Short answer: the JBL Xtreme 5, if you are buying new. The JBL Xtreme ranks higher than the W-King D9 (#72 vs #91 of 105 large speakers) but is discontinued; its replacement, the JBL Xtreme 5, is rated 4.6/5 at $349.99 and is still sold new.

The JBL Xtreme is the better-sounding pick. 15 hour battery. It links with other speakers (Connect), which the W-King D9 cannot. Watch for: Issues with bass distortion at high volumes.
The W-King D9 is the louder, longer-running choice. A compact 4.4 lbs (2 kg) boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Alan Ross Reviews measured it at 106dB at full volume, against 96dB for the JBL Xtreme. It is rated for 40 hours of battery against 15 for the JBL Xtreme. The catch: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
Buy the JBL Xtreme 5, the replacement for the discontinued JBL Xtreme; it is rated higher for sound quality than the W-King D9.

W-King D9: $71.24 Amazon $71.24 eBay
Pros: A compact 2kg boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Long-term owners praise its loud, punchy character and useful indoor/outdoor voicing for casual outdoor listening. Measured bass extension of 47Hz (-10dB).
Cons: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume. There is no app or adjustable EQ, and its bass does not reach as deep as larger rivals, so it is better suited to energetic background music than neutral listening.
