Measured headphones.
Every headphone on this page was measured on our own bench, seated deliberately for the best fit, published as one real seating rather than a blend, with its limits named. The list is short on purpose: it only holds what we have actually measured, and it grows one headphone at a time. Send one in and it joins them.

Every measurement here is a starting point. Attune lets you audition a tuning on your own music and keep the one you'd pick with your eyes closed.
