Unfortunately the problem also occurs with Android smartphones.

This evening I made my first outing with the Q3, listening to the music at low volume and when I arrived at the house it began to emit a very strong interference that forced me to remove the headphones and turn it off.

I would like to know from FIIO if they are aware of this problem and if it has been solved in any way

At the very least, FiiO could stop saying they "shielded" the internal components.
At one point, I tried wrapping the exterior of the Q3 in a shielding tape, and it marginally improved it.

As far as I'm concerned, mine will return to the sender, too bad because I like the way it sounds

I have the same problem and at this moment I think it’s pretty useless to use with my iPhone 11 Pro.

We are very sorry for the trouble we have caused you.
It does work better with an Apple phone.

I am having significant EMI/static issues with my iPhone X. The interference is frustrating as the Q3 is a truly excellent product otherwise. Interestingly, the static seems worse then when I first received the unit. The Q3 cannot be satisfactorily used stacked on/with the phone. That was my intended purpose. I will need to look elsewhere for a pocket-friendly amp solution.

Sorry,
1, Q3, like many hifi headphones, uses a large number of precision & high-speed op-amps to ensure audio performance, and these devices are also sensitive to external interference.
2, we have designed it with multiple protections against external interference, which can be seen in the product diagram of the anti-interference measures in the product introduction. These measures can reduce the interference to very low, and in our laboratory test environment can not hear the explicit noise
3, the actual user use environment is very different, interference sound with the user's mobile phone antenna position, coverage angle, and even the user's environment cellular signal strength have a great relationship. If the bundle is still unacceptable, please try to switch the mobile phone network or not to bundle with the mobile phone closely.
4,2G/3G/4G/5G signal interference is not the same, especially under 2G interference can not be solved, because the 2G system determines the peak power of the wireless signal is very strong.

It is phone and carrier dependant.
I haven't experienced any issues with my Xiaomi Note 9 pro with 4G signals.

I wonder if aluminum backed phones will see better performance. I believe both the iPhone 11 and X are glass backed. My iPhone 11 was terrible with the Q3, will have to try it with the iPhone 12.

I wonder why I don't get the same problem with my BTR5 in USB DAC mode, it works perfectly and even placing it on my smartphone, it doesn't emit any interference, yet no protection has been vaunted in the specs

I suppose because inside the Q3 there are parts more sensitive to EMI.

It's worth checking if it's not caused by the poor and thin stock usb cable. I bought the FiiO LT-TC1 which is shielded and significantly better quality cable, so far all works well
@FiiO Willson why you equipped the Q3 with such a crap cables?

As I have already written, I also own the LT-TC1 cable and the problem remains the same.

The Q3 interference, which has little to do with the Cable, may vary from individual machine to machine.

In fact this interference is relatively minor, but we do a lot of work to reduce it, and this is probably the best we can do at the moment.

Jak lépe připoutat Q3 k mobilnímu telefonu?

Q3 může být rušen, pokud je příliš blízko k oblasti antény telefonu. Pro lepší připoutání Q3 k mobilnímu telefonu můžete vyzkoušet následující metody:

I solved the problem with the antenna by using the food foil that I put in the bag and between the iphone and q3. The interference completely disappeared. I'm sorry for my bad English I'm from the Czech Republic…

Hi, can I use this cable for my FiiO Q3? My Lt-LT1 broke in a few days.
