A range quoted in open ground, between two units
An intercom puts a speaker in each ear pocket, a microphone near the mouth and a control unit on the shell, and connects to a phone, to a pillion or to other riders. The figure printed largest is the range, and it is the one that needs its condition attached: a published range is measured in open ground, between two units, with nothing in between. A line of riders behind a lorry on a dual carriageway is not that, and no maker claims it is. What actually decides whether a group stays connected is the topology. A classic Bluetooth intercom pairs units in a chain, and when one rider drops out the chain has to be rebuilt; a mesh system lets units find each other and repair the network on their own, which is why mesh is worth the difference for a group and worth very little for a rider who only wants navigation in one ear. Then the practical figures. Battery life, quoted for talk time, which is not standby and not music playback. Speaker depth, which decides whether the speakers fit a helmet with shallow ear pockets — the most common fitting problem in the family, and one a specification sheet answers in millimetres. Mounting, clamp or adhesive, and whether the helmet has a recess for either. And whether the unit is still receiving firmware updates, which is what separates a three-year product from a one-year one. We compare published range and its stated conditions, mesh or Bluetooth, supported number of riders, battery life, speaker depth, microphone type, mounting and firmware support.

Nothing written into the text below is a current price. Where an amount appears in a sentence, it is the reading taken on the day that sentence was written; what a shop is asking at this moment loads beside the product itself, and that is the figure to go by.
