Exact Sennheiser HDB 630. Exact Sennheiser HDB 630 is already recognised and connected in its supported Smart Control app. You need the installed headset version for support, no update/download/transfer is active or pending, and you can inspect status without starting one.

Connection scope: Bluetooth. Symptom: I need to check firmware update requirements.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
