This looks like an upgrade of the Soundcore 2.
The manual says “Soundcore Select” - we saw that product name before what what got released seemed to have been called Soundcore 2.
Usual caveats: FCC listings are of alpha/beta products, final can be and often are different, specifications which do not affect the EM radiation do not need to go back through FCC, so often the likes of battery size, speaker performance, etc can change. The product also may not be released if beta customer feedback causes need for a major change.
