Short answer: the JBL Xtreme 4 on measured sound quality, the W-King D8 on price. The JBL Xtreme 4 ranks #44 of 105 large speakers, rated 3.8/5, at $309.95. The W-King D8 ranks #57, rated 3.5/5, at $69.99, $239.96 cheaper.
The JBL Xtreme 4 is the louder option. A rugged 4.6 lbs (2.1 kg) portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Alan Ross Reviews measured it at 106dB at full volume, against 101dB for the W-King D8. It links with other speakers (Auracast), which the W-King D8 cannot. It has an adjustable EQ, which the W-King D8 lacks. The tradeoff: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume.
The case for the W-King D8: Claimed 24 hours (manufacturer specified) battery life, ipx7 protection, up to 101db and stereo playback make its feature set practical for its intended room or portable use. It keeps a wired aux input, which the JBL Xtreme 4 lacks.
Buy the JBL Xtreme 4 when sound quality outweighs the price for you, and the W-King D8 when the price outweighs sound quality instead.

JBL Xtreme 4: $309.95 Amazon $309.95 B&H Photo Video $309.95 eBay
Newer model: the JBL Xtreme 5, ranked higher, rated 4.6/5, released Apr 2026. It adds USB audio input, AAC and LC3, but drops the built-in mic. Water resistance goes from IP67 to IP68.
Older models: the JBL Xtreme 3 (ranked higher, rated 4.3/5), the JBL Xtreme 2 (ranked lower, rated 3.4/5) and the JBL Xtreme (ranked lower, rated 3.2/5). See every JBL Xtreme generation.
Pros: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Independent reviews find the midrange detailed and the sound clear, punchy and refined for outdoor use; it also reaches a strong 106dB maximum level and has excellent real-world battery life.
Cons: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume. The front-facing layout has only modest off-axis consistency, Bluetooth latency is high for video, and the default balance benefits from EQ adjustment. There is no aux input, so wired sources are not supported. Out of the box it leans bass-boosted, with a dip between the upper bass and midrange that EQ cannot fix, and it pushes the upper mids and treble at high volume. It is also expensive.
