Lots of people equate weight with quality. Good for selling them in store, bad for actual use.

I remember a teardown where weights were taped inside. I think it was a beats headphone.

It was Beats. At first it was found in counterfeit Beats, but later the same was found in genuine Beats. And then guess who bought Beats for their exquisite metal weight technology? That's right, it was Apple.

		They bought them for the streaming service that came with it. Not for fake weights in headphones.
