The safety claim, checked
'Volume limited' is not a regulated term. Independent testing has repeatedly found products advertising an 85dB ceiling that exceed it substantially, particularly when connected by cable rather than Bluetooth, or when a child turns up the source device as well as the headphones.
The bottom line
Buy the Puro. If flights are the main use and the budget is tighter, the JBL is a reasonable trade with a caveat you now know about.
