    Here is a fix I got from ppcgeeks. You need to call sprint and speak with tier 2 tech support and have them enable EVRC-B and set Home Orig to EVRC-B.

    This improved voice clarity, and speaker phone quality as well. Volume also seemed to improve. I have not experienced any negative affects due to this change or any additional drain on battery life.

    To view:
    1) Open the phone dialer
    2) Type ##DATA# or (##3282#) (do not need to press anything else)
    3) When the screen pops up select view
    4) Then select advance
    5) Scroll down to you see EVRC-B and Home Orig (this is what need to be changed to improve voice quality).

    To enable EVRC-B:
    1) Open the phone dialer
    2) Type ##DATA# or (##3282#) (do not need to press anything else)
    3) When the screen pops up select edit
    4) You will be prompted for a password.
    5) Sprint will need to give you the password, the password is also your MSL#
    6) enter # given and save for later (maybe usefull if you root)
    7) Then select advance
    8) Tap to enable EVRC-B and then tap Home Orig to set EVRC-B there as well.
    9) Press menu and select "Commit Modifications" so that the changes take affect.
    10) You can now exit by press back.

    Hope this works for you.

    BTW I was not having issues before, but I did notice this setting worked better for me. This is the most current speech codec used by CDMA networks.

    I'm having problems with my earpiece, when the volume is set to max, the earpiece speaker sounds very distorted, almost as if the speaker is blown out.
    If I call sprint, will this fix my issue?

    I hope so, it wouldn't hurt to try. I would recommend this and report back, I would like to know as well.

    Just to clarify, can I enable EVRC-B on my own without calling Sprint, or is there something they need to do on their end? I already have my MSL, so I know I can get in there.

    Thanks.

    Nevermind....I just tried it and was able to make the switch with no problem. It may be a placebo effect, but I just made a call and I think it actually is better. Time will tell. Thank you very much for posting this!
