Lightning adapters keep failing

I have an iPhone XS Max and use a lightning adapter to connect my headphones.

I’ve recently had my fourth lightning adapter fail on me. The first 2 were official Apple ones, the last 2 were third party. In all instances the behaviour is the same - suddenly the music will stop coming through the headphones and start coming through the iPhone loudspeaker.

Some points of note:

• I have used a multitude of different headphones across the lifespan of these 4 adapters with the same results.
• The lightning port charges the phone without issue.
• The last 2 adapters failed within 2 weeks of each other.
• Originally when the first adapter failed i reported this to Apple and i managed to keep the case open for months. They physically cleaned the phone and wiped it, etc but refused to replace it.

Has anyone else had a similar experience to this?
