Microphone issue on multiple Surface Pro Copilot+ devices

Afternoon, hoping someone can help with the below issue as we are not getting anywhere with it, the live chat hasnt been able to assist either.

We have purchased two Surface Pro Copilot+ devices and both of them have the same issue with their microphones where it pick up speech very quietly but it will pick up other noises much louder, for example when testing on the sound recorded app when talking loudly and also tapping on the surface pro, my talking plays back extremely quiet but the tapping is loud and clear.

We have installed all updates, ensured the microphone levels are high, disabled any microphone enhancements or effects but no luck. Has anyone else had this issue?

Thanks
