Query: Bad sound quality

I am dissapointed with the bad quality of the sound and the large difference between the volume you hear your own voice and that you hear from the caller. If you adjust the volume to hear your caller well, then you can go deaf when you hear your own voice! Really annoying. The quality of the sound to hear recorded messages is also bad. After a few months I bought a new phone. At least it was cheap...
