Looks to be a limited time deal ran by the Anker store on Amazon. Comes in Black & Navy.
I have these myself and they have replaced my more expensive Google Buds as my go to daily earbuds. Great sound quality, ANC and exceptional battery life for the price.
These usually hover around $90 if on sale, they may have gone lower before but I think only rarely.

I have this in White and Navy. They are great. Battery back up is good too.
