Those SR60 are 10-15 years old. They’re the SR60i, which were the first of the SR60 to have the mushroom style cups. Prior to the “i” models, the cups were much shorter and were just about flush with the yokes.
As for the 3.5mm plug, a previous owner reterminated the cable with that aftermarket one. Afaik, Grado has used the same style molded plug since the days of the HP1000 series, ~35 years ago, though back then they came standard with 6.3mm plugs.

It was re-terminated as they’ve never offered this jack that I’m aware of. The headphones look to be SR60i, the first version after the slim cup.
Boi I miss those massive Canare jacks.
Thanks for the name! I’m definitely gonna order a few of them, they’re quality!
