Skullcandy holds eight MA-L blocks, all registered to "Skullcandy" in Park City, Utah, US: 5C:44:3E, 98:67:2E, D0:8A:55, 88:08:94, 38:F3:2E, 60:C5:E6, 8C:0D:D9, and E8:8F:16. The blocks split across two registry addresses — four cite 6301 N. Landmark Dr. and four cite 1441 Ute Blvd., both in Park City 84098 — consistent with a corporate address change, though IEEE publishes no assignment dates so the ordering of those addresses cannot be dated from the registry. Skullcandy is a consumer audio brand founded in 2003 (Rick Alden and Cris Williams), publicly traded from 2011 until Mill Road Capital took it private again in October 2016. Its hardware is Bluetooth headphones, true-wireless earbuds, and Bluetooth speakers — peripherals, not network nodes. For triage, a Skullcandy OUI on the wire identifies a paired audio accessory, not a router, server, or IoT sensor, and not a network intrusion. Unlike a chipset OUI, the brand assigns these blocks to its own finished products, so a Skullcandy prefix reliably maps to a Skullcandy-branded device — though, as with all Wi-Fi/BT gear, MAC randomization on the connecting host (phone/laptop) is a separate matter and does not change the vendor mapping of the accessory's own globally-administered MAC.
- IEEE assignment
- 8 prefixes → "Skullcandy", registered Park City, UT, US [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)
- Registry / block size
- MA-L (24-bit OUI); 8 blocks (~134M addresses) [Confirmed] — enrichment/registries/oui.csv; corroborated by https://maclookup.app/vendors/skullcandy
- Verified prefixes (all MA-L, Skullcandy)
- 5C:44:3E, 98:67:2E, D0:8A:55, 88:08:94, 38:F3:2E, 60:C5:E6, 8C:0D:D9, E8:8F:16 [Confirmed] — enrichment/registries/oui.csv
- Registry addresses
- 6301 N. Landmark Dr., Park City, UT 84098, US (5C:44:3E / 98:67:2E / 38:F3:2E / 60:C5:E6) and 1441 Ute Blvd., Park City, UT 84098, US (D0:8A:55 / 88:08:94 / 8C:0D:D9 / E8:8F:16) [Confirmed] — enrichment/registries/oui.csv. Two addresses are consistent with a company move; IEEE publishes no dates, so which came first is not datable from the registry.
- HQ / country
- Park City, Utah, US [Confirmed] — enrichment/registries/oui.csv; https://en.wikipedia.org/wiki/Skullcandy
- No IEEE date
- IEEE public OUI data (oui.csv columns: Registry, Assignment, Organization Name, Organization Address) contains NO registration date. Third-party "date registered" values for these blocks (e.g. dates shown on maclookup.app / adminsub.net, ranging ~2013–2025) are database artifacts, not IEEE facts — none is stated here. [Confirmed] — enrichment/registries/oui.csv
- Company status
- active; founded 2003 (Rick Alden, Cris Williams); IPO 2011; taken private by Mill Road Capital Oct 2016 (~$196.9M) [Confirmed] — https://en.wikipedia.org/wiki/Skullcandy
- Device types
- Bluetooth headphones (over-/on-ear), true-wireless earbuds, Bluetooth speakers, gaming headsets — all wireless models use Bluetooth; no networking, IoT, or enterprise gear [Confirmed] — https://www.skullcandy.com, https://en.wikipedia.org/wiki/Skullcandy
- Notable products
- Crusher and Hesh headphone lines; Sesh / Dime / Push earbud lines [Likely] — https://www.skullcandy.com (product-line names from current catalog; line membership may shift with catalog updates)
- Security context
- No Skullcandy-specific CVEs or confirmed vulnerabilities found. Skullcandy is NOT listed among the confirmed-affected vendors for the WhisperPair Google Fast Pair flaw (CVE-2025-36911) or the Airoha SoC "RACE" Bluetooth-audio vulnerabilities (disclosed Dec 2025); both name other audio brands (Sony, JBL, Jabra, Marshall, Bose, etc.). Skullcandy's Fast Pair support status is unconfirmed publicly, so CVE-2025-36911 applicability cannot be asserted either way. Generic Bluetooth proximity risks (bluejacking, bluesnarfing, eavesdropping) apply to all consumer BT audio. [Likely — "not listed" is absence-of-evidence, corroborated across multiple security writeups] — https://www.rescana.com/post/whisperpair-bluetooth-fast-pair-vulnerability-cve-2025-36911-exposes-millions-of-audio-accessories, https://insinuator.net/2025/12/bluetooth-headphone-jacking-full-disclosure-of-airoha-race-vulnerabilities/
- Threat level
- Low — consumer BT audio peripherals are not network nodes and do not traverse IP networks independently; a Skullcandy OUI on a network indicates a paired audio device, not an intrusion. [Confirmed]
- IANA reference
- none — IANA governs IP/port assignments, not IEEE MAC OUI blocks (IANA Reference column stays blank) [Confirmed]
- MA-M / MA-S
- none — no Skullcandy assignments in MA-M (mam.csv) or MA-S (oui36.csv) [Confirmed] — enrichment/registries/mam.csv, enrichment/registries/oui36.csv
- Analyst note
- A Skullcandy OUI maps reliably to a Skullcandy-branded audio accessory (the brand assigns these blocks to its own finished products). Host-side Wi-Fi MAC randomization is a separate concern and does not affect this vendor mapping.
