About this vendor.
The supplied IEEE records assign these prefixes to Shenzhen Horn Audio Co.,Ltd. Its company profile describes acoustic solutions, research, design, and ODM/OEM manufacturing. The supplied evidence does not establish which, if any, devices or products use these prefixes; device and product mappings are Unknown.
The two MA-L assignments match the first 24 bits of an address, leaving 24 suffix bits, or 16,777,216 possible suffix values per prefix. The MA-M assignment matches 28 bits, leaving 20 suffix bits, or 1,048,576 possible values. These are address-space sizes, not counts of devices or shipments.
The first byte is F8, C0, or 84, whose Group and Local bits are both zero in each listed prefix. Those bits are fixed for an exact prefix match; changing either bit creates a different prefix. A match supports registry-assignment identification only, not deployment, traffic prevalence, present ownership, or security status.
