Empty Box/partial will be difficult with 5 of them. 

I'd say the SE will most certainly fail.

It's extremely unlikely that the warehouse made a picking error with 5 AirPods. Moreover, the total weight Is around 250 grams, which will register a weight on consignment and confirmed when cross-checked with the carrier's manifest.

At what weight does the weight register on consignment?

It varies between carriers but generally speaking, anything greater than 100 grams.

We've calibrated our shipping scales at work to 50 gram Increments, but even so, It's still difficult to Identify the variance/discrepancy In weight.
