Is the Sony WH-1000XM4 worth the upgrade from the AceZone A-Spire Wireless?
Verdict
Marginal upgrade
There's only 4.0 points between the AceZone A-Spire Wireless and the Sony WH-1000XM4. That's inside the range where two reviewers might simply disagree. The gains are concentrated in value (6.5 to 8.0), sound (8.5 to 9.0) and noise cancelling (8.5 to 9.0). On paper: battery life 35 h to 38 h, weight 289 g to 254 g and multipoint pairing. Worth checking: bluetooth goes 5.4 to 5 and microphones goes 3 to 2. It's also $69 cheaper, which makes this an easy call. Keep what you have unless a specific feature above is the thing you're missing - the overall quality gap won't be what convinces you.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
