Manufacturer-stated mass of one earbud, plotted only when both sources state a per-earbud figure. The charging case is separate. This is not a comfort or fit rating.
Start with your listening environment. Open and closed earcups suit different surroundings. A closed back is not the same as active noise cancellation. Check the exact cable and headphone output. We do not turn impedance, driver size or unpaired lab results into a sound-quality score.
