Short answer: the Devialet Mania on measured sound quality, the W-King D9 on price. The Devialet Mania ranks #40 of 78 large speakers at $899. The W-King D9 ranks #66 at $71.24, $827.76 cheaper.
What the Devialet Mania offers: Small, nice looking. Watch for: Not very loud. Extremely high price. Bass boosted. Tweeters are not aimed at you and there’s a huge treble rolloff off-axis as compared to the Beoplay P6 in the comparison video. Only 10 hours of battery. Oluv didn’t like the upper mids or treble (mentioned on his Patreon)
What the W-King D9 offers: 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. Watch for: 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.
Buy the Devialet Mania if sound quality is the priority over the price, or the W-King D9 if the price is the priority over sound quality.
The W-King D9 is not a sound-quality pick. It sits near the bottom of the 78 large speakers; there are better options higher up.
Battery life favors the W-King D9: rated for 40 hours against 10 hours for the Devialet Mania.
