With nicer connectors, and non-standard connectors, there's usually additional manufacturing cost involved that makes for expensive plugs and cables. As such the standards get driven by every manufacturer wanting to save a few pennies on I/O, while acknowledging that some applications might prefer quick removal or a secure lock.
I have a pair of high-end AKG headphones that uses a "mini-XLR" connection. This is a non-standard variant of the popular 3-pin XLR used throughout pro audio equipment. When the provided cable that converts mini-XLR to 3.5mm TRS started failing, I went onto Amazon and found a generic $11 cable, but within a week of use it became clear that it was poorly made, with a metal cap acting as the only source of strain relief.
I've ordered another adapter, one that adapts the plug to 3.5mm without a cable, and it also costs $11. Not as bad cost-wise as some Apple device cables, but fingers crossed.
