Perfect for elise folk that want to speak to their passenger.
So what is it?
The kit consists of two headsets like these

and a little box that runs off a 9v battery
It gives you
1 Ear protection so you no longer end up deaf at the end of the day
2 Music as the box has an input for a iPod which is played over the headsets
3 Ability to talk to your passenger as the box automatically fades the music if playing and switches on the noise cancelling mic and then amplifies your voice so you can speak at normal levels. This works in both directions. One minor downside your can hear your passengers beer burps in perfect clarity
4 Bluetooth module included so you can talk on the phone (never used it so no idea how it works)
5 You can plug in a 2 way radio to talk to others that have a radio
Its a system that is designed for the bikers but works perfectly in a car
On the downside you look like a pleb.
I highly recommend a test drive for anyone that wants it or is curious
