It works on this older Android (LeEco LeMax 2) I've converted into a DAP, but not my new one. The volume is a bit low, but the device is rooted, and I can fix it with an edit...
Just a quick FYI: The dongle actually works on USB 2.0 ports as well. I've an aging Dell Optiplex 990 (desktop) that I'm using with it, and its output is controllable via Windows 10 Pro, and sounds just fine...
It seems that you indeed do...
It will affect the final output, yes, but it could still be fine. All depends on gain of the amp and the needs of your headphone(s).Also, will this affect me in anyway if im using a headphone amp?
...just in case that this has not been answered: Yes it works with volumio and R4 after reboot and soundS great. Output volume seems to be same as R4’s jacket. The dongle is even recognized by Roon when the Roon endpoint plug-in is installed.I just read this thread and wonder if it can be used with raspberry pi / Netbook + volumio? I'm hyped on ordering this until I read that it has problem with android. I have old Samsung A7 with USB C. At least if it can run with volumio I will consider buying it.
It seems A2049 US version is the best price performance dac money can buy right now for windows PCs. Also ADC is much more loud compared to laptop's microphone input.
With M50, it's volume going way up to ear penetrating levels even at %50; with AKG K7XX, it is uncomfortably loud at %85.
Biggest disadvantage is its build to break level meterial quality, a little diy reinforcing took care of it.
Overall very happy with my choice.

I'd like to know to. I fear cost of shipping would make the ~£10 price more like double that.Any suggestions where I can buy the US version from (A2049 ) ? I'm in UK, and would prefer to buy from Europe due to easier shipping. And ensure that it is A2049 , as I understand the box can be misleading. I can't seem to find it online without resorting to shipping from US/HK
I thought that fix was for the US version when used on non-apple hardware.
In which case the hardware is capable but purposefully crippling itself under certain circumstances. I understand that the EU one is just not worth bothering with full-stop. It isn't capable of 1v under any circumstance - hardware not built to do it, or firmware is un-fixable.
I bought one from amazon US via proxy and still got the EU one, lol...Any suggestions where I can buy the US version from (A2049 ) ?

Maybe the Samsung one? It measures almost the same and price wise is not so different.I fear you're right. So back to square one. A cheap dongle/dac for android that has 'reasonable' sound and isn't too much of a drain on phone battery...
Are these measurements still accurate? I just got an Apple dongle and tried it with the Focal Utopia, which I was excited about as I thought they would be the one set of high-end headphones I could use with a phone. I did the following calculations:
Focal Utopia impedance: 80 ohms
Apple adapter power at 33 ohms: 31 mW
31 mW * (33 ohm / 80 ohm) = 12 mW
Focal Utopia sensitivity: 104 dB / mW
Max volume = 104 dB + (3 dB * log2(12)) = around 112 dB
That should be quite loud. But even when I turn the volume all the way up, the headphones are just barely listenable. I'm getting maybe 80 dB.
Anyone know what's up here? I know it seems silly to connect $4,000 headphones to a $9 DAC, and I of course have a desktop rig, but I was actually looking forward to this working. The calculations say it should but it's not.
Is the Apple adapter louder on iPhone? I'm using it with an Android phone.
What model number is your Apple dongle (starting with an A and written on the cable wire of the dongle, don't trust the packaging). And what music player are you using on Android?
