thanks for answering
That is my doubt ... I do not use any of those applications. I use Google Play Music
 
If the Q1 is not going to work with Play Music that another option I have? 
I would like something in that price range and very portable and that when plugged with otg cable can improve the quality of the streaming
 
Regards

Dear Sito Lupion,
 
Thank you for the support to us. Maybe you can go to the local store to have a try by yourself first to see whether the Q1 or some other product can be compatible with your phone.
 
Best regards

Hi Guys,
 
Take a look at the attached picture.
 
My iPhone is no longer playing nice with my Fiio Q1.  
 
As you can see, I'm connecting the two devices like this:

1. iPhone 6s   ->   Lightning to USB Camera Adapter   ->   USB 2.0-Micro-USB to USB Cable   ->   Fiio Q1

 
​Up until a few days ago, this was working fine.  But now I keep getting the message, "This accessory is not supported by this iPhone".
 
Is there a solution to this problem?

• Make sure that you haven't inadvertantly switched the USB charge button at the bottom from off to on.  If its drawing too much charge from the iPhone you'll get that message.
   
• Could be the cable pins - something not aligned properly or damaged.  Try this one (it is what I use) - shorter too

For reference, mine still works using iPhone SE + A5 + L19 cable mentioned above

Ditto having the charge function on. This is the only time it happens to me.

I do not have the charge function switched on.
 
My set-up was working fine up until a few days ago (using the USB 2.0-Micro-USB to USB Cable that you see in the photo I attached).  I really don't want to have to shell-out for a new cable... it there anything else here possibly causing the issue?
 
@holden4th
Are you using the same cable as me, or are you using the one recommended by @Brooko

It could be the CCK. The cck in your photo looks the same as mine, however, there are two models of this cck adapter. The original is the MD821ZM (also seen as MD821ZM/A). The newer one is the MD821AM/A which is what I believe I have though I no longer have the packaging to verify that. I vaguely remember reading that the exact issue you are having was also a problem with the older model which is why I bought the newer one though I could be wrong here. Both models have the model number A1440 on the female USB end so I don't know how you could tell them apart.
 
I also had a play with my Q1 and indeed when I turned the charge switch on I got the accessory unavailable message. I had to unplug and replug the cck to get my iPhone 7 (my previous phone was a 6S) playing through the Fiio again. It might also be worth checking to see if you have the CHG switch fully turned off or if it might be faulty. Plugging it into a USB charging source and checking the colour of the charge light could give you an indication.
 
 I am using the micro USB to USB cable that came with the Q1. It's just the right length. Is yours still around?
 
This site makes interesting reading (and confirms my CCK adapter theory)

Hope this helps you move towards solving your problem.

I checked, and my CCK adapter is the new one (MD821AM/A).
 
​I checked the CHG switch while plugged into my laptop, and it is not faulty (the light is blue when CHG is "off" and the list is pink/purple when the CHG is "on").
 
While plugged into my laptop, I tried the micro USB to USB cable that came with the Q1, as well as the micro USB to USB cable that I bought afterwards, and both work fine with the Q1 plugged into the laptop.  However, either of them work with the Q1 plugged into my iPone 6s
 
To recap:

1. The Q1 works fine with my laptop.
2. The Q1 no longer works with any of my iOS devices (iPhone 6s, iPad 4).
3. Both of my micro USB to USB cable work fine with Q1 + laptop.
4. Neither of my micro USB to UBS cables work with Q1 + my iOS devices (iPhone 6s, iPad 4).

 
Maybe my CCK adapter has been damaged?  It's the newer version (based on the serial numbers you gave).  It did work at one time; it doesn't work now though...

My only other thought is the lightning connector pins. I find that the ones I use to charge my iDevices can develop little black spots on the gold filaments and not work properly. This has happened more than once. You might need a new CCK adaptor.

Question, which is more prone to have connection problem, lightning/ 30 pin connector? I bought a cheap CCK (isn't original) and the iPhone detects it but never does work on USB/ SD card.
Now, I'm sure the problem is on the CCK, so am sourcing for an original MC531ZM/A, found a used and a new one... Wondering whether it's worth to choose the slightly cheaper used one and risk the same thing
Also, it does work with the Q1 right? My iPhone is 4S on iOS 9.3

When I had my 4S I never had any issues with any of the 30 pin connectors. It's only the lightning connectors that have given me an issue and this has happened more than once. These connectors have 8 gold lines which obviously provide the elcetrical connection. On lightning connectors that have failed some of those have been covered with something black. I suppose that I could have used isopropyl alcohol to clean them but haven't bothered as every Apple product I but supplies me with new connectors.

So, the other day, I go to put on my Ultrasone Pro 900s which were plugged into my Q1, which in turn was connected to a computer via USB cable. When I picked up the Ultrasones, I felt a small ESD shock when I grabbed the earphones. I didn't think much of it, as I've experienced static shocks with the Ultrasones before (mostly at my standing desk at work on carpet before I got a anti-fatigue mat). I theorize that it has something to do with the titanium drivers. At any rate, I fired up a FLAC file with VLC, and was blasted with a high pitched buzz in the right ear of the headphones. I thought I fried my headphones, but I tried another pair... same deal. In fact, every headphone, from every source (USB or 3.5mm cable) I tried produces this loud buzzing in the right ear. When I bypass the Q1, all headphones work perfectly. So something went horribly awry with the Q1. I contacted Fiio support and they are going to replace it, thank goodness. I was just wondering if anyone else has experienced this? Could the static electricity have traveled through the headphone cable to the Q1 and shorted some circuit or popped a cap? It seems unlikely, but that's the only thing I can think of. Or it was just a very strange coincidence. I've used the Q1 nearly every day for about a year at work, and never had any problems before. 
 
Thanks.

Since PCM5102 features two filter modes, linear and apodizing, I was wondering which filter does Q1 use by default?

Dear DjBobby,

Hi all,
I own a Fiio Q1 for around 4 weeks and I am very happy.
It works fine with all my computers and with my Samsung Galaxy S7 Edge. It is great with USB Player Pro and even works with Spotify (only have free account right now so no high quality streaming).
On the go I have a Momentum 2 In Ear Headphones, no problem to drive those.
At home I have a second hand HD600. I will try to test them with a more powerfull amp someday (chord mojo?) but for now I am really happy for what I am getting with his combo. I prefer the Q1 over my Yamaha RX-V473 AV receiver and usually listen to classical or acoustic music.
I can escape anywhere with my small Mobile + Q1 combo and enjoy my HD600 while the children are taking over the living room.

Dear FiiO
Thanks for the answer. Is it FIR interpolation or IIR interpolation filter? Since they are both offered in PCM5102. 
 
"The PCM5102 provides 2 types of interpolation filter. Users can select which filter to use by using the FLT pin (pin11)"

FLT Pin	Description
0	FIR Normal x8/x4/x2/x1 Interpolation Filters
1	IIR Low Latency x8/x4/x2/x1 Interpolation Filters
