BLUECOM — 2 prefixes (MA-L)

A MAC address starting with B8:AD:3E or B8:F8:BE belongs to BLUECOM Co., Ltd., a South Korean Bluetooth-audio hardware maker, typically seen on Bluetooth headsets, earbuds, and related wireless-audio accessories. Both blocks are registered in the IEEE MA-L registry to the same organization name and street address.

BLUECOM is a real, identifiable company rather than a bare shell registration. It is publicly traded on KOSDAQ under ticker 033560, and an FCC equipment-authorization filing (grantee code U3W, FCC ID U3WFLEX800, a Bluetooth NeckBand Headset) is registered to the identical Incheon street address that appears in the IEEE OUI record.

Per third-party company profiles, BLUECOM traces to 1990 as Sambu Communics Co., Ltd., renamed Bluecom Co., Ltd. in December 2006. It ships consumer Bluetooth audio under its own "EX-FIT" line and also does ODM manufacturing of TWS earbuds, neckband headsets, Bluetooth modules, and speaker/receiver components for other brands. The company's own site could not be reached (TLS certificate error), so these product claims rest on third-party sourcing rather than a first-party source.

No CVE, malware, or vulnerability advisory naming BLUECOM specifically was found as of an August 2026 search. A separate 2025 Bluetooth-chipset vulnerability line (Airoha SoC flaws) affects other headphone brands — Sony, Bose, JBL, Marshall, BeyerDynamic — with no source tying BLUECOM hardware to that issue.
