The Ruling
The Bose QuietComfort 45 Headphones wins Isolation — but only just, and the rest of the chart is close. It is the pricier of the two at $329, so the Beyerdynamic DT 900 PRO X Headphones stays the pick if $9.01 matters more than those specs.
At a Glance
Every axis is scored out of 10 from the catalog specs below. The scores are relative to the products on this page, so a 10 means “best of these”, not “perfect”, and two identical columns mean the catalog genuinely cannot separate them. Axes the catalog holds no figure for on both sides are left off entirely rather than guessed at.
