Just an update I have given my 2 x Zen Blues the firmware update and have to say that without a doubt that the sound is a lot better than before and would recommend that if you have the opportunity to do the update you will not regret it but unfortunately its only available to Android devices at the moment. Keep up the good work iFi

How do you do this?
Go to
Select zen blue from the drop down menu and enter the device serial number.
The serial number is on the box or the back of the device, its a ten digit number.
This firmware has been available since January so not a recent update, if you haven't already updated it's definitely worth doing.
It makes the connection more stable and gives the option to turn off the led lights with a long press on the pair button.

I think I'm being dim - having downloaded all of that, how do I get the app onto my phone? Do I just copy & paste the .apk and .bin files, and if so, to where?

Why don't the people who write these guides just do it from the basics?

EDIT: Looking further along the instructions there are other points where I don't know how to do what they are asking. Why not design a proper app? Frustrating.

Thanks. It all feels a bit half-baked.
They use to have a tutorial on the website how to install the gaia control app, I take it that's now contained in the pdf file.

I did, and it was a bit of a pain to start with but eventually I got it working.
It was a while ago so its not clear in my mind, I do remember that I couldn't find the apk file in my downloads because I expected it to be the first file in the list. It turned out it was well down the list of downloads.

I have just noticed on mine that after I have paired with the unit the light goes off completely and stays off while playing anything.

That's what the firmware does, lights up to tell you what codec is being used and what the resolution is and then the led lights go off.
When you disconnect the blue/red led flashes for a couple of minutes then the led switches off.

Perhaps somebody can explain how firmware updates can change the sound? I can’t fathom it myself, though I’ve read similar suggestions on other forums about other kit.

I don't know about changing the sound but better connectivity this one had an issue with the Ldac codec which it fixes which has a knock on effect on how well the codec works and sounds.

Changes in the DSP, at the very least. My Naim streamer pre had this with it's latest update
Thanks, so that’s DSP meaning digital signal processing, but not in sense of the equaliser function often labelled that way? I thought the processing was done by the hardware, which is why I’m puzzled. Or does the firmware change the frequency response!

Don't know where the change takes place, but it did in my case. Of course, some didn't hear it, some preferred the latest one, and some (myself included) rolled back to the previous version.

I did have a bit of help from their support team and all done - a word of caution though - it won't work easily with some phones. My Sony won't work in the way suggested, but the Motorola does.

There's another update about to be issued which they are going to email to me directly - if anyone wants it, just ask.
