Device

Iphone X

Operating System

iOS 12.3.1

I've been looking around but haven't found a suitable solution for the following:

I purchased Sennheiser CX 5.00i - In-ear headphones a while ago, but while listening to Spotify the music constantly pauses, skips, pauses, plays, pauses and so on. It's been frustrating and I would appreciate if there was a solution to this issue. The headphones aren't that cheap and the problem only popped up since a few weeks, I assume an automatic update. 

I read about the functionality of the headphones plugging in to a broken access center, but these headphones are specifically desgined for the Iphone. Weirdly enough it has a 3,5 jack plug, which requires a Lightning to Jack adapter.
