I got curious, and did some back of the envelope mathematics / Fermi estimation.
> Analysts estimate Apple sold between 14 million and 16 million AirPods in 2017.[38] In 2018, AirPods were Apple's most popular accessory product, with 35 million units sold.[39][40] 60 million units were sold in 2019.

In 2020, another 114 million units were sold.

Each airpod weights about 4g. But we're counting sales. So, we're counting pairs. And we also have to factor in the plastic charging case which comes in at 38g since that's also included in the package as well. That makes for a grand total of 46g per sale.
By my count, the total weight of all airpods ever sold is about 10.350 metric tonnes (46g * 225 million units).
According to the Ocean Cleanup project, the Great Pacific Garbage Page weighs about 88.000 tonnes.

Also seems to be confirmed here: https://www.nature.com/articles/s41598-018-22939-w
So, all airpods sold between 2017 and end of 2020 make up about... 11.7% of the Great Pacific Garabage Patch.
That's not a number I'd call "negligible". I'm a bit floored and incredulous and not even all too sure of my number work to the point where I've been re-calculating for the past 20 minutes and I'm arriving at the same numbers again and again.
That's just the amount of waste that will need to be disposed of when all units have reached their end of life.
There's also the production process itself which requires resources and produces waste as well. That's not just the molding of plastics and the assembly of circuits. I'm also talking about the extraction, refining,... of natural resources just to produce the half-finished parts that arrive at the plant where the final product is assembled. There's the logistics and transports involved just to move the entire chain. Oh, and the number juggling above is also discounting packaging and wrapping. There's a massive hidden footprint there as well.
