Personally I find the call quality much better than past xperia phones I have had by far and it is loud enough for me. Haven't had a problem hearing anyone yet. Louder than other brand phones I have had as well like the HTC inspire and Motorola atrix. The speaker is decently loud and I usually have to turn it down. The only time it isn't loud is after its been under water for the next 15-30 minutes. I love the waterproof feature. I don't think I could go back.
The flaps is personally preference but I kinda get annoyed having to undo them but at same time every phone I have had without them I get more annoyed by seeing how much dirt gets in those usb sockets etc. I live the clean design with closed flaps. I also have bluetooth installed in my car now so don't have to worry about the auxiliary socket often and only take the charger one off at night.
But to each his own.
