JBL Flip (Flip 6 / Flip 7)

What matters in a portable speaker
Water and dust resistance: IP67 means the speaker survives a dunk in water and sand at the beach. All three picks meet it.
Size versus sound: bigger speakers move more air and play more bass. If it rides in a backpack, smaller wins; if it sits on the patio table, go bigger.
Battery: all three last a full day out of the house at normal volume. Playing at maximum volume shortens that a lot.
Our verdict
Pick the JBL Flip for the biggest sound and bass. Pick the Bose SoundLink Flex for clear, natural sound and a rugged build. Pick the UE Wonderboom for the smallest, toughest speaker at the lowest price.
