Short answer: the JBL Xtreme 3. It ranks #18 of 120 large speakers by sound quality, rated 4.3/5, at $269.95. The Bogasing S8 Pro Max ranks #24, rated 4.2/5, at $169.99, $99.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the JBL Xtreme 3: A loud, waterproof stereo speaker with deep bass, balanced sound and a power bank for charging devices. The catch: Boosted bass.
The Bogasing S8 Pro Max is the longer-running pick. A three way stereo speaker in an aluminum body with a wide soundstage, punchy detailed sound and clean output at full volume. It is rated for 30 hours of battery against 15 for the JBL Xtreme 3. The tradeoff: Its tuning is bright: the 3D mode pushes the mids and treble hard, can sound sharp or tiring at higher volumes, and sometimes adds an echo effect to vocals.
Buy the JBL Xtreme 3. It is rated higher for sound quality, and saving $99.96 with the Bogasing S8 Pro Max does not make up for the sound-quality gap.
