Is the Soundcore Liberty 4 Pro worth the upgrade from the Xiaomi Redmi Buds 4?
Verdict
Clear upgrade
Going from the Xiaomi Redmi Buds 4 to the Soundcore Liberty 4 Pro buys you 16.0 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in noise cancelling (5.5 to 8.0), sound (6.5 to 8.5) and battery (6.0 to 7.5). On paper: battery life 6 h to 10 h, codecs SBC, AAC to SBC, AAC, LDAC and bluetooth 5.2 to 5.3. That costs $120 more, or about $7 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.
