Short answer: the Marshall Kilburn III. It ranks #41 of 97 large speakers by sound quality, rated 3.8/5, at $379.99; the Devialet Mania ranks #49, rated 3.6/5, and costs $899, so there is little reason to consider the other one.
The Marshall Kilburn III is the longer-running choice. Spacious soundstage with broad stereo dispersion from Marshall’s True Stereophonic multi-driver layout, delivering warm, room-filling sound with 45Hz bass extension. It is rated for 50 hours of battery against 10 for the Devialet Mania. It supports AAC Bluetooth, which the Devialet Mania lacks. It links with other speakers (Auracast), which the Devialet Mania cannot. The catch: Noticeable dips in the midrange compromise frequency response neutrality, making vocals and acoustic instruments sound somewhat recessed or muffled compared to more linear competitors like the JBL Xtreme 4 unless the bass dial is dialed back.
Why pick the Devialet Mania: Small, nice looking. The catch: Not very loud.
Buy the Marshall Kilburn III. It is rated higher for sound quality than the Devialet Mania and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Marshall Kilburn III: $379.99 Amazon eBay
Older model: the Marshall Kilburn II (ranked lower, rated 3.8/5).
Pros: Spacious soundstage with broad stereo dispersion from Marshall’s True Stereophonic multi-driver layout, delivering warm, room-filling sound with 45Hz bass extension. Independent physical bass and treble dials allow quick tonal adjustments on the fly, backed by app-based EQ and placement compensation. Battery life is outstanding at up to 50+ hours with USB-C power-bank charging, IP54 splash resistance, 3.5mm aux input, and Bluetooth 5.3 with Auracast broadcast support. Measured bass extension of 45Hz (-10dB).
Cons: Noticeable dips in the midrange compromise frequency response neutrality, making vocals and acoustic instruments sound somewhat recessed or muffled compared to more linear competitors like the JBL Xtreme 4 unless the bass dial is dialed back. Kilburn II retains slightly punchier perceived loudness at maximum volume due to a more aggressive V-shaped contour. At 2.85 kg with only IP54 splash resistance, it is heavy and cannot withstand water immersion. Lacks a built-in microphone and LDAC codec support.

Devialet Mania: $899.00 Amazon eBay
Pros: Small, nice looking. Measured bass extension of 47Hz (-10dB).
Cons: 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)
