I have used all my Sena's (on my second set) on 3/4 helmets. Speakers are of course mounted internally in the ear pockets and covered by the helmet, but the mike is a boom mike and "out in the open." Just took a call the other day while on 4 lane road at 60 ish or so. Questioned the caller to make sure he could hear me. He said sure and asked why? Told him I was on the bike at 60 and he said he was impressed, that it sounded better than most car blue tooth connections. Trick is to keep the mike right at your mouth, almost touching your lips, and making sure the mike is faced the right direction. There is a tab on the mike so you know which way is to face front.
Can't comment on hearing audio on a half helmet but as to in a 3/4 helmet it is absolutely fine. Have no problems communicating with passenger but her helmet is 3/4 as well.
