Bluetooth headphones beeps when toggling play/pause buttons

Hello there!

I found a similar topic in the community, and there was the solution to turn off audio feedback, maybe this can help?

Here is the hole article: earbuds beeping noise when toggling pause… - Apple Community

And this is another article from Apple: If the sound from your wireless headphones cuts out or is distorted - Apple Support

Hope this helps!

Try and restart the bluetooth device and the paired iPhone to see if the issue is persisting
