Here’s a helpful post for someone looking to update the portable Bluetooth speaker firmware.

Device Firmware Update (DFU)

If you have an original D9 unit and need to apply the update manually, you must put the device into mode using a PC: w-king d9 firmware update

1. Factory reset the speaker: Press and hold Power + Volume + for 10 seconds. This clears any old cached settings.
2. Test Bluetooth pairing – Pair with a phone and play music for 30 minutes. Check for dropouts.
3. Test TWS – If you have two D9 units, pair them in stereo mode.
4. Check sound quality – Listen for distortion at 80% volume. If it sounds worse, you might have used the wrong firmware (revert immediately via support).
5. Verify version – Some update tools allow a “Read Version” button. Otherwise, the change log will tell you what’s new.

Q: How often does W-King release firmware updates?

A: Rarely – maybe once every 12–18 months. You don’t need to check constantly unless you’re experiencing specific issues. W-King D9 Here’s a helpful post for someone
