Sony X 11 Firmware Update Instructions

But there are currently no firmware downloads listed for this speaker on the Sony web site. Nor do they provide any details for this in the included manuals.

So apparently, Sony feels that the speaker works well with the fresh-out-of-box firmware. Thus, they did not include a (perhaps) confusing and risky update routine for such a simple little speaker.

Moreover in our tests, the speaker is indeed quite reliable with the onboard firmware included. I.e. We’ve not seen any bugs, lost connections, distortion, or anything else bad. So firmware updating is likely unnecessary, and as far as we can tell, impossible for the average consumer to pull off.

Finally, a no-update option makes the X 11 even easier to use for the tech avoiding consumer. And it’s good to see a speaker that works well, right out of the box, and will likely never need updates to fix problems. So if that’s the sort of hassle-free operation you’re looking for in a Bluetooth speaker, then the X 11 is for you. It’s a virtually zero-service model, and the only maintenance it needs is to keep it clean and to exercise the battery periodically.
