Short answer: the JBL Flip Essential 3 SE, if you are buying new. The JBL Flip Essential ranks higher than the Sony ULT Field 1 (#90 vs #100 of 175 medium speakers) but is discontinued; its replacement, the JBL Flip Essential 3 SE, is rated 3.6/5 at $113.82 and is still sold new.
The JBL Flip Essential is the lighter option. 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 noticeably less than the Sony ULT Field 1 at 1.4 lbs (650 g). It keeps a wired aux input, which the Sony ULT Field 1 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.
The case for the Sony ULT Field 1: IP67 rated, survives drops and 1m submersion. It supports AAC Bluetooth, which the JBL Flip Essential lacks. It links with other speakers (Party Connect up to 100 speakers), which the JBL Flip Essential cannot. It has an adjustable EQ, which the JBL Flip Essential lacks. Watch for: Upper midrange peak, rolled off treble.
Buy the JBL Flip Essential 3 SE, the replacement for the discontinued JBL Flip Essential; it is rated higher for sound quality than the Sony ULT Field 1.

The Two Speakers In Full
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.
