It seems that the volume meter/level on the iphone doesn't really do much to the volume of the AA until the meter/level on the iphone gets above 2/3 of max volume. Is this normal?

Setting the volume at 50%, the volume level of the speaker is very quiet. Then at about 75% the volume level of the device gets to where I would have expected it to be around 50%. Then between 75% and 100% the device volume really jumps. This makes it difficult to find a suitable setting for different rooms.

The entire 0% to just below 40% iOS volume level should really be between 0% and 10% or so.

If that makes sense. Kinda hard to explain without hearing it.
