Do you have a device analog or digital? You will not know until it breaks.

 
 
 
Smartphone manufacturers: it's time to listen to us when we say that we need to return the 3.5 mm headphone jack back to the phones, at least until you figure out how the USB-C works. After connecting a bunch of USB-C dongles and headphones to the USB-C phones, I found that in general there is a mess in this area, especially if you take third-party headphones. And that's why.
 
 

Why not connect any USB-C device to any phone

 
The first problem is the lack of basic compatibility. For example, if you take a USB-C dongle that was bundled with the Motorola Z2 Force or Sony Xperia XZ? then it will not work with Google Pixel 2 XL, Samsung Galaxy S8 or OnePlus 6.
 
 
In this case, the Pixel 2 XL dongle will work with all listed phones, like the headphones that come with the Huawei P20 Pro.
 
 
But if you take the dongle from the box with the Huawei P20 Pro and connect it to the Pixel 2 XL, the result will not work.
 
 
And, yes, the headphones from HTC U11 also do not work on many phones. In such cases sometimes you just want to crush the headphones or dongle.
 
Google plans sell digital USB-C dongles for $ 20. (If you need such a thing, you can buy it at a more reasonable price of $ 9 ) W2w2w20.)
 
 
 
Connect an analog or passive USB-C audio adapter or headphones to Google Pixel 2XL, and you will not hear anything
 
 

The lack of uniformity of USB-C

 
Disappointment in all this is the lack of uniformity and logic. Why does the analog USB-C dongle not work on Pixel 2XL or OnePlus ? if both phones (at least their versions for the US) are based on Qualcomm Snapdragon 835 and Snapdragon 845 , both of which should include Aqstic's DACs?
 
 
In defense of Google, I will say that a representative of the company told us that they just follow the rules. Although analog audio can be transmitted via USB-C, it is not included in the specifications for headphones. This might be convenient, but there is no requirement, so, excuse me!
 
 
What's even more annoying is that several phones are working with a digital dongle from Pixel 2 XL, but only if you turn on the USB storage system. Yeah, very intuitive. Even worse, you need to do this every time you insert headphones or dongles.
 
 
 
LG G7 with digital headphones from Huawei P20 Pro does not work until you turn on the data transfer via USB - every time after connecting
 
 
However, there is hope.
 
 
Included with the Huawei P20 Pro are both digital headphones and analog dongle. You can get confused trying to use an analog dongle somewhere else, but the P20 Pro just works. He even tells you what exactly is happening, no matter what type of device is inserted into it.
 
 
 
 
With the digital headphones that come with it, it just works. If you are brave and plug in a third-party adapter, for example, a digital Dongle from Pixel 2XL, you will receive a warning - but it will still work and automatically power it. There will be no problems with the analog dongle.
 
 
 
Useful information from Huawei P20
 
 
Trying to figure out which phones do what, and which dongles and headphones are shipped with, I deduced certain patterns.
 
 

Phones with 3.5 mm and USB-C

 
Most phones (for example, LG G? Samsung Galaxy S8) with USB-C and 3.5 mm analog audio connectors work with digital headphones and dongles. However, most of them force you to include file transfer via USB-C after connection. But this is better than a non-working phone when you are on an airplane and want to listen to music. Almost no phone supports analog dongles, but since they have an audio connector, they are not needed.
 
 

Phones only with USB-C

 
On phones that get rid of 3.5 mm connectors, analog dongles work almost always. For example, Huawei P20 Pro works as it should. Sony Xperia XZ2 also works great with analog dongles, like the Lenovo Z2 Force (both have an analogue dongle).
 
 

However

 
I ran into exceptions, and I'm sure there are more of them, including Google Pixel 2 XL and the new Razer Phone. In them there is no analog transmission at all. And if Google sends you to a site where you can buy a digital accessory, then Razer Phone does not even bother to say why you do not have audio.
 
 
 
The good old analog headphone jack just works
 
 
And the problem will only widen when people update their devices and the number of USB-C headphones and dongles will grow. After all, admit: you can sell the phone or give, but headphones or dongles, most likely, leave it to yourself.
 
 
If only we had a practically universal technology or a port that would work exactly as expected Hmm
