The letter is the published assessment. Missing factor evidence is labeled; it does not become a zero.
Why this grade
Historically the most repairable earbud line: WF-1000XM3 scored 5/10 and WF-1000XM4 7/10, with earbud batteries replaceable using widely available standard Z55H coin cells and a modular case battery/port (XM4). However iFixit reports Sony 'nerfed' the line — each generation needs more tools just for a battery swap, and the WF-1000XM5 abandons the replaceable-battery design. No official replacement parts or repair instructions (community/iFixit guides only); no smartwatch line. Cheap coin-cell parts and no activation lock are pluses, but absent OEM support keeps it at F.
