That looks like a nice helmet. I'm curious, though, do you wear ear plugs? How well can you hear the music/calls with ear plugs?
I don't wear ear plugs. I used to but not anymore. When I got the helmet, found that it was hard to hear music/whatever over the built in speakers. The problem was wind noise.
I got a larger shield (Calsci) and that cut down wind noise a lot! I set the volume to low, non ear damaging level before I ride and even at highway speeds, it is loud enough. If I want to change the volume, just turn the knob on the helmet.
If someone calls, you hear the ring come over the music and see the phone number on the iphone. If you want to answer the phone, you tap the screen and talk. I have found that if you have GPS and Pandora running at the same time, you can't answer phone or make phone call, at least that is how it is on my 4s.If someone texts me, I can use Siri to read me the text.
Even without listening to music, that larger shield is real nice to have. Combined with the bazooka muffler, it makes for a very quiet ride.If you ride with plugs, you won't need them with a larger shield, trust me. I used to travel on a katana 1100 and always used Earos foam plugs, i even used them on my C14 before I got a larger shield.
Tell you what, with helmet speakers turned off, and Iphone in its waterproof case mounted on the tree, I can still hear the Iphone (through its iphone speakers) play while I am doing 50 mph, if that gives you any idea of how much a larger shield helps!
