Nexus 7 Car install questions - Nexus 7 General

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.

Qualcomm DAC isn't impressive

I was using some hi-fi earphones on this phone and was getting enough power from the phone. I have DSPManager equalizer installed and I nearly had to have the volume bar full just to get decent volume. Kind of sucks, but I can't complain too much for how good the price was. Will any developers be working on this chipset?
i think chinese phone could be great and could be compare with this incredible phone

Which hi-fi earphones you are using?
With your case, I suggest you buy a headphone amp like Fiio E5 to deal with your high impedence headphones.

How good are the Fiio E5's? I have been looking for something to give my 8323's a little something extra and does it work with an inline mic?

It's just a headphone amp. I haven't tried with an mic so I don't know. Don't expect too much from its price point.
But for 99% people E5 will work great. I'm using E5 with my laptop and Grado headphone.

Not expecting too much, just a little extra "oomph" in power to where I don't have to have the volume up to 100% and it still sound low.

E5 can definitely do that.
I just tried connecting my Grado to N4 without the amp. And the volume is perfect for me.
Also tried connect the phone to E5 and does amplify a bit, not a lot though.
There's also an E6 for a few bucks more. The power output spec:
E5:
Output Power: 100mW (32ohms Load) 18mW (300ohms Load)
E6:
Output Power: 150mW (16Ohm), 16mW (300Ohm)
Fiio has a whole line of portable headphone amps. Check them out on Amazon.com
Thanks, I kinda like the look of the E6 more, it's less "iPod shuffle"
The E6 is a good little amp but it will only drive headphones/earphones volume-wise. If you want something that will actually make them sound better, you'll have to step it up to an E7 or an E11. I have an E17 and it's great. The bonus with the E7 and E17 is that you can plug it into your computer via USB and use it as a DAC as well as an amp without installing any drivers.
An amp will not make the source sound better. It takes the existing signal and amplifies it. If it is a poorly designed amplifier, it may even add distortion and make the signal worse. You may hear an improvement if the amplifier on the SOC can not adequately power your headphones (likely due to either high impedance or low sensitivity, or both) and you drive it into distortion. So, if this is the case then you may hear an improvement. Given some of the lack luster results from the GSMArena testing, it may be more than just the amplifier though.
Some phones with USB OTG can use mobile USB DACs, which would likely improve SQ considering the state of sound quality on mobile SOCs. They also tend to have decent quality amplifiers as well. I'm not sure we can do this with the Nexus 4 yet, but it is possible on the GS3 and I'd suspect it's only a matter of time before we get it here as well.
If you are having volume issues its almost certainly because your headphones are low impedance. Lower than the inbuilt amplifier can supply. You can easily verify by plugging in another set of crappy earphones.
As was suggested, amp is your solution or you can use one of the phones that have a more powerful amplifier. I guess some of the HTC ones may have that though I have never used them.

Most USB DACs under $100 are cheaply made anyway. So there's no point to further drain your phone battery with a very minimal improvement over sound quality.
If you are really into it, use local FLAC and a small headphone amp. The best balance between mobility and audio.

The DAC in the nexus 4 drives high end IEMs easily, using hi end hifi equipment on phones and expecting it to work as Intended is bad logic
Sent from my Nexus 4 using Tapatalk 2
I found the DAC in the US SGS3 to be quite adequate for a mobile chipset, and seeing as the Nexus 4 uses the same one, I see no reason to think any differently. However, I do think the SGS3 has a more powerful amp in it. If your headphones are anywhere from 50 to 300ohm impedance, you will need an amp to get adequate volume (and sound quality) out of them. Obviously a good amp cannot make up for a poor source, but if your headphones are suffering from low power, an amp will help.
My Beyerdynamic Custom One Pros are 16ohm and I still have to turn my Nexus 4 up to ~75% volume to get them at a good listening volume. They sound great though. Obviously they sound better out of my Schiit Lyr, but my HD650s benefit more from the amount of power that bad boy puts out. I actually have to run my COPs through my E17 because the Lyr is so powerful (with a high output impedance) that it causes a low hissing on the COPs no matter the volume.

I am never a fan of RighMark Audio Analyzer from when it's written...long time ago.
But people like to compare numbers and RMAA shows some pseudo relationship between numbers and apparent audio quality.
I miss the days when you actually need to LISTEN TO THE ACTUAL DEVICE instead of staring at some numbers.

I don't really want to get into a discussion on what kind of differences can be heard with what kind of headphones when connected to a phone.
High-end is a very general term and doesn't really mean anything to me. If the built-in amp cannot supply enough current to the low impedance headphones, voltage (and volume) will drop. Since the OP was complaining about volume, using an external amplifier is his solution, or otherwise getting a phone that has a better built in amp. He can easily verify if the volume drop is caused by impedance by plugging in a high impedance headset and seeing if the volume reaches his desired level.

