It was already some time ago but... From what I see here on this figure, Sinad should be still around 100dB (why this dotted horizontal line is so high?). Even considering slope of the result and harmonic distortion peaks, it looks much better than 80dB sinad... From what I ve seen (and heard) about A2049 and A2155 - both of them are around 97-100dB Sinad with great dynamic range. Without any audible distortion, even A2155 with its just 0.5Vrms output, can be amplified with +6dB (to 1V) or +12dB (to 2V) gain with any chosen good amplifier (I have ZenCan), and serve as a great DAC.But SINAD hardly reaches 79dB !
That's 20dB worse than the one Amir tested !
And, after some days, it just stops working.

No. The FFT matches the SINAD. Don't get confused by the vertical scale, look at the amplitude of the fundamental.It was already some time ago but...

Yup, amazing dongles considering size&price&sound.That being said, both my A2049 and A2155 perform identically, except for the 6dB lower peak output of course. Both have around 100dB SINAD.
I think any 3.5 mm usb-c dongle will do. I bought this in the local electronic store. Excellent

It will be good to have exact model number for adapters which have been tested.
Correct me if I'm wrong. For Google pixel 2 its GA00477WW model number. What about Apple?
Is that the latest one from Apple?The US model A2049.
It’s the current one sold by Apple for the US. The EU version does not measure as well.Is that the latest one from Apple?
Was I correct about Google's model number adapter and also the latest and the best one.
Thank you in advance.

There are phones that have a DAC and headphone amp inside, and that rely on dongles to output the analog audio via their USB Type-C port.This is an old thread that still goes on. I admit I haven't read all 47 pages. But what is this review about? Is the dongles job not only to conduct the analog electrical signal from the USB-C pins to a jack?
the us has half the output voltage, they perform the same when volume is same. SNR is better at higher volume, you wont be able to use that without connecting to an amp, and you wont hear it anywayIt’s the current one sold by Apple for the US. The EU version does not measure as well.

Oh! -Now I'm curious about that lightning to 3.5mm. jack I have that I use all the time for sound testing HiFi equipment. I wonder if that's an adapter or a DAC.There are phones that have a DAC and headphone amp inside, and that rely on dongles to output the analog audio via their USB Type-C port.
That is not what these dongles are.
The ones tested here have their own DAC, Headphone Amp, and ADC built into the Type-C plug. They're genuine USB DACs.
The performance of which is what Amir tested in this review.
Pretty sure it's the same as the USB-C one with a different connector. Apple will be forced (at least in Europe) to use USB-C on future iPhones so these lightning variations will disappear and apple will probably ultimately only sell the USB-C version - though I imagine the Europe one will continue to be limited compared to the US versionOh! -Now I'm curious about that lightning to 3.5mm. jack I have that I use all the time for sound testing HiFi equipment.
