Short answer: the Bose Soundlink Flex 2nd gen for better sound quality, the Klipsch Groove/Heritage Groove for the lower price. The Bose Soundlink Flex 2nd gen ranks #33 of 136 medium speakers at $159. The Klipsch Groove/Heritage Groove ranks #90 at $89, $70 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 Klipsch Groove/Heritage Groove offers: Pretty balanced sound. Distinctive mid-century design with real wood veneer and a woven grille, unlike most plastic/rubber portables. ~8 hour battery life. Watch for: Not stereo. Bass doesn’t go as deep as others its size. Gets distorted at higher levels. Wouldn’t generally recommend these old speakers as they can’t compete with modern speakers for bass performance and features.
Buy the Bose Soundlink Flex 2nd gen if sound quality matters more than the price. Buy the Klipsch Groove/Heritage Groove if the price matters more than sound quality.
If water resistance matters to you, the Bose Soundlink Flex 2nd gen at IP67 (brief submersion) holds up far better than the Klipsch Groove/Heritage Groove at IPX4 (Groove), none (Heritage Groove) (splashing).
