Narrative:

Immediately after takeoff we noticed a very strong electrical smell in the cabin. All passenger were holding their noses. I called the cockpit -- other cabin flight attendants were also talking to our first officer. We had no smoke and could not tell where the odor originated. It was very strong and did not dissipate. The captain made a PA and we returned to ZZZ without incident. The fire department came on board to check for 'hot spots' but found none. The aircraft went OTS and we returned to jfk on another B767-300. Callback conversation with reporter revealed the following information: the reporter stated the odor was everywhere in the cabin but there was no smoke and nothing hanging in the air. The reporter said the smell was like an overheated iron cord burning up. The reporter stated the flight crew declared an emergency and went back to ZZZ. The reporter said no cause has been released by maintenance nor is any expected.
