I have few of them because HTC U11 Life does not have headphones jack.
Both HTC and generic work as it's supposed to.
Even G6 has its own headphones jack, the D/A adapter has slightly better sound with Koss Porta Pro

Looks like the bundled male USB-C to female USB-A adapter's intended purpose is to help users transfer their data from old phone to new Pixel.
However, I have a Fiio Q1 Mark II DAC/AMP that has micro USB as input so I used the bundled USB-C to USB-A adapter to connect my Pixel 2 to this DAC but audio still comes out from the phone's speakers.
How can I output the audio through USB-C? In developer options, I select USB Configuration to "Audio Source" but nothing changed. Or I need to use a USB-C to micro USB cable?
To clarify things, here is my configurations: Pixel 2 <-> bundled USB-C to A adapter <-> normal micro USB cable <-> Fiio DAC <-> Headphones (3.5mm jack)
Thanks.
You should be able to use the combined line-in/line-out port instead of the micro-USB, though this would require you to first use the bundled USB-C to 3.5mm adapter. This is problematic if you're not rooted since the Google DAC has terrible distortion, and can only be fixed with root. The setup would be:
Pixel 2 -> Google USB-C to 3.5mm DAC (digital gain <75%) -> 3.5 male to 3.5 male -> Fiio Q1 DAC using 3.5mm line-in -> Headphones
A USB-C to micro-USB cable may work.

Thanks for your reply.
I have finally made it work. USB-C peripherals must be connected in order. You need to power on the DAC first, connect the micro USB input then connect the USB-C to the Pixel last so the Pixel would recognize the device on the other end.
Another question raised. I have also tried connecting Fiio DAC to iPhone via micro USB to Lightning cable. It worked instantly. iPhone wouldn't let me adjust volume on the phone. Everything was handled by Fiio. Which I think is the correct way to do it since iPhone is just sending digital signal to the DAC and let it do all the work.
But with the Pixel, I'm still able to adjust volume on the phone. I wonder why the phone could do it since it should not do anything with the digital audio signal. I also would like to know how loud should I set the volume at phone and adjust the rest at the AMP.
Also, Pixel's battery is draining fast! Because USB-C supports charging connected devices. I'm not able to disable USB-C power output. The LED light on Fiio indicates that it's charging. The reason that I didn't want to use Google's USB-C to 3.5mm DAC is because the distortion issue. I believe Fiio DAC is much more powerful and audio quality is better.

Apple I believe uses a line level, the Pixel's is amplified so you can still control it on the phone.
I'd recommend hopping over the the Pixel 2 XL forum, there are technical details that might answer your question. Objective sound measurements.
Regarding the Google DAC, the distortion goes away below about 75% digital gain. In that chained setup, you'd be looking to send as pure a signal as possible with little to no digital gain to the Fiio, which would then cleanly amplify it for playback.
Hi. The audio is okay on the phone. Good with earphones but okay when I use the headphone jack to my car stereo input. Why not bluetooth? Its because direct connect provides the best sound. NOW HEAR THIS. I plugged in my essential phones usb head jack adapter (essential phone has no headphone jack but they do provide a USB C headphone jack dongle) and its like a WOW. I couldn't believe how much the quality of the audio improved. I am talking about tremendous improvement. Like a different phone WOW. Now whether it was due to essential having a dac chip in the dongle (I think it does) I have no clue. I was shocked because normally the question would be why does a dac chip USB C headphone cable work on a phone with a headphone jack? Did Moto decide at the last design phase was to include a built in jack? The dac cables only supposed to work on phone like the essential or the google pixel 2 etc if I am correct.. Well i am da.... sure glad it works on the Moto G6. How you proceed with what you get/prefer to purchase is up to you. I don't know what the end result will be because I truly don't know. The one I have from essential worked miracle wonders. I only suspect it will work with other USB C dongles with a dac chip. Man, i am digging this phones audio improvement. I am like WOW.
Check it out with something like Viper installed and disable Dolby for a little while to see if that also improves the sound. I use an aux cord to play music in my car as well the Viper HiFi Magisk module on top of tweaking some of my head unit settings, and it puts out some of the best sound for music. Can get my old 2004 Carolla to sound like it has a 10-11" sub in it just from the stock stereos and a Pioneer head unit ;p
Not really that big of a surprise, considering that my old Moto E4 would use a pair of USB-A headphones plugged into a OTG adapter. Feel free to call me out, but isn't the USB-C headphone dongle just getting talked to by the phone like a USB sound card?
Most newer (and some older) phones are all capable of USB audio routing. Just take a look in developer options to see some settings.
Hey I was wondering if the Type-C to 3.5mm adapter can power high-impedance (i.e. HD600, R70x) headphones well enough to not buy a dedicated headphone DAC and amp. I was wondering if anyone with high-impedance headphones could test it out with their HTC U11.
Coming from LG G7 Thinq+, which as best headphone DAC ever build in a smartphone, S10e DAC sounds inferior. Even though Samsung says it supports 32bit audio, it's not satisfying enough.
Can anybody suggest any external portable Amp or Amp + DAC to get the audio sound closer to LG's DAC?
Is only an Amp is enough or do I need to buy a DAC + Amp to drive high impedance headphones?
Audio output from the 3.5mm Jack is lacking. Looking for a solution.
It looks like Edge 2021 supports USB-C analog out.
Moto Z3 headphones adapter works.
For what it's worth, these also work well with the Edge 2021. Just confirming for anyone who doesn't have a spare USB C dongle handy.
