I check this info too often, but according to AC, in J, "After boarding, a travel essentials bag will be distributed, containing a Customer Care Kit (with mask, hand sanitizer, water bottle, and a snack), want les essentiels amenity kit, and a noise cancelling headset for use during your flight."

Personally I think this is the biggest development on the kit recently - the earbuds are hardly useable and I actually don't find the headset all that bad.
