more neutral the tuning; peaks ride above the target, dips fall below it.
