Sennheiser HDB 630 — select a paired source in Connections. Follow the exact-model instructions and confirm the result.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Exact Sennheiser HDB 630 with a Bluetooth source. The desired source is already paired. The app BLE connection is distinct from the selected audio source. Confirm the first source currently shows an active headphone connection before continuing; a saved pairing entry alone is insufficient. Reversible checks only; no factory reset or pairing-list deletion.
Connection scope: Bluetooth. Symptom: Switching between devices isn’t working.
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.
