DJ claim

Are in-ear monitors safer than wedges?

Safer in principle because they isolate, and only if the isolation is not spent on more level.

What the evidence actually shows

Isolation allows a lower absolute level for the same signal-to-noise ratio, and studies of monitoring practice find lower exposure where in-ears are used with level management. [1]

There is real evidence here and it points one way, but it rests on fewer or smaller trials than the confident version of this claim implies. Treat it as a reasonable bet rather than a fact.

In-ear monitors is graded "promising". These claims are marketed with roughly equal confidence; this is the same list sorted by what actually supports them. Grading: our reading of the cited literature, not a formal GRADE assessment.

The catch

Without level limiting, people frequently use the extra headroom to go louder. The equipment enables a safer choice; it does not make it.

Are in-ear monitors safer than wedges?
Promising but unsettled. Isolation allows a lower absolute level for the same signal-to-noise ratio, and studies of monitoring practice find lower exposure where in-ears are used with level management.
What is the main misunderstanding about in-ear monitors?
Without level limiting, people frequently use the extra headroom to go louder. The equipment enables a safer choice; it does not make it.
How confident should I be in this?

What we are not claiming

This is general information drawn from published research, not advice about you specifically. Effect sizes in free-living people are usually smaller than headlines suggest, and an average across a trial population may not describe you.
