Ring Video Doorbell Pro Speaker Quality/Distortion

Hi. Just received my Doorbell Pro and set it up in the house to make sure it works etc. Was trying it all out including speaking through the app (iPhone). The sound quality through the Pro doorbell itself is really poor and easily distorts - rubbish quality speaker? Is this to be expected. It's not \*quite\* as bad if I talk more quietly through the app. Thanks in advance.
