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.
Checks and possible outcomes

Identify the original passive cable
With playback paused inspect the supplied audio lead and its existing wired connection to a compatible headphone output. Do not substitute a balanced adapter or a USB cable.
Look for: Observe the named indication or available control; stop if absent.
- If I completed this check → Read the documented microphone boundary
- If I cannot complete this → Continue with source and model support

Read the documented microphone boundary
The manual explicitly says the included cable has no microphone and the product will not pick up your voice through that wired connection. Headphone playback working does not add a mic conductor.
Look for: Observe the named indication or available control; stop if absent.
- If I completed this check → Keep the call input distinction clear
- If I cannot complete this → Continue with source and model support
- If I cannot determine this → More information is required

Keep the call input distinction clear
Inspect the intended call application’s displayed microphone identity without changing it. A laptop or phone microphone is a separate source, not proof the headphone microphone works over the passive cable.
Look for: Observe the named indication or available control; stop if absent.
