KosherTech is ranked #45 of 49 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.
