They’re No Lightweights
You’ll want to keep in mind that the AirPods Max weigh in at almost 385 grams, or 13.6 ounces, making them some of the heaviest premium over-ear headphones on the market — considerably heftier than the 260-gram Beats Studio3 and even the 310-gram Bose Quiet Comfort 35’s.
That said, Apple has promised that the ergonomic design of the AirPods Max should help to distribute the weight more uniformly than many other over-ear headphones, with a “breathable knit mesh” headband that suggests that the bulk of the weight is concentrated in the ear cups, so hopefully Apple has done enough to ensure that users will be able to wear them without too much fatigue, but if you’re concerned about that you might want to wait until the reviews start coming in, or at least make sure you order them directly from Apple so you can take advantage of the 14-day return policy.
