I feel that the headset is a little heavy.

Please double check that you are wearing it correctly. It may improve if you tighten the belt on the top or sides of your head. If you feel like it's too heavy and hurts your neck, lean your neck back on a high-backed chair when you play. Also, there are differences in weight, comfort, and weight shift balance depending on the manufacturer, so it is a good idea to try different headsets on before purchasing.
