I got a set of bose earbuds and they sound great but not loud enough. Does that sirus have a volume on it ? If so it might be okay. I thought about getting the bose headphones and taking off the head piece and just mounting the ear sections in my helmet . As far as that goes it would be better because for one ear buds are illegal to use in a car or bike , but heaphones/speakers that are built in to a helmet are okay . . I've been wearing a cheaper set of earbuds that have a volume control on the cord ( Koss) and they sound good .
