After months of hemming and hawing, I went out today and picked up a Cardo Systems Scala Rider G9 Bluetooth system. I picked it up this afternoon from Cycle Gear, and, while I haven’t had a chance to ride anywhere with it, I did get it partially charged, installed on my helmet, and played around with it a bit. So far the sound seems loud and clear, it was relatively easy to install on my Shark Evoline2 helmet, and I can control my iTunes music, make phone calls, etc. So it works sitting in my living room. The buttons are chunky, and easy to use with gloves. It’s also supposedly waterproof and dustproof. The volume is supposed to increase and decrease with your speed, but I won’t know about that until tomorrow.
It seems OK so far, though, so I’ll probably have a full review up in a day or two.
