I have had my iphone 5s (still have version 7.1.1) for three years now and never have encountered such a problem until recently.
When I plug my earphones, it works well depending on whether i want to facetime or play music but lately, it frequently stops, skips, pauses songs or activate Siri on its own accord. It even ends my facetime calls while i'm talking, so i have to call back every time (I can call back for more than 7-10 times).
Can someone help me???
PS: it never does this when its not connected to my headphones

You need a new headset.
The symptoms you are describing is because the "controller" assembly of your headset (the part that has the buttons and the microphone) is failing; most likely due to moisture (or some other contaminant) getting in and interfering with the circuitry.
I have had this happen to me on several occasions and not just limited to Apple headsets. Get a good quality headset that is also water resistant like the Bose SoundSport and you shouldn't have this problem again. (Going on 4 years with my Bose where I wouldn't last a year with the regular ones).
