You need to go into settings and choose the personal audio settings. There you can adjust left/right/front/back and height (they call it 3D). Then can you adjust the sound to a personal profile. Unfortunately, only one at a time.

 

Thanks. I’ve done all that many times but I just can’t seem to get it quite right. I’d prefer a traditional style equaliser.

 

Well, if that doesn't do it for you, I guess you are stuck. For me, it sounds great.
