I think in all those situations an alternative newer option was made and existed in parallel gradually gaining support until the other older tech wasn't needed.

Personally I don't think I've ever seen anyone using wireless earbuds despite Bluetooth having been around a long time. Bluetooth earpieces for phone calls were common for a while, but more recently I've seen more people use a wired mic on their earphone cable.

It does seem likely to me that we'll move wireless with ear-buds but this transition seems much more forced than the others you've cited.
