Glasses work, as do over your ears, or clipped to a baseball cap. The higher the better, and *don't move your head*. The ideal spot to stand is at the tip of an equilateral triangle formed by you and the two speaker stacks, but that assumes an acoustically perfect venue and a sound engineer who knows what he's doing...I wouldn't say the closer to the stack the better, because you could get all low end and have the high end fly over your head...10-15 feet from the stacks will likely yield a better result...
