Is the Xiaomi Redmi Buds 4 worth the upgrade from the Xiaomi Redmi Buds 6 Pro?
Verdict
Downgrade
The Xiaomi Redmi Buds 4 actually scores 10.0 points below the Xiaomi Redmi Buds 6 Pro, so on aggregate review consensus this is a step backwards. The gains are concentrated in calls (6.0 to 7.0). You do give up ground on noise cancelling (7.5 to 5.5) and battery (8.0 to 6.0). On paper it adds wear detection. Worth checking: battery life goes 9.5 h to 6 h and codecs goes SBC, AAC, LDAC to SBC, AAC. One caution: this steps down a line tier (Redmi Buds 6 Pro to Redmi Buds 4), 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 $53 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.
