2.5mm
Audio jack size
2.5mm refers to a measurement of two and a half millimeters, commonly encountered as a standard size for audio jacks, knitting needles, and crochet hooks.
The 2.5mm audio jack is smaller than the common 3.5mm headphone jack and appears on some older phones, two-way radios, and compact devices: I need a 2.5mm to 3.5mm adapter for these headphones.
