Is this a solution for a real problem or was it done 'because we can.'
The Dainese Airstream Course Bluetooth helmet has phone and intercom connectivity built in, and I've been riding with it for about 200 miles.
Dainese is an Italian company that provides "Head-to-toe protection for people who engage in dynamic sports," including scooters/motorcycles, snow sports, mountain biking, and water sports. They're also developing a motorcyclists' airbag vest called the D-Air that works like a car airbag, but you wear it.
My challenges with helmet selection have been a fat head, which is always too hot even when wearing just a hat. I initially wanted a helmet with a flip up chin, but learned that you're not supposed to ride with the chin piece in the 'up,' position, because the helmet can pop off easily, the rest of the helmet requires the structure for shape retention during impact, and the aerodynamics are poor.
I was comfortable in a Dainese L, which I though was amazing, because almost every helmet I tried at the store that fit, was an XL. I like my chin, occasionally use my brain (reason for the heat?) so while there is an open face version with a cool looking fighter pilot microphone, I chose the full-face version.
The venting system works great at keeping my head cool on the couple 95-degree days we've had so far. There are two moveable plastic sliders that open airflow to your face. One directs airflow to the top of your head, which then exits just above the neck, while the other provides fresh air to your face. See the photos for open and closed images. These sliders are a little tough with gloves on.
The other neat feature is the visor lock. The visor lock allows the visor to be locked open about an eighth of an inch for ventilation. The lever for locking it open is on the left and can easily be manipulated with gloves.
The helmet has very little wind noise at cruising speed, is reasonably light, and I think it is pretty aerodynamic because my neck hasn't been wrenched off while checking traffic behind while moving.
I'm waiting for my dealer to receive the tinted visors, so no opinions there. The only color it is available is 'Soft Titanium,' which is a flat gray, and may blend into the environment a little too much. The venting controls are a little too close together for a Helmet Halo, but it works anyways.
On to the Bluetooth features!
I'm a gadget guy when they work. If they don't, I threaten to eliminate every similar piece of equipment within reach, and then realize something isn't plugged in or turned on. I also almost never RTFM.
I don't like my Bluetooth headset, too much of a Star Trek/Enders Game look (reason for the blue color?) and 'I'm so important I can't miss a call,' effect for me. My current Bluetooth headset is one that pops up as one suggested for in helmet use, and I can't imagine having it between my skull and helmet; it falls off just walking around, so why chance loosing the thing at 60 mph?
Having the option of listening to my wife scream lookout or tell me to slow down, should she ever agree to go for a ride, could be cool. We bought two.
There is a built in microphone and speakers by your ears. The microphone doesn't interfere with cruisin' karaoke or sticking your tongue out at little kids who make faces, although they can't see your response. The speakers are loud enough for most conditions, and there is volume control.
We've tried the intercom in the house while vacuuming - for effect, and they worked great until the doorbell rang, and one of the neighbors looked in. The Bluetooth feature works between helmets with or without a phone.
Two or more of the Dainese Bluetooth helmets can connect, so on a group ride, riders within about 30 feet can chat. Getting the helmets into conversation mode was very easy, with the usual hold the button down trick. The battery recharges in about 5 hours, and is supposed to last up to twelve hours. The charger is very much like the one for your cell phone.
Answering a call can be set up one of two ways, automatic answer, or push the button on the helmet. I think there is a way to use voice dial, should your phone have it. While I do not intend to be on the phone not watching for SUV drivers who are also on the phone not watching for scooter riders, having that as an option was too cool to pass up.
I've left messages on the home phone to check the quality and it was quite good, and my speech was intelligible. The sound quality is better than that friend who only calls from the big game or while driving with the windows down trying to set a new land speed record.
Considering the price of a good helmet, and one of the add- on intercom systems and figuring out where to put it, or the clunky-ness of FRS radios or keeping a piece of string taught between two helmets, a Bluetooth helmet might be for you.
No I haven't tried to Bluetooth my iPod into the helmet, not sure that would be safe, and as far as I can tell, without RTFM, it won't work.
The helmet comes with a great helmet storage bag, lots of instructions, a chin area wind deflector (so there isn't a rush of air from below?), and some other stuff I haven't bothered to look at.
How expensive are they you ask? Silly expensive I answer. MSRP is around $650, we bought ours when we dropped the cash for the GTS, so we got a smokin' deal that I promised not to reveal. I'd expect them to retail without a bike purchase around $500. All of the photos are taken of my wife's helmet, I couldn't be bothered to clean bug guts on mine.
