Short answer: the JBL Flip Essential 2. It ranks #71 of 150 medium speakers by sound quality (rated 3.3/5); the Boat Stone 350/352/358 ranks #130 (rated 2.3/5).
The case for the JBL Flip Essential 2: Essentially a Flip 5 in a new shell: the same single 44 x 80mm racetrack driver and 20W amplifier, rated down to 65Hz. The tradeoff: There is no tweeter, and side by side comparisons found it does not sound as good as the Flip 6, with less bass; its bass stops growing above about 70% volume, so turning it up mostly adds loudness, not weight.
What the Boat Stone 350/352/358 does well: Long battery life (12 hours), IPX5 water resistant, compact and portable, sturdy build, dual passive radiators. Watch for: Some midrange peaks, treble slightly rolled off.
Buy the JBL Flip Essential 2. It is rated higher for sound quality than the Boat Stone 350/352/358.

The Two Speakers In Full
JBL Flip Essential 2: $85.90 Amazon eBay
Older model: the JBL Flip Essential (ranked lower, rated 3.2/5).
Pros: Essentially a Flip 5 in a new shell: the same single 44 x 80mm racetrack driver and 20W amplifier, rated down to 65Hz. In a side by side loudness test it got louder than the JBL Grip, and listeners comparing it with the Marshall Emberton found it more open sounding and clearer. IPX7 waterproof, 520 g, USB-C charging and Bluetooth 5.1 with two phones connected at once.
Cons: There is no tweeter, and side by side comparisons found it does not sound as good as the Flip 6, with less bass; its bass stops growing above about 70% volume, so turning it up mostly adds loudness, not weight. No app, no EQ, no PartyBoost or stereo pairing, a claimed 10 hours of battery, and IPX7 covers water but not dust.
