My experience with center image in music is that it tends to sound more “in your head.” The only way to really get a truly out of your head experience with headphones is when a track is mixed with that in mind or if you use an audio engine/dsp to simulate it.

Headphones are stereo devices by default. Good imaging on a stereo spectrum means pinpoint positioning of audio between far left and far right.

I commonly see people mention imaging in gaming and while it can be achieved (there are many game engines that support positional audio as well as simulate surround audio) the reality is that not all games support imaging through headphones. So keep that in mind if you plan to use your headphones for gaming.
