Is the Sennheiser MOMENTUM 3 Wireless worth the upgrade from the Austrian Audio Hi-X15?
Verdict
Downgrade
The Sennheiser MOMENTUM 3 Wireless actually scores 6.0 points below the Austrian Audio Hi-X15, so on aggregate review consensus this is a step backwards. It loses ground on value (9.0 to 6.5). On paper it adds active noise cancelling, multipoint pairing and water resistance (IPX4). Worth checking: weight goes 255 g to 305 g and driver size goes 44 mm to 42 mm. And it costs $66 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.
