Hello, headphones produce different spatial perception than loudspeakers. For me, they are unnatural. The sound is inside my head, not in front of me. This is the nature of headphone listening.
If you reverse the phase of one channel, the sound comes from "the outer space", but that is also unnatural, just a different way.
Probably there is nothing wrong with your headphones. Try the samples here:

If you are in doubt, try with a pair of earphones that come with smartphones. They should deliver the same spatial sensation as your headphones do.
