Short answer: the EarFun Uboom L. It ranks #2 of 182 medium speakers by sound quality, rated 4.6/5, at $49.79; the JBL Flip Essential 2 ranks #80, rated 3.3/5, and costs $85.90, so there is little reason to consider the other one.
The EarFun Uboom L is the better-sounding, longer-running choice. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. It is rated for 16 hours of battery against 10 for the JBL Flip Essential 2. It supports AAC Bluetooth, which the JBL Flip Essential 2 lacks. It keeps a wired aux input, which the JBL Flip Essential 2 lacks. Watch for: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The JBL Flip Essential 2 is the lighter pick. A compact, affordable waterproof speaker that gets fairly loud for its size and connects to two phones at once. At 1.1 lbs (520 g) it weighs noticeably less than the EarFun Uboom L at 1.4 lbs (650 g). The catch: There is no tweeter, and side by side comparisons found it does not sound as good as the JBL Flip 6, with less bass; its bass stops growing above about 70% volume, so turning it up mostly adds loudness, not weight.
Buy the EarFun Uboom L. It is rated higher for sound quality than the JBL Flip Essential 2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
