Black Friday is Friday, November 27, 2026. Amazon’s Black Friday deals run November 19–30, through Cyber Monday, from 12:01 a.m. PT (3:01 a.m. ET) on November 19. , Amazon lists Dolphin Bluetooth Party Speaker at $249.99, with no deal badge.
Cheaper in Speakers, and what changes
Things of the same kind for at least 10% less than $249.99, with the attributes the retailers describe differently. Their words, not our judgement: we compare listings, we do not test products.
IPX7 means a speaker survives being submerged 1 meter deep for up to 30 minutes, and IP67 adds dust resistance; IPX4 means protected from water sprays, with no claim about being submerged, the X meaning dust was not tested.
Battery hours on a listing are the maker’s own figure: Consumer Reports, for one, gives them as claimed by the maker.
