I was one of those that for years thought all the gadgets must be a distraction but I am entering my second season with Sena SMH-10s and can see where they actually RELAX me while riding.
My preference if I have to make a business trip of over an hour each way (and there's lots of those - and much longer) is take the bike, day or night in OK weather. Then I need to be available. With the old cell phone I'd feel it buzzing in my pocket, look for a safe place to pull over, shut 'er down, helmet off, earfoam out, fudge around for the phone. Now I'm annoyed and at risk on the shoulder or from goofs in a plaza parking lot and I don't even know what the call is about and I have to call back because by then the caller has hung up.
Switch to using Sena, I play some preselected music that's not crazy and it puts me in a groove where I'm alert and actually smoother on the controls - go figure. Phone call beeps me, tap the unit once "Yup; what's up?" yack yack - they usually don't even know I'm booting down the road on a motorcycle. Tap once again - hangup - music comes back on.
I use the second set for my pillion because riding is all new to her and being able to communicate helps with her confidence. And again, I ride mostly an hour or more without stops so it's nice to be able to chat instead of being mentally distracted as to wondering how she's doing back there.
Reference: Shoei TZ-R with foam ear plugs, volume for music nearly full on. Intercom and Phone volume a little lower. She has a Zox helmet, foam ear plugs. Foam plugs actually improve the sound at the ears - no high frequency hash.
