For most standard open-plan offices (40–60 dB ambient): both Class A and Class B provide guaranteed speech privacy. If your priorities include the highest available acoustic performance, regulated industry confidentiality compliance, or quieter-than-average environments, Class A is the appropriate specification. If cost efficiency and pod mobility are the primary considerations and the office is a standard noise environment, Class B may be appropriate. HIGHKA pods’ Class A certification means they address both contexts without compromise.
