Hey shooter,
We actually posted a blog article not too long ago talking about helmets/headsets/installation and in Step Four we share why we think it's important to have a headset properly installed. As a side note, and as the article states, some helmets require little to no installation while others tend to be a bit more complicated. It all depends.
