I bought the smh10 to trial in my own helmet, I've had it on about a month now. I've been using it mainly to listen to music while working and make a few phone calls. There are a whole bunch of options available with the kits, you get the basic module, then you can get all kinds of fitup kits for different styles of helmets (open face vs closed) and then a whole bunch of other options for seperate mics or integrated, long or short boom, hardwired speakers or headphone sockets etc etc... The standard speakers are pretty awful so I bought another kit with the speaker socket with the idea of raping some half decent headphones and integrating them into some muffs. Unit seems pretty robust so far, except for the microphone which doesn't seem to be holding up well to rain and muck. This is a pretty pricey deal, the whole unit (module, install kit, charger etc) was $250, and I bought an extra kit with speaker plug for $50. Add in a helmet ($160) with muffs and clips ($60) and a decent pair of headphones ($100) and you've got $550 sitting on your head which will last maybe a year. I prefer to think of it as $10.58c a week, or $2.11c a day. Less if I work Saturdays.
I'm going to get another for one of my groundies. Ouch.
