The sound even on a 3 or middle setting is more than loud enough to wake us up if the baby cries.

It takes a bit of noise for it to pick up my baby crying

We barely heard our baby crying.

Baby cries, you hear the baby

Coverage and baby cry detection are good

It works as it is supposed to

From the moment I opened it, it had to be always plugged in to work as there is no battery feature (the batteries are defective)

Highly recommend as long as you want a no frills just reliable audio monitor!

We keep it hooked up to the charger throughout the entire night to make sure the battery does not run out and turns it off which keeps it working as we need it to
