Is the Xiaomi Redmi Buds 4 worth the upgrade from the Sennheiser MOMENTUM True Wireless 2?
Verdict
Downgrade
The Xiaomi Redmi Buds 4 actually scores 16.0 points below the Sennheiser MOMENTUM True Wireless 2, so on aggregate review consensus this is a step backwards. The gains are concentrated in calls (6.0 to 7.0) and value (7.0 to 7.5). You do give up ground on sound (9.0 to 6.5) and noise cancelling (7.0 to 5.5). On paper: bluetooth 5.1 to 5.2 and driver size 7 mm to 10 mm. Worth checking: battery life goes 28 h to 6 h and codecs goes SBC, AAC, aptX to SBC, AAC. It is at least $55 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.
