Short answer: both are discontinued, so this only matters if you are buying used. Used, the Sony XB33 is the better pick: it ranks #77 of 175 medium speakers by sound quality (rated 3.4/5), against #90 (rated 3.2/5) for the JBL Flip Essential. If you want one new, the JBL Flip Essential 3 SE replaces the JBL Flip Essential and is rated 3.6/5 at $113.82.
The Sony XB33 is the longer-running pick. IP67 rated and lightweight (2.4 lb). It is rated for 24 hours of battery against 10 for the JBL Flip Essential. It supports LDAC Bluetooth, which the JBL Flip Essential lacks. It links with other speakers (Party Connect up to 100 speakers), which the JBL Flip Essential cannot. The catch: Not very loud.
The JBL Flip Essential is the lighter choice. A genuinely portable 1 lbs (471 g) speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. At 1 lbs (471 g) it weighs much less than the Sony XB33 at 2.4 lbs (1.1 kg). It keeps a wired aux input, which the Sony XB33 lacks. The catch: Bass is lighter than the JBL Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight.
Buy the Sony XB33 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Flip Essential 3 SE, which replaces the JBL Flip Essential.

JBL Flip Essential: $130 Discontinued eBay
Newer model: the JBL Flip Essential 3 SE, ranked higher, estimated 3.6/5, released Apr 2026. See every JBL Flip Essential generation.
Pros: A genuinely portable 471g speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. It is a simple, no-app option for wired sources, travel and casual listening where its cylindrical shape and modest size are a genuine advantage.
Cons: Bass is lighter than the JBL Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight. Battery life is only a claimed 10 hours, there is no speakerphone, EQ or party mode, and its older Bluetooth 4.1 platform and discontinued status make it a basic used-market choice.
