That is my recollection as well. The standard was 1/8" for a long time, originally as a mono connector, until many personal electronics products manufactured outside of the USA started showing up with 3.5mm plugs & jacks. Had they wanted to adopt the existing standard but use metric naming, it could have been called 3 mm (.118"). I just mic'd a plug on a B&O (Danish company) earphone set at .1377" (3.5 mm x .03934 = .13769").
