3.5mm

Headphone connector size

3.5mm refers to the diameter of the standard audio jack used for headphones, earbuds, and auxiliary cables—also called a headphone jack or aux jack: My new phone doesn't have a 3.5mm port.

The connector has been ubiquitous on portable audio devices since the Walkman era, though some manufacturers have eliminated it in favor of wireless or USB-C audio.
