I fondly remember the Sony Ericsson Walkman series, which were phones intended to be one's personal music player. And they had Sony Ericsson's thick, wide, proprietary connectors. It was such an annoyance having to carry those earphones just for the phone, or when the included earphones (with the proprietary connectors) broke down and you couldn't just use another pair of earphones. A little while later, someone released an adapter, and that lessened the annoyance. But later phones that had 3.5mm (or 2.5mm) in-built were definitely better.
