Is the Sony WH-1000XM3 worth the upgrade from the Austrian Audio Hi-X15?
Verdict
Marginal upgrade
There's only 2.0 points between the Austrian Audio Hi-X15 and the Sony WH-1000XM3. That's inside the range where two reviewers might simply disagree. It loses ground on value (9.0 to 8.0) and sound (8.5 to 8.0). On paper it adds active noise cancelling and usb-c. Worth checking: driver size goes 44 mm to 40 mm. It's also $39 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.

About this verdict
Direction matters here: this page answers "Hi-X15 to WH-1000XM3". The other direction is a separate question with a different answer. Scores blend published review verdicts across over-ear and shift as new reviews land, so a marginal call today may not be one next quarter.
