Whelp, I got my phantom X. It IS SNUG. Probably TOO snug. My mouth touches the liner in the front of the helmet, and it feels like it compresses my head. I measure 23.5" around, and bought the XXL. Audible pocket works well, and I don't notice it even with the snug fit. I don't like the 2-button (one on each side) visor latch even though it works pretty well and easily. It takes a little practice to get used to, and might be tough with gloves on. Id prefer a one button latch maybe right at the front. The liner is glued in instead of Velcro - which probably makes it last longer, but no way to adjust or modify it. Looks sleek, great FOV, nice visor. Nice helmet for someone with a normal size head. But that ain't me. I don't think Cookie's helmet fits any better though...
