Does my MacBook Pro 3.5mm audio jack accept microphone input? How do I find out whether the 3.5mm audio jack on the side of my MacBook Pro (2.9 GHz Dual-Core Intel Core i5, early 2015) allows audio input from a headset microphone.  (I need a headset for Zoom).
All PowerBook and MacBook models support TRRS style audio input. Check with the vendor of your headset if you want to use any buttons or volume control if you have questions. Apple branded headphones work well, as do many third party options.
