Hello SIMONDOLANBASS,
It sounds as though you're experiencing a clicking sound when using a headset with a third-party USB-C adapter. To confirm, have you tried a different adapter with your iPad Pro and this headset? If not and if you have an alternate adapter available, test to see if the issue persists. In addition to those steps, you'll want to complete the steps listed below. These steps are specific to resolving issues with wired headphones.
- "Check for debris in the headphone port on your iPhone, iPad or iPod touch.
- Check your headphone cable, connector, remote, and earbuds for damage, like wear or breakage.
- Look for debris on the meshes in each earbud. To remove debris, gently brush all openings with a small, soft-bristled brush that's clean and dry.
- Firmly plug your headphones back in. If your iOS device has a case, remove the case to get a firm connection.
If your headphones still aren't working, follow the steps below for your issue."
