The Kallsup’s replaceable battery is good for up to nine hours of playtime at 50 percent volume, and it’s rechargeable using a USB-C port. It won’t be nearly as loud as a towering party speaker, but up to 100 Kallsup speakers can be wirelessly connected and synced to fill a larger space with music. However, while Ikea announced white, pink, and lime green color options at CES, on its US online store the Kallsup is currently only available in the white and green options.
