Even at maximum level, the sound through BellyBuds' speakers will still reach a baby in the womb at a level lower than the mother's own heartbeat.
Also, please notice the "Pre" and "Post" settings on the volume limiter.
The "Pre"-natal setting has a lower maximum volume level and is sufficient to deliver music safely to a baby in the womb.
Switch to the "Post" -natal setting for a higher maximum level of volume. Use this setting when playing voice messages, soft music, or if using BellyBuds simply as ambient speakers after the baby is born.
Both the "Pre" and "Post" settings ensure a maximum level of sound that is safe for a baby in the womb. As everybody's type is different, we encourage you to play BellyBuds at a level that is ultimately most comfortable for you.
