Jenbel - You must have misread my original post. re clothing. I was flying from Glasgow. In early April. Anything less than full arctic gear before mid summer is simply madness.
Regarding sneaking the headphones back on after the cabin check could be a concern, except it was an A321, I was in 8C, the FA approx 2 feet across the aisle in the crew seat at 8D!
And I certainly wouldnt make a complaint about it even if they thought thats what i was going to do.
