Short answer: the EarFun Uboom L. It ranks #2 of 182 medium speakers by sound quality (rated 4.6/5) at $49.79 and is still sold new; the JBL Flip 5 ranks #79 (rated 3.3/5) and is discontinued, so it is only an option used. The JBL Flip 5’s replacement, the JBL Flip 7, is rated 4.2/5 at $149.95.
The EarFun Uboom L is the better-sounding, louder choice. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. Alan Ross Reviews measured it at 103dB at full volume, against 92dB for the JBL Flip 5. It is rated for 16 hours of battery against 12 for the JBL Flip 5. It supports AAC Bluetooth, which the JBL Flip 5 lacks. The catch: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The case for the JBL Flip 5: A compact, light waterproof speaker with a carry strap and USB-C charging. It links with other speakers (PartyBoost up to 100 speakers), which the EarFun Uboom L cannot. The catch: Boosted upper bass.
Buy the EarFun Uboom L. It is rated higher for sound quality; the JBL Flip 5 is no longer sold new.
