Is the Anker Soundcore Liberty 4 NC worth the upgrade from the EarFun Air Pro 4?
Verdict
Downgrade
The Anker Soundcore Liberty 4 NC actually scores 10.0 points below the EarFun Air Pro 4, so on aggregate review consensus this is a step backwards. The gains are concentrated in battery (7.0 to 8.0). You do give up ground on noise cancelling (8.0 to 7.0) and calls (7.5 to 6.5). On paper: driver size 10 mm to 11 mm. Worth checking: battery life goes 11 h to 10 h and codecs goes SBC, AAC, aptX, aptX Adaptive, aptX Lossless, LDAC to SBC, AAC, LDAC. One caution: this steps down a line tier (Air Pro 4 to Soundcore Liberty 4 NC), and base models usually trade away tier features - check the codec and ANC rows above before trusting the score gap alone. It is at least $24 cheaper, so the lower score comes with a saving. Only worth it if a specific feature above matters more to you than overall quality does.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
