I don’t think this is related to Flaaffy, it doesn’t look like it fits the description.
The metal bits and the random shapes of dark plastic seem encased in a plastic cover, to me indicating that they are part of a carrying/charging case. Which leaves the white parts as independent components.
The holes in the white component on the right look pretty deep, possibly meaning that they aren’t just aesthetically pleasing details, but actually an input/output source. The grey mesh covered in transparent fabric also looks interesting - is that a piece of fabric?
Anyways, my guess is that Nothing is teasing an audio related product, something like a pair of open ear headphones.