The frequency response chart pretty much exactly described my first impression when I listened to mine.
Another thing curious is that the stats are quite different from those of the other Qualcom SoC phones (some better, some worse -- including compared to new LG with identical hardware.) I would have thought it to be near identical; most of the previous ones are in a very tight range. Perhaps the difference is due to different parties testing (Supercurio/Anandtech vs. GSMarena)?

im not sure how they test but the N4 gives some odd results, it changes alot based on the volume you set it to i believe they mention it in the anandtech review from memory, but it seems to click into different 'modes' at different volumes its kinda weird and probably software related.
wait and see what kernel devs cook up maybe.

Usb type c audio jack sound better?

Hi guys I was not too happy with the built in dac on the note 8 and a friend recommended buying a usb c to headphone adapter as apparently have there own dac built in so I bought the htc one http://www.htc.com/uk/accessories/usb-c-digital-to-3-5mm/
And I don't know if I'm hearing things but it does sound louder with the adapter or am I just hearing it different?
My question is if it's true about these adapters having there own dac is there a better one the the htc obviously in a reasonable price range ive seen the one with the razor phone is ment to be good
And if this is the case I don't see the big fuss about looking the headphone jack if we can get great sound from the adapters lol
Thanks

Are you sure your friend didn't say that usb would use the headunit dac instead? I know that works that way, usb c to usb into my headunit for direct file play using only the headunit dac not headunit dac+ phone dac. No, I can't see any adapters your talking about having built into dac.
I can also tell you that I can't use high res in poweramp through usb or UHQ upscaler in settings with usb audio. I prob won't use it much due to those reasons, or Bluetooth for poor audio quality and no uhq upscaler either. Leaving aux for being the best for audio on this phone.

The moment you use the usb-c port to play your music, it bypasses the internal DAC. This is why ALL usb-c earbuds etc have their own DAC. I honestly doubt an adapter-DAC combo less than 10 pounds will outperform the DAC in the Note 8.
There is a major distinction between
1. How the DAC processes and shapes your music.
2. How 'powerful' it is and if it can handle high impedance headphones.
Seems to me that no. 2 is likely but definitely not no.1 with the adapter you linked.
It is well known that LOUDNESS(not volume) often comes across as BETTER quality sound.
Thanks guys I'm no audiophile I just wanted better and louder sound which the usb c headphone adapter seems (placebo maybe) do I've looked around on Amazon with a few of them claiming that they have decent dac built it
Do these dac in the adapters bypass the phone dac or something ?

Purchase recommendations for 3.5mm jack adapter on usb type c improves the sound qual

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.

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

Type C to 3.5mm possible?

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 am waiting to hear that too, I ordered mine. I had a V20 before and it was brilliant.
Probably Cirrus Logic CS47L93 as with Exynos S9. GSMArena's measurements are very promising but I take them with a grain of salt. I'm still wondering about output voltage though, as PhoneArena hasn't done the measurement for the Note 9, although it was measured at 0.75V for the S9. That should be decent enough for most consumer-level headphones but still lower than past iPhones or HTCs that had headphone jacks, or LG V-series.

I am not sure about wired big headphones, but the volume from the headphone jack is pretty good on the bundles AKG's. The HTC 10 etc are something else, but I wasn't impressed with the ourput from iphones or the V series DAC's. Not enough volume.
htc10>Note9
so going from my htc10 to note 9 is a step down?
kindly do let us know.
thanks.
In my opinion, I don't think it's a step down in real audio quality to the ear on the snapdragon. The HTC doesn't perform as good as an external DAC, IMO and I don't notice a big difference on the devices. I had the same questions, being a lifelong HTC guy. But if you've got more sensitive ears than me or different audio profiles you may hear a difference.
I use the ear-studio ES-100 portable DAC and Bluetooth DAC and if you go that route, I highly recommend it.

I think audio detail/clarity is pretty similar to the HTC10. The output is much weaker though. I have low impedance earphones so it's not much of a struggle. Higher impedance headphones may not achieve the same volume levels. I know GSM Arena rated the audio very highly if I remember. Not as good as the LG, but close.
well, that is my main concern, maybe it is my imagination but having the headphones pumping out music at half the maximum of the htc10 made me feel good...(i Know i'm weird)
i migrated from s6e+ to the htc10, day and night difference in audio quality between the two.
if the note9 can do better (at least better than the 10) i'd bag it. Oh Well maybe next year sammy
Like the S9, the DAC on the exynos version is probably a custom Cirrus Logic CS47L93 design and very highly regarded in the audiophile world (unlike the AqSTIC DAC in the snapdragon version).
Its almost identical pretty much to the fantastic CS43131: https://www.cirrus.com/products/cs43131/
However the DAC is only half the story. True amplification and impedance plays a big part when driving high powered earphones. But it is the audio tuning that is key. The reason why high end audio separates like Nad, Arcam and Cambridge Audio etc beat the still great quality of a SONOS is down to stellar audio engineering, crossover interference minimisation and high quality internals etc.
Samsung have actually done a decent job here. There is a difference in quality between their snapdragon and exynos (though they also tuned the Aqstic to the best if its capabilities to be fair, but the soundstage on the exynos is more apparent).
HTC 10 used Aqstic as well, but they use a Class D amp alongside it. Previously they only depended on using the integrated DACs for their SoC, usually with a Class D amp at ~1V. The Mediatek devices had a Wolfson DAC and the results were pretty comparable between them. That said, some reviewers did note that HTC's headphone output has clipping distortion at maximum volume (although it is said to be blaringly loud). I had the HTC Butterfly s before that and despite GSMArena giving it an outstanding audio, and it had this issue along with hissing. Its volume isn't particularly high either, and according to PhoneArena its output was only 0.35V, which is odd for an HTC. Also, its headphone jack wasn't very durable and got damaged when the cable got strained.
I'm still curious to see measurements from the Snapdragon Note 9 and the output voltage of the Note 9. S9/S9+ is 0.75V. I think the volume is excellent for IEMs, but for over-ear headphones it is still little low. Audio-Technica MSR7 is quite loud, but the Takstar Pro 82 and 1More MK802 still require a fair bit of volume to match it - all are 32 ohms. I also used the Sony Xperia Z5 which also had only 0.35V headphone output, but it was louder than the HTC at max volume without any bass clipping distortion. MSR7 was quite loud at maximum volume but the other two were borderline in terms of volume. The overall sound was brighter with a slight roll-off in the bass. Quite a few users complained about the DAC but I thought it wasn't too bad. I think the Note 9's is less brittle-sounding and more subtle with the treble, but still detailed. The headphone jack was also more durable than the HTC's although I've had an occasion where it temporarily failed on me and I needed to use SoundAbout to force detection (there were many complaints of such happening to Xperia phones). I'm wondering if Samsung Galaxy headphone jacks are more durable?

