All JetBlue planes have a single, 3.5mm connection for the headphone jack (same as all mobile devices, before some phones started eliminating them)

There has long been 2.5mm TRRS, otherwise none of the mobile phones would have used it. It is actually still used today for balanced outs in high-end mobile media playback devices.

Making the conversation more complex to offset a risk so small as to be irrelevant doesn't really help anyone. The OP is going to be fine on their flight. We all know that. The rest of this discussion is stupid.
I got the 2.5mm TRRS bit incorrect; they did exist but not on smart phones in recent generations. That doesn't change the result OP's initial query.

Show me a consumer "mobile device" (the words used in the initial reply) sold in the past 5ish years that uses a 2.5mm TRRS and that might create a legit risk to the OP.
