If you can't tell the difference between some CODECs there's something wrong with your ears. As I mentioned, some are designed to squeeze as many voice channels as possible out of a given bandwidth. They are quite noticeable, compared to the standard G.711 CODEC and the wider ones can provide a noticeable improvement. Even with CODECs for music, you can sometimes catch an artifact of the compression. One example of this I have come across is the Beatles "A day in the life.". There is one soft stretch where the audio is dead centre between the left & right tracks, which I can hear on the CD, but not with the MP3 version.
