Poor Audio Quality

Just purchase ring Pro I'm satisfied with everything except the audio quality. Someone rings the bell they cannot understand what I am saying it sounds garbled like I am talking through a a vibrating tin can. I maybe can understand 1/3 what the person is saying on the inside of the house. I have strong WiFi I even tried the ring Wi-Fi extender my RSSI is at 50. I have a 24 volt 40 VA Transformer I set it up to bypass the doorbell I also tried powering it through the doorbell. Unless someone has any other ideas I am at the end of my rope. I don't know I just got a defective one or not. I am contemplating going to a different brand of video doorbell
