You’re thinking of Beats. And you’re still wrong because the Beats were knock-offs.

My mistake. Nice catch.

That being said, AirPods use a steel frame construction to get the weight up for the same reason. There's a whole thing with weight in neuromarketing for luxury and luxury-adjacent products. There's fringe benefits acoustically to using it, around resonance mainly, but mostly it's to get weight and influence perception. Same reason as the knock-offs, different mechanism.

Noting that you have no way of knowing that. Not that you’re necessarily wrong. I just read some reviews on the Beats Studio Pros and…the reviewer noted the amount of plastic used in the construction, while complimenting the light weight. Pick a lane, folks.
