Is the EarFun Air Pro 4 worth the upgrade from the Anker Soundcore Liberty 4 NC?
Verdict
Clear upgrade
Going from the Anker Soundcore Liberty 4 NC to the EarFun Air Pro 4 buys you 10.0 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in noise cancelling (7.0 to 8.0), calls (6.5 to 7.5) and sound (7.5 to 8.0). You do give up ground on battery (8.0 to 7.0). On paper: battery life 10 h to 11 h, codecs SBC, AAC, LDAC to SBC, AAC, aptX, aptX Adaptive, aptX Lossless, LDAC and bluetooth 5.3 to 5.4. Worth checking: driver size goes 11 mm to 10 mm. That costs $24 more, or about $2 per point of score - reasonable value for the jump. If your current pair is worn out or the gains line up with how you listen, this one is worth the money.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
