VolumeCare will break the "Sound Barrier" on your Treo! You will now hear people loud and clear! Volume Care increases the maximum volume levels for each Treo speaker. Studies have proven volume increases up to a 250% in handset volume, speaker phone volume and wired headset volume. VolumeCare will also allow you to adjust your voice volume (microphone) so others will hear you loud and clear. VolumeCare also allows you to set pre-defined default volume listening levels for each speaker type on your Treo. So you can preset the listening level for your earpiece separately from the Speaker Phone.
