Overall the SC1 is a good Bluetooth device. But, is it worth £284.99? My honest answer is...
C4
Schuberth C4 Helmet Review
Review of the new Schubert C4. Overall, the Schuberth C4 is a brilliant helmet. It is expensive but worth the money. Something to consider is that Schuberth will give you 5 years warranty which adds extra value to it.
