The SMH10 can save volume levels of previously connected profiles. This means that phone volume (HSP/HFP), music volume (A2DP), and intercom volumes will be saved separately and return to its own saved volume level whenever associated profile is reconnected.Profile volume adjustment is only affected during the use of its specific profile. However, when changing volume during standby mode, then volume change applies to all profiles. Alert tones like low battery warning and connection tones can only be adjusted in standby mode.Easy Installation for Most HelmetsThe SMH10 will fit onto various types of helmets. The standard clamp, included in default packaging, will fit onto most helmets. For installations which may require extra wire length, ear buds instead of speakers, and wire microphone instead of boom microphone, Sena offers different types of clamps as an additional accessory (sold separately) to allow various installations and user preferences.
