Ok, so I'm about to bite the bullet and get rid of my stereo and replace it with a Nexus 7. I was thinking about just getting a 1/8" phono to rca audio jack, but I see that a lot of you that are doing the install are using a USB DAC. Can someone explain to me why that is, and what the benefit is over just hooking the rca up to an amp?
Better DAC...and better preamp. The built in digital to analog for the headphones was built to a price for $200 tablet. And the analog amp for the headphones is expecting a high impedance load. Doing it through the headphones basically adds an extra analog conversion to the path (impedance matching from headphone level to rca level). An external dac bypasses this and converts directly from digital to rca level.

The first part is true, the DAC on the tablet is possibly a lower end one then what you'll find on an external DAC but you should spend a little time and investigate. Looking at ifix-it they don't mention an D/A converter or headphone amp. Often now it is built in to a power switching chip.
As far as the second part, the headphone amp is built to drive a low impedance (16ohms). The amp will have a high impedance (typically 500 to 1k, sometimes 10k). This is actually ideal. It maximizes the voltage your amplifier will see. And is the way amplifiers typically work.
The final thing I can say is output voltage. An external D/A might or might not drive more voltage out.
My experience is 15 years car audio installation and two degrees in electronics. I'm currently doing the same and starting a product line of items that make installing tablets better then installing aftermarket decks.
This might help
So I've been working on this for a while. Might be helpful to you!
I'm currently with a hole in my dash, Flip-flopping on n7 or n10 install. I've tested this thing with the n10, n7 and the galaxy note2 so far.

You can use a USB DAC with a USB Hub. The Fifo one seems to be popular at about $50.
Honestly from 15 years of car audio experience I can say that the Headphone out of the N7 sounds pretty good. I really don't know that a DAC will make any difference. I think either way you will find your self having to use Awesome beats or some other EQ app to get the sound the way you want it, but I'm thinking I'll just use the headphone out my self.
I am looking for a 3.5 mm jack aif usb type c adapter, with which you can get the most out of music quality. I ask you to enlighten me and advice. A second question would be still, is the quality of the sound over a jack adapter worse than a built-in 3.5 mm jack connection. thank you for your help
There's no way you will hear a difference between 3.5mm jack and usb-c connector, because it's still the audio chip that "makes" the sound. Still, if you'd have headphones costing thousands of bucks, you'd never tell if 3.5mm or usb-c is better in phone. Mobile audio chips aren't so great all in all. That being said, adapter that comes with XZ2 is perfectly fine. Buy reasonably earphones and enjoy the music.
He's talking about external DAC... And it makes a huge difference if the DAC is decent. This way the sound is transmitted to the usbc hardware as a digital feed and is then decoded.

Check out this guy.
Qualcomm AQT1000 32bit/384kHz with playback dynamic range of 122dB.
I was actually interested in whether the sound on the included adapter is just as good as if you directly installed a jack. I would be interested in the technical data as far as the sound of the snapdragon 845 is concerned. at xz2
HTC U11 adapter is good enough. (I use and recommend it)
Sound quality is great, with no distortion and good (high) volume! (24bit/192kHz)
Sent from my Sony Xperia XZ2!
I also looked for that. but where can I buy the original?
In USA, HTC website.
From time to time it appears to sell.
https://www.htc.com/de/accessories/usb-c-digital-to-3-5mm/#!pid=htc-u11
that would be him? what is actually better with the adapter than with the sony?
The HTC adapter has a stronger AMP and better DAC inside.
but that's the adapter where I posted the link from
the SMSL DACs work, brought one over from my XZ1. But it has the same issue it did there, it'll only work through specific apps for local audio files and supported streams. I use USB Audio Player Pro, a paid app.
If you're just looking for an analogue pass through for USB C to 3.5mm and NOT a DAC, these from INGOUE work fine: https://www.amazon.com/Headphone-IN...533674928&sr=8-8&keywords=usb+c+3.5mm+adapter
Hello guys !
I am not sure if anyone has noticed (or I'd rather say, has felt annoyed) by the stock headphones or by the output produced by the regular Jack 3.5 through their Type-C to Jack converter, but I have...
Personally, I am very demanding when it comes to music, and by choosing a 850-euro phone, this possible "issue" didn't cross my mind before I bought it. It seems like listening to music on this phone, (using headphones of course) comes with pluses and minuses.
As a Pro feature, the sound is excellent, the lows and highs sound quite good actually, but (there is a big "BUT") the maximum volume is too quiet, compared to other mainstream phones on the market, using mainly Jack interface for the headphones. The maximum volume on this phone, when using headphones is about 70-75% of the maximum volume on other phones (Mi Note Pro, Samsung Galaxy series, IPhone).
I made sure "Dolby atmos" is enabled, I have even tried raising all the EQ parameters (so that the general volume may be increased), I have also tried preamp-ing the sound with apps like Poweramp or Speakerbooster, but they would only sound like forced, and not actually louder, and the result is the same.
So, my sole question is : what should I do/buy/try in order to get a LOUDER experience when using headphones ?
Thank you in advance !
P.S.: sorry if I'm being awkward, it's my first post on XDA. Cheers !
Is there a safety volume limiter on?

