Welcome to the Two Wheeled Texans community! 
Feel free to hang out and lurk as long as you like. However, we would like to encourage you to 
I have a beloved HJC RPHA70ST .. that's their full-face "sport touring" helmet. Fits great. I wouldn't change a thing. In fact, after my wreck, I replaced the crashed RPHA70ST with a new one just like it.
Once I got a cheap bluetooth comms kit for my RPHA helmet, and it was unusable because the earphones smashed against my ears. I figured it was because it was a cheap setup and maybe a "real" brand BT comms setup like Cardo or Sena would be a better fit. In fact, HJC has a partnership with Cardo and there's even a special version of one of the Cardo kits that is made to work with these RPHA helmets in a more seamless manner.
I recently bought a Cardo Freecom 2+ used from another member. It also doesn't work with the RPHA helmet. It's not the special setup that's supposed to work best with these helmets, but the earphones part is the same, and it's the part that doesn't fit.
My research indicates everyone has this same issue with RPHA helmets. The ear cups are too shallow and you can't fit earphones in there, even though it comes stock with velcro in there to accommodate them. Some owners have cut the plastic that's under the earcup and mounted earphones straight the foam, and others even took a dremel to the foam which seems like a really bad idea. Removing the plastic is only going to give me another couple of mm max and I need like 8-10 mm more clearance for this to fit. I guess that's what you get with a lightweight helmet with less wind profile; the shell is more compact and it doesn't have enough room for ears plus earphones.
I think the solution I am going to try is IEMs with a short cable and just put the IEMs in my ears before I put the helmet on, then plug them in. It's a crummy solution, but at least it will work and be comfortable enough to wear for long periods.
BTW the Cardo rig fits fine and is comfortable on my LS2 helmet, which I tend to wear on low speed rides, like on my scooter. That helmet is brilliantly comfortable too, but it's a 3/4 helmet so to me it's only a special use helmet. I do have a fancy FF carbon fiber LS2 helmet on my wish list. This ear room issue is enough to make me consider getting the LS2 to replace my RPHA when it hits the 5 year mark.
