Covers the JBL Clip 4 firmware update routine. But we know of no way to accomplish this. Plus, we currently find no firmware downloads for this speaker on the JBL web site. Neither do they give any details for this in the included manuals. And many folks have looked for, and commented on, this lack of firmware updates for the 4. Finally, the Clip 4 does not appear in the JBL Portable app. So applying updates via this apps is likely impossible.
JBL Clip 4 Firmware Update
The Speaker Works Well Without One
Thus it appears that JBL feels that the Clip 4 works well enough with the original firmware. So they do not author a (perhaps) confusing and complicated update procedure for such a basic speaker.
Indeed in our tests, the speaker is quite reliable. That is, we’ve not found any bugs, lost connections, distortion, or anything else bad. The speaker never crashes, locks up, nor sounds funny. So firmware updating is likely not necessary.
Perhaps They Can Update at the Factory – But Why Bother ?
Plus, as far as we can tell, it is impossible for the average consumer to perform. But there might be a way to do it for JBL engineers. So they might be able to do it with appropriate software running on a computer, via the USB-C port.
But this speaker just may be too simple for JBL or customers to bother with firmware updates. Indeed compared to bigger speakers, there’s just not very much in the firmware that goes wrong in the Clip 4.
