Position then ... I ended up mounting a different mic with a flat clip , up on the brow piece of the helmet .. It's fine for visor down, fades pretty quick when visor goes up tho ...
And how noisy is your bike? ... Aftermarket loud exhaust mods? ... Usually has to be damn loud to get over the voice inside the helmet ..
With mic behind the cheek pads.... Not BEHIND and tucked right away ... Outside sound would transmit more I think .... Still gotta leave the mic head sticking out
Helmet a good fit? .... Not loose and flogged out neck foam pieces letting exterior noise in more?
