Full Definition & Technical Explanation
Headphone jack (3.5mm) lets you plug wired headphones without adapters. Many flagships removed it (see Headphone audio jack: No) to save space and push wireless audio.
Laptops usually keep one. Wired still gives lossless audio with no battery. See codecs for wireless quality.
