KosherTech is ranked #44 of 48 in the speaker-review source reliability ranking. The ranking weighs measurement quality, repeatability, useful comparisons, disclosure, and editorial independence; it is an assessment of the work used for speaker decisions, not a claim about personal character.
Reliability assessment: The recording chain does not reproduce bass adequately and there is little standardized comparison evidence. Use the videos for product appearance and basic operation, not for judging frequency response or bass extension.

Ranked #71 of 75 in Boombox Size Portable Bluetooth Speakers - Turtlebox Gen 2: $400 Discontinued eBay
Pros: Waterproof and crushproof, loud with punchy bass. 25 hour battery life (6 hours at full volume; 3 hour charge time). USB-C charging and USB-C output charges other devices, an upgrade over the original’s AC power brick. Pairs with a second unit for stereo.
Cons: Sounds basically identical to the original and the Gen 3: each generation mainly added features, not sound quality. They pretty much lie about all their specs and sound horrible in all youtube sound samples. Only 50w (from their indigogo page), will never hit 120db at a reasonable measuring distance. Putting your db meter right against the speaker doesn’t count, 1 meter distance is the standard. Barely any bass. Rattles at high volume. Looking at it, it appears to be a generic car 2-way 6x9 speaker in a plastic box. Discontinued.

Ranked #72 of 75 in Boombox Size Portable Bluetooth Speakers - Turtlebox: $329 Discontinued Amazon eBay
Pros: Waterproof and crushproof, loud with punchy bass. 25 hour battery life (6 hours at full volume). Pairs with a second unit for stereo.
Cons: Sounds basically identical to the later Gen 2 and Gen 3: each generation mainly added features, not sound quality. They pretty much lie about all their specs and sound horrible in all youtube sound samples. Only 50w (from their indigogo page), will never hit 120db at a reasonable measuring distance. Putting your db meter right against the speaker doesn’t count, 1 meter distance is the standard. Barely any bass. Rattles at high volume. Uses an external AC power brick to charge, before USB-C was added on the Gen 2. Looking at it, it appears to be a generic car 2-way 6x9 speaker in a plastic box. Discontinued.
