Short answer: the Bogasing G4. Both are rated 4.0/5 for sound quality (#27 and #31 of 177 medium speakers), and the Bogasing G4 costs $42.49 against $118.99 for the Soundcore Boom 3i, and with sound quality even, the cheaper one is the better buy.
The case for the Soundcore Boom 3i: A warm, punchy waterproof speaker that sounds great and is a strong value. It supports AAC Bluetooth, which the Bogasing G4 lacks. It has an adjustable EQ, which the Bogasing G4 lacks. The tradeoff: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The Bogasing G4 is the longer-running choice. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. It is rated for 24 hours of battery against 16 for the Soundcore Boom 3i. It keeps a wired aux input, which the Soundcore Boom 3i lacks. It plays in stereo from a single unit, unlike the Soundcore Boom 3i. The tradeoff: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
Buy the Bogasing G4. Both are rated the same for sound quality, and it costs $76.50 less than the Soundcore Boom 3i.
