A buyer who needs isolation should assess that requirement independently of whether the earcups are closed.

It would be misleading to average the entries, convert the secondary number into an apparently precise corrected specification, or assume that the discrepancy proves a different hardware version.

Then assess the fit over a realistic session and check the cable arrangement at your usual listening position. These are proposed checks derived from the documented benefits and limitations, not additional test results.
