Best quality bluetooth helmet?

I'm looking to buy a new motorcycle helmet, but I'm unsure which to get just because I'm looking for something very specific. I'm hoping one of you has a good recommendation!

- First, must be a full helmet. Modular or not isn't a big issue, in my opinion.
- Visor must at least be fog resistant. I don't mind wearing my sunglasses but a tinted visor would be nice.
- High quality speakers. I love listening to music and do so through my iPhone. I want to be able to hear the music even if I'm doing highway speeds. This is really where I'm having trouble. I don't require any sort of microphone or whatever. I just want good quality speakers.
- Control buttons are optional.

I'd also prefer black (to match the bike) and a medium size.

I own a Bell Star Carbon Hess. Wow what a nice helmet! Has very good airflow and optional transitions coated face shield that darkens automatically depending on light conditions. It is also coated with an anti fog coating that works better than any thing I have ever used before. My head buffets at speed less with the helmet on than off. It is among the lightest on the market with its carbon fiber construction and yes is available in black both shiny and flat. All that being said you can install a bluetooth system in this helmet. Provisions for speakers and such were engineered into its design. There are no Bluetooth helmets on the market I know of that offer all the features of a Bell Star Carbon. It is pricey, but it is awesome! One of my main reasons for purchasing this helmet was airflow and it sure does flow some air for a full face! All of the other features were just icing on the cake. Check out helmet headsets at motorcyclesuperstore.com and you will see various units that will fit right in the Star. What you will end up with is better than anything else on the market at this time.
