Fit guide
Check over-ear fit before you commit
Over-ear headphones are a personal fit purchase. A product page can tell you its intended wearing style and listed mass; it cannot predict whether its cushions sit comfortably around your ears, whether the headband creates pressure, or whether your usual glasses affect the seal.
Check the whole contact path
With a candidate on your head, the cushions should sit around the ears rather than on top of them. Adjust the headband before judging the seal or sound. Confirm that hair, eyewear or a hat does not lift a pad away from the head. If you use glasses, inspect the area around the arms; a small gap can make the acoustic seal less consistent and may also change pressure. No one short fit check can promise comfort over a full day.
Use specifications as screening clues
Weight is an objective comparison point, but weight distribution and clamp force matter too. A listed weight does not tell you how the force is spread. Check the fit style, cushion material, headband adjustment and whether replacement cushions are available from an authorized source. If the maker does not publish a dimension you need, treat it as unknown instead of borrowing a measurement from a neighboring model.
The Sony WH-1000XM6 US support page lists an over-ear style and a weight of about 8.96 ounces. Sony's instructions say to extend and adjust the slider so the cups sit snugly over the ears, and note that poor positioning may feel uncomfortable or reduce noise-cancelling effect. Those facts make fit a pre-purchase check; they do not establish a universal comfort result.
Make the return policy part of the decision
Before ordering, check whether the retailer allows a fit trial, what condition is required for a return, and who pays shipping. Keep packaging and accessories until you know the set works for your own routine. Avoid judging fit only from promotional photos or a review that did not use your head shape and eyewear.
When trying the headphones, check comfort at first and after a realistic listening interval, then test the controls and modes you intend to use. Stop if the fit hurts or causes pressure. Use only the maker's cleaning instructions; cushion coatings may be damaged by unsuitable solvents or wet wipes.
Do not use fit as a safety guarantee
A snug fit can influence passive isolation and ANC, but it does not make headphones hearing protection or ensure awareness of outside sounds. Use ambient mode cautiously and remove headphones when full attention is needed. Water resistance is model-specific; do not infer it from a cushion's appearance or from another version in the same family.
