These sit in different size classes, so this is not a straight ranking comparison. The JBL Charge 5 Wifi ranks #29 of 179 medium speakers by sound quality at $139.95; the Marshall Stockwell III ranks #84 of 120 large speakers by sound quality at $249.99.
The JBL Charge 5 Wifi is the lighter, tougher choice. A rugged waterproof speaker with punchy, warm sound plus Wi-Fi streaming over AirPlay and Chromecast, long battery life and a phone charging port. At 2.2 lbs (1 kg) it weighs noticeably less than the Marshall Stockwell III at 2.9 lbs (1.3 kg). It is rated IP67 against IP55 for the Marshall Stockwell III. The catch: Shouty upper mids.
The Marshall Stockwell III is the longer-running option. A stylish, rugged speaker with a very long battery you can swap yourself, a detailed app EQ, and power bank charging. It is rated for 40 hours of battery against 20 for the JBL Charge 5 Wifi. It keeps a wired aux input, which the JBL Charge 5 Wifi lacks. The tradeoff: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
Buy the JBL Charge 5 Wifi ($139.95) for a medium speaker; the Marshall Stockwell III ($249.99) suits a large speaker instead.
