Short answer: the W-King X20. It ranks #28 of 73 boombox speakers by sound quality at $219.98; the JBL Boombox 2 ranks #29 and costs $499.95, so there is not much of a tradeoff to weigh.
What the W-King X20 offers: 200W RMS output with 330W peak power, 112dB max volume, exceptional 24-hour battery life with power bank, IPX6 waterproof, EQ with app control and button modes, 7.5-inch subwoofer, Bluetooth 5.3, dual pairing, MicroSD and USB playback, AUX input, TWS stereo mode with 240W combined Watch for: Rising frequency response but upper treble rolled off, 700hz and 1.2khz peaks
What the JBL Boombox 2 offers: 24 hour battery life (default volume); 20+ hours even at 60% volume. IPX7 rated. Doubles as a power bank. Bluetooth 5.1 with PartyBoost (up to 100 speakers). Reaches 101dB. Watch for: Somewhat bass heavy and boomy.
Buy the W-King X20. It ranks higher for sound quality than the JBL Boombox 2 and costs less, so there is no real case for the other one.
