was just on a trip this past weekend and felt like listening to some tunes... half helmet with earplugs and I had no problem hearing it. It's not a Bose home theater, but doesn't sound bad.

The key to hearing the stereo is wear ear plugs as Jerm21 said . that knocks out all the wind noise
. Only way i will ride the super slabis with plugs in. I use the cheap disposable from work.
Gonna be different for everyone based on windshield height, your height, helmet type/fit, earplugs. I couldn't hear it well with my XL HJC FF, but I hear it a lot better now that I got a L HJC FF, which cut a lot of wind noise. I hear it better without earplugs. I wore them before, but haven't had to with new helmet.
wear a half helmet and I do have a tall wind shield , bought the bike used so not sure about any upgrades but have the hk unit and sounds great at any speed and with the right song gets cranked up
What pipes are you running? I have the stock head unit and just added the BOOM speakers and am happy with them. I had 6.5inch 4 ohm speakers that I wasn't really happy with. I can hear my speakers at 80 MPH with Bub TDs.
Have upgraded speakers on my classic and with earplugs, no problem. Without earplugs wind noise and engine noise create a very distorted sound. Only issue with earplugs is you need to turn the sound up and then it can be interesting watching the neighbours as you drive by.
