Short answer: the JBL Authentics 300, since the Yeahbox Sonic Boom Max 3’s specs are manufacturer-claimed. The Yeahbox claims 200W RMS (300W peak) from a true 3-way, 5-driver array, but it is a budget import brand with limited independent testing. The Authentics 300 integrates Amazon Alexa and Google Assistant simultaneously, though it sounds narrow and its bass is not as deep as others.
Buy the JBL Authentics 300. It is rated higher for sound quality, and the $70.96 you would save on the Yeahbox Sonic Boom Max 3 does not close the gap.
Water resistance is not close: the Yeahbox Sonic Boom Max 3 is rated at IPX6 (powerful water jets), well ahead of the JBL Authentics 300 at no water resistance.
