Looking at the pictures on the website, they look to be about at least twice the size of the most recent airpods pro, and much larger than the very first airpods (which are massive compared to the more recent ones).

I would have compared the weight directly, but PQ website only shows the weight for earbuds+case together (70g), couldn't find the weight of earbuds alone anywhere. Apple's website lists airpods pro 2 at 3g and the case at 50g.
