What is the OUI 10:43:69?

10:43:69 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Soundmax Electronic Limited. It covers every address from 10:43:69:00:00:00 to 10:43:69:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-43-69.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:43:69:00:00:00 that is 10:43:69 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is Soundmax Electronic Limited located?

Soundmax Electronic Limited is listed at Room#1505, Oriental plaza, #1072 JianShe Road SHENZHEN Guangdong CN 518001 in the IEEE OUI registry entry for 10:43:69. This is the address the organization registered with the IEEE, which may differ from its current operating address.
