Is the Shure Srh440a worth the upgrade from the 1MORE SonoFlow Pro HQ51?
Verdict
Downgrade
The Shure Srh440a actually scores 12.4 points below the 1MORE SonoFlow Pro HQ51, so on aggregate review consensus this is a step backwards. It loses ground on value (9.5 to 7.5) and sound (7.9 to 7.0). Worth checking: active noise cancelling goes Yes to No and weight goes 246 g to 268 g. One caution: this steps down a line tier (SonoFlow Pro HQ51 to Srh440a), and base models usually trade away tier features - check the codec and ANC rows above before trusting the score gap alone. And it costs $8 more for a lower score, which is hard to justify on the data alone. 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.
