Query: A let-down

Jabra C150 Headset for 2.5mm Universal Headset PlugShould've researched further: although the data sheet mentions "Call answer/End" button, and the picture shows it, it does not work (at least with my Samsung phone). I used to have a headset like that and liked it a lot, until it broke; this I bought as a replacement and was really disappointed. The original one had 4 contact bands on the 2.5 mm plug, but the picture does not show the plug! (And there is not way to comment that picture is not showing enough details - Amazon, are you listening?)
