The Isotunes uses a series of beeps while adjusting the volume to indicate change. It beeps twice together once it meets a limit. Maximum volume depends on how well the earbud tip seals and how deeply it is inserted. Maximum volume on mine was well below the pain threshold but loud enough to enjoy.

As I understand it, the tips work just like earplugs - in this case the PRO version gives you an average 27 decibels of noise reduction - as good as many earplugs.
