Short answer: the Brane X on measured sound quality, the W-King D8 on price. The Brane X ranks #4 of 115 large speakers, rated 4.6/5, at $549. The W-King D8 ranks #58, rated 3.5/5, at $79.99, $469.01 cheaper.
The W-King D8 is the longer-running, lighter pick. An affordable stereo boombox with four drivers, waterproofing, and a long battery for backyard and beach playlists. It is rated for 24 hours of battery against 12 for the Brane X. At 5.4 lbs (2.43 kg) it weighs noticeably less than the Brane X at 7.7 lbs (3.5 kg).
The Brane X is the better-sounding, deeper-bass choice. A portable speaker with extraordinarily deep bass for its size, plus Wi-Fi, AirPlay, Alexa and a low latency aux input. Its bass reaches about 31Hz before falling 10dB, against 49Hz for the W-King D8. Alan Ross Reviews measured it at 106dB at full volume, against 101dB for the W-King D8. It supports aptX HD Bluetooth, which the W-King D8 lacks. Watch for: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
Buy the W-King D8 if the price is the priority over sound quality, or the Brane X if sound quality is the priority over the price.
