I have invested in these and can say after too many years on bikes that its the muts nuts. helmet is a little noisy but no too bad, the sun visor does mist up a bit or for me being a 365 days a year rider it has over the winter. the blue tooth is fantastic great sound easy to use and syncs to my iphone which i use for music satnav etc no prob;ems costly but worth every penny to me if not the mrs lol
