Former Mayor Rudy Giuliani — who caused a social media conniption for wearing his Apple AirPods upside down — “had no idea” there is a wrong way to put them in his ear, he told The Post on Wednesday.

“Sometimes I wear them with the thing pointing up – sometimes I wear them with the thing pointed down,” the 73-year-old said.

The snap, posted Tuesday by Republican strategist Rick Wilson shows him and the former mayor, at LaGuardia Airport. “LGA, crossroads of the world,” Wilson tweeted along with the picture.

The $159 AirPods are typically worn with the tip pointing down towards the mouth of the person wearing them, but in Giuliani’s ears, the bottom of the wireless headphones are facing up.

“I don’t think it’s a very big deal,” Giuliani said.

But the Twitterverse thought otherwise.

“I have literally never seen anyone wear AirPods in a more disturbing way. I didn’t even know that was physically possible,” Twitter user Michael Sagmeister tweeted.

Another Twitter user tweeted: “Someone tell Rudy how air pods work.”

“Are we sure he didn’t get q tips stuck in his ears?” wondered Joel Mendelson.

Levi Gibian wrote: “Rudy Giuliani doesn’t know how to wear apple air pods.”

Giuliani shrugged off the harsh reaction.

“If they’re disappointed, they’re disappointed,” he said, chuckling. “I assure them I can hear the music well.”

Giuliani served as mayor of the Big Apple from 1994 to 2001 and was most recently tapped by President Trump to serve as the nation’s cyber security advisor.
