Short answer: the Bose Soundlink Flex 2nd gen on measured sound quality, the Tribit Xsound Surf on price. The Bose Soundlink Flex 2nd gen ranks #33 of 136 medium speakers at $159. The Tribit Xsound Surf ranks #79 at $26, $133 cheaper.
What the Bose Soundlink Flex 2nd gen offers: Pretty much identical sounding to the 1st gen Watch for: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail. Self drains the battery about 10% a week.
What the Tribit Xsound Surf offers: Rugged rubberized frame with a metal grille. About 20% louder than the XSound Go at the same volume. IPX7 rated, USB-C charging, and pairs with a second Surf for stereo. Watch for: Bass doesn’t go as deep as others, strange midrange peaks
Buy the Bose Soundlink Flex 2nd gen when sound quality outweighs the price for you, and the Tribit Xsound Surf when the price outweighs sound quality instead.
