Bluetooth hands free on helmets..

I saw what looked like a bluetooth hands free stuck outside of the helmet of a rider…I need a good handfree but which does not break the bank. any advice.

I’ve got the scala rider (teamset version) and for the money its good. Paid £120, but the single version is around £70.

you will be pushed to find a good one cheap.
we do a flip up lid that you can fit a blue tooth set to but the lid is £149.99 without discount and the blue tooth set is also £149.99.
