Covers the Ultimate Ears Wonderboom firmware update details. Or lack thereof. Indeed we know of no way to upgrade the software on this speaker. Also, we find that currently, there are no firmware downloads listed for it on the Ultimate Ears web site. Additionally, neither do they supply any details for how to do this in the included manuals.
So perhaps the engineers feel that the speaker works well enough with the original firmware. Thus, they chose not to offer a (likely) confusing and difficult Ultimate Ears Wonderboom firmware update routine for such a rugged speaker that is already quite reliable.
Also, in our tests, the unit has proven to indeed be quite solid. E.g. We’ve found no bugs. Nor have we experienced any lost connections, distortion, crashes, or anything else bad. So firmware updating is likely not needed, and as far as we can tell, impossible for the average consumer to do.
