1MORE — 5 prefixes (4x MA-L + 1x MA-M)
Summary
- // what this is
- 1MORE is registered to MAC prefix
18:95:52and 4 more in the IEEE OUI database. When a device's MAC address begins with18:95:52, that block was registered by 1MORE — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- 1MORE is an identifiable operating consumer-audio company with multiple OUI assignments and clear product context (Sonoflow, ComfoBuds Z, historic Xiaomi Piston OEM work) -- not a bare single-OUI shell registration.
About this vendor.
A MAC address beginning with one of 1MORE's five registered prefixes — 18:95:52, 6C:CE:44, 9C:97:89, 78:A7:EB, or 28:F5:37:8/28 — belongs to 1MORE, a Shenzhen-based consumer audio company, and typically shows up on Bluetooth or wired earbuds and headphones rather than networking gear.
1MORE holds four 24-bit MA-L blocks and one 28-bit MA-M block, all registered to the same Tianliao Building facility in Nanshan, Shenzhen. Five separate assignments for one brand is consistent with distinct Bluetooth radio/chip product lines across several headphone generations, not a red flag.
Founded in 2013 by former Foxconn executives with early investment from Xiaomi, 1MORE built its early business making OEM/ODM earphones (including the Xiaomi Piston line) before growing an independent retail brand — 1MORE Sonoflow and ComfoBuds Z are current wireless models. The company later added a San Diego, CA office alongside its Shenzhen base.
No security incidents, CVEs, or abuse reports turned up for the brand or these OUI ranges in this pass. That is an absence of adverse findings from a light web check, not a clearance from a dedicated threat-intel review — treat it as Unknown rather than clean.

- No IEEE registration dates
- the IEEE MA-L registry/mam.csv/oui36.csv schema carries no date field for any of the 5 assignments [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry
- Third-party date caveat
- maclookup.app lists per-prefix scrape dates (e.g. 18:95:52=2020-04-25, 28:F5:37:8/28=2017-04-22); these are database artifacts, not IEEE facts, and are excluded from the JSON date fields [Likely] — https://maclookup.app/vendors/1more
- Security context
- no adverse findings in a light pass; not a dedicated threat-intel clearance [Unknown]
- Analyst note
- five OUI/CID assignments for one small consumer-electronics brand reflects distinct Bluetooth radio/chip product lines, not a red flag; the two address-string variants are reported verbatim rather than normalized to avoid fabricating a canonical address.
