Short answer: the Bose Soundlink Flex on measured sound quality, the JBL Charge Essential on price. The Bose Soundlink Flex ranks #34 of 136 medium speakers at $84.99. The JBL Charge Essential ranks #68 at $73.99, $11 cheaper.
What the Bose Soundlink Flex offers: IP67 rated; rugged enough to survive drops from several feet and floats. Around 12 hours of battery at moderate volume. Watch for: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail
What the JBL Charge Essential offers: Doubles as a power bank. IPX7 rated. Supports true wireless stereo pairing with a second Charge Essential. Watch for: Less clarity than the Flip 4, highs rolled off. An overpriced rebranded Charge 3 for people who want stereo sound.
Buy the Bose Soundlink Flex when sound quality outweighs the price for you, and the JBL Charge Essential when the price outweighs sound quality instead.
Battery life favors the JBL Charge Essential: rated for 20 hours against 12 hours for the Bose Soundlink Flex.
