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 Sony ULT Field 5 ranks #59 of 120 large speakers by sound quality at $348.
The JBL Charge 5 Wifi is the lighter pick. 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 much less than the Sony ULT Field 5 at 7.3 lbs (3.3 kg). Watch for: Shouty upper mids.
What the Sony ULT Field 5 does well: A tough, waterproof party speaker with loud, bass focused output, an aux input, a power bank and a long battery. It supports LDAC Bluetooth, which the JBL Charge 5 Wifi lacks. It keeps a wired aux input, which the JBL Charge 5 Wifi lacks. It links with other speakers (Party Connect up to 100 speakers), which the JBL Charge 5 Wifi cannot. Watch for: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth.
Buy the JBL Charge 5 Wifi at $139.95 if you want a medium speaker. Buy the Sony ULT Field 5 at $348 if you want a large speaker instead.
