Is the Alienware Pro Wireless worth the upgrade from the Shure Srh840a?
Verdict
Meaningful upgrade
The Alienware Pro Wireless scores 8.8 points above the Shure Srh840a. That's a real improvement, though not the kind you'd notice on every track. The gains are concentrated in sound (8.0 to 8.7) and value (8.0 to 8.6). On paper: active noise cancelling, driver size 40 mm to 50 mm and usb-c. Worth checking: weight goes 273 g to 310 g. It's also $44 cheaper, which makes this an easy call. Worth doing if you're replacing anyway; harder to justify as a pure upgrade if what you have still works.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
