Difference in sound quality between codecs?

If there is (which of course there is) a percivable difference in sound quality between for example the new OPUS and the MP3 codec and their coding technology, what for example could that be?

Does the listening material have impact on the percived difference between the codecs, example if you are listening to speech or music?

I also presume that the percived difference also is different between people and target groups. What is your opinion about this?

One of the big differences for me between codecs is the hardware I'm using. I'm using a headset designed for speech, while it can play music quite fine compared to other headsets I've used, it does not handle bass very well. This was one of the reason Vorbis seemed to sound better for me (even over AAC), since from my observations, it reduced the bass when going to lower bitrates instead of preserving most of it and causing my headset to produce horrible sounds when at high volume.
Opus seems very similar to Vorbis in this matter and seems to sound far better than Vorbis and AAC at lower bitrates for me.

EDIT: Sorry, didn't read your question properly

Yes, especially when the codecs use different technology (transform vs. CELP).

Yes, experienced listeners often perceive differences differently (and perceive differences more easily) than naive listeners who have never done a listening test.