Because in wired mode the headphones are driven by the phone's amp and in Bluetooth they are driven by their own internal amp. Its why you can use wired mode even when the headphone battery is depleted.
How about any advice buying replacement earphones instead of the adapter? I'd rather just have one external thing to not lose. Are there any USB-C earphones that will do the same job as the replacement USB-C to 3.5mm for regular earphones?

I find it as loud as my S8 plus or Pixel 2 through headphones, but BT is where it's at for volume.

I don't think I need head/earphones. I have 2 pairs of earphones (Samsung and Sennheiser), a pair of HyperX Cloud Stinger II, and studio headsets from Focusrite. I have tried all of them. And they are not the problem.
I've had many Huawei phones and 3,5mm volume has always been too low

I use the HTC dongle linked in the video above. It makes a noticeable difference. Even my cheap £15 earphones are much louder using it over the Huawei dongle.
It won't blow you away, so be realistic but it is DEFINITELY a noticeable improvement and worth the investment if you listen to music.
In fact, even my larger headphones were louder but I think you need a dac/amp to really enjoy louder volumes on large headphones. It's the cheap earphones that I found gave the loudest sound.
Is that possible to use the type c to 3.5mm converter for 7 plus?
why?! you have 3,5 mm jack
I have a HTC Usb to 3.5mm adaptor that I used on my HTC U ultra and it works great with the Nokia 7 plus as well.
I think the audio is louder using the adaptor and better quality.

Want to know does it worths to buy the adaptor just for sound quality improvement?
That's a difficult question as I always find audio a very personal thing.
I have just tried my Akg K451 headphones with both the audio jack on the phone and the HTC adaptor.
The HTC 3.5 mm adaptor is significantly louder than the audio jack at full volume. I notice some distortion in the audio jack that is absent on the HTC adaptor. I think the audio from the adaptor is fuller and far more pleasing to my ear.
I have no idea how these things work, for instance does the HTC adaptor have its own DAC or is it simply a pass through device? The difference in audio level would suggest to me the presence of its own DAC so maybe that would account for the difference in audio .
Maybe it's worth buying the adaptor just to drive certain headphones better. I have a pair of status audio headphones at home that I normally use with a headphone amp to drive them I will try them on the 7 plus later to see how they sound with the audio jack and the adaptor.
Sorry I can't be more definitive.
By the way the HTC adaptor is around £10 in the UK direct from HTC.
Is the sound quality and volume really that bad or is it just some specific/batch units?
I listen to a lot of audiobooks on the go and it would be a shame if this was a dealbreaker.
No I don't find the audio particularly bad and most of the time it is loud enough.
Most of the time I use the 3.5 jack and don't have a problem but when I'm sitting listening to music and doing nothing else I prefer the audio from my HTC adapter.
The volume will depend on the impeadence of the headphones used, my AKG headphones are always much louder than my status audio ones when used in the same device.

I think it can，I used a Xiaomi's type-c headset that can be used
Quite strangely, My Mi A2's USB-C to 3.5 adapter DOES NOT WORK with my Nokia 7+
Has anyone used some type of USB-C->3.5mm adapter to route audio out with any luck? I'm looking to use my current my wired headphones and my car stereo aux port. I know old lol. My wireless BeatsX suck, they dont get loud at all. The wired Beats I got 6 years ago blows these POS of earbuds out of the water. Looking for any suggestions on an adapter and any special config required in android. Currently running rooted stock. Thanks.
UPDATE - I found a great adapter that works with my car aux port with no problems. https://www.amazon.com/gp/product/B07BTVQ8YC/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
Great quality, good price... $9.99
Currently I am using adapter from Xiaomi MiA2, works perfectly with aux in my car and wired JBL headphones. This adapter looks and feels cheap but works really well. I think every adapter should work, just buy generic one

Thanks everyone for the reply!!
Just so you know more: every adapter should work indeed.
But these adapters contain DAC (digital to analogic converter), in order to receive sound through USB and sending it through good old analogic 3.5mm. The quality of these DAC can really have a difference in sound quality. Not on standard car environment, sure, but for someone with good earphones it is worthwhile to search for a little quality for these adapters.

The OEM adapter does not have a DAC. It doesn't need one because it's correctly wired to work with the USB audio out on the OnePlus devices. So if you use this one, you're actually using the DAC in the phone itself.
I've got the Apple one (the only apple product own!)
According to head-fi (an audiphoile forum) it's one of the best that doesn;t cost a fortune.

Actually it sucks (at least for the OnePlus 7T), I got one too and I regret, the sound volume is really bad with the apple adapter because it wasn't made for Android phones at all of course.
I went to a miniso store and got one adapter there and is 5x times better than the Apple one, and cost 3x less. xd
Any splitter for simultaneous 3.5mm & charging which supports fast charging?
I've seen some videos on YouTube, but doesn't seem like supporting fast charging. We've real USB3.1, there should be something out there.
I'll receive an Audio Technica headphone this week. Could someone please tell which adapter will work best for our 7t?

I tried one (from Ali Express). It is unusable while charging as I started hearing motor sound after one minute of usage. Unplug and plug that back in, again same issue in a minute. None of such adapters support fast charging as far as I know.
