When this guide applies

Exact WH-CH730N, not WH-CH720N. The new source is within one metre. No initialization is included; a ninth pairing replaces the record with the oldest connection date among eight stored records. Charging-accessory forum context is not a pairing-defect claim.

Connection scope: Bluetooth. Symptom: My devices won’t pair or reconnect.

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.

What owners have reported

These are public, self-reported experiences. They help explain the order of checks and the limits of a guide. They are not controlled tests, proof of a cause, a success rate or a substitute for the manufacturer instructions above.

User-reported WH-CH730N owner discussion about initial setup accessories

A participant who bought the model described lacking a USB-C charging cable and returning it; the wider thread also discusses use and model differences.

How this informs the checks: Check charging readiness before pairing and link the exact charging instructions; do not invent a model-wide Bluetooth bug from accessory confusion.

Limits: This is initial-setup context, not a report proving a pairing defect or a universal package-content claim. No outcome from the pairing procedure is reported.

Checks and possible outcomes

Start at charged. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

charged

Is the headset sufficiently charged for pairing?

Check the model’s documented charging indication rather than assuming no Bluetooth response means a radio fault.

Look for: Choose only the observation you can confirm.

Can you accept replacement of an old pairing if the list is full?

The CH730N stores eight source records. A ninth replaces the record with the oldest connection date. Continue only if that possible consequence is acceptable and you can pair the older source again if needed.
