This isn't a class action, it's a large binding arbitration case, and so the awards can be individually opted into while being negotiated en masse.

There was a similar case with a well known speaker company, and the payouts for that were several hundred dollars, and there's another one that's ongoing for Steam/Valve along these same lines. The attorney's fees come out of a percentage of the individual award, which can be much higher in these cases.

Or, a bill for costs after you lose.
