Short answer: the LG Xboom Bounce. It ranks #33 of 115 large speakers by sound quality, rated 4.0/5, at $103.17. The W-King D9 ranks #93, rated 2.5/5, at $89.98, $13.19 cheaper, which does not close the gap in sound quality.
The W-King D9 is the deeper-bass, longer-running pick. A compact, punchy boombox with a very long rated battery, water resistance, and power bank output for casual outdoor use. Its bass reaches about 47Hz before falling 10dB, against 54Hz for the LG Xboom Bounce. It is rated for 40 hours of battery against 30 for the LG Xboom Bounce. Watch for: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
The LG Xboom Bounce is the better-sounding, lighter pick. A tough, waterproof speaker that survives drops and extreme temperatures, with a long battery and multipoint pairing. At 2.9 lbs (1.32 kg) it weighs noticeably less than the W-King D9 at 4.4 lbs (2 kg). It supports AAC Bluetooth, which the W-King D9 lacks. It links with other speakers (Auracast), which the W-King D9 cannot. Watch for: Bass extension not as deep as the top speakers.
Buy the LG Xboom Bounce. It is rated higher for sound quality, and the $13.19 saving on the W-King D9 is not enough to make up the difference.
