These are not really the same size class, and that is the honest framing here. The Devialet Mania ranks #40 of 78 large speakers by sound quality at $899; the JBL Authentics 300 ranks #32 of 75 boombox speakers by sound quality at $299.95.
The case for the Devialet Mania: Small, nice looking. The tradeoff: Not very loud.
The case for the JBL Authentics 300: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). The tradeoff: Narrow sounding, bass not as deep as others.
Buy the Devialet Mania at $899 for a large speaker, or the JBL Authentics 300 at $299.95 for a boombox speaker instead.
Water resistance is not close: the Devialet Mania is rated at IPX4 (splashing), well ahead of the JBL Authentics 300 at no water resistance.

The Two Speakers In Full
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)
