Shanghai Mountain View Silicon (MVSilicon) is an active Chinese fabless Bluetooth-audio SoC maker registered with the IEEE as "Shanghai Mountain View Silicon" at Suite 4C, Building 3, 1238 Zhangjiang Rd., Pudong, Shanghai, China. Its silicon goes into TWS earbuds, Bluetooth speakers, audio receivers, and smart-audio devices. Budget BT-audio SoCs may have their Bluetooth device addresses allocated by the OEM brand or randomized rather than drawn from the chipmaker's registered block. For triage, a TWS earbud or BT speaker built on MVSilicon silicon may show the end-brand's or a randomized BT address — the MVSilicon OUI (1C:2C:E0) should be checked in context.