some good points of note here- see what i did there lol! . Also we must not forget how a more powerful headphone amp may have a hit on the battery as its essentially providing more power to the more hungry headphones available in the wilderness. The Note 9 is marketed more or less with the business user in mind. Battery priority (and we can debate til the cows come home about battery!) seems to be favouring other areas and its wired audiophile capabilities are not a main selling point...

Then you should know about how to "trick" the LG phones with Quad DACs built-in into switching to their louder modes. The modes are: Normal device (lowest volume), Aux/External Device Detected (next louder), and High Impedance Mode (aka "HIM", the loudest).
How do you do this? There's a couple ways. If you want it just a LITTLE louder (Aux mode), connect the male side of a male 3.5mm to female 3.5mm adapter into the LG phone, and then connect the headphone jack into the female side of the adapter. Boom! Instant Aux mode!
Not loud enough?? lol Then buy a high impedance adapter off eBay like this one (MUST be the 75 ohm, or higher, but 75 ohm is better). This will put the phone into HIM and drive headphones up to 600 ohms. Just do the same process mentioned above for Aux.

Not loud enough?? lol Then buy a high impedance adapter off eBay like this one (MUST be the 75 ohm, or higher, but 75 ohm is better). This will put the phone into HIM and drive headphones up to 600 ohms. Just do the same process mentioned above for Aux.

Adds more hardware into the signal path thus creating potential for static and getting a less clean background. I'd rather have less volume with clean signal than distortion or clipping.

Potential, maybe. But I was doing the Aux method for several months on my LG V30, and I never heard ANY kind of static or distortion at all. The pros by far outweigh the cons here. Having that extra amp power strongly benefits the sound coming through your headphones.

Having a low noise floor and ample headroom far outweigh potentials like static or loss of hearing because I want cannons, not speakers on my ears. Plus, I have a portable amp, JDS Labs CD5 which can make my Beyerdynamics COP or 770pro 250 ohms rattle my chest if I want to lose my hearing. ?

That's always another option too, but the convenience that comes with only having one device should be considered too. And the V30's Quad DAC is pretty amazing. It was able to match up with my old $300 Oppo HA-2 amp/DAC device as well.
I got the DT 1770 Pro a few months ago and LOVE it too! Beyerdynamic makes some fantastic headphones!!

My V20 is my DAP now. Plenty of volume with built in amp. The CD5 is pretty compact. Able to rubber band it with a phone easily but I've hardly used it since the V20. Yeah. I need to get some Beyerdynamics 600ohm or open headphones. I like both of mine but want something a little more airy or different.

Yeah the volume I get from HIM is just right for me too ftw.
Yes the Quad DAC has made things a bit easier. I don't know if my next phone will be LG but if it's not I will very likely just get this bad boy........the Radsone ES100, which several ppl on Head-Fi and Amazon customer reviewers have stated sounds better than their former wired setup (with amp/DAC). I think the secret is that it has a DUAL DAC setup, and LDAC ftw. We'll see. Or else the wired Sabaj Da3, which several ppl have claimed outdoes the AudioQuest DragonFly Red. Though with the latter (Da3) I would have to carry my charger with me if I go long distance or into the city which I frequently do. lol
I've never tried any of their 600 ohm ones. I went through MANY headphones over the last 4 years to get to where I'm at now. I'm in NO hurry to upgrade anytime soon, though if I did, it would most likely be the MrSpeakers AEON Flow closed, or else Esther-C. I travel by train into the city a lot as I'd mentioned, so open-back doesn't work for me. lol
Do any of those amps have the Asahi Kasei 4458 or 4490? I would love to hear the 4490s in a phone tuned proper. I have a microprocessor with the 4458 and it is damn good. And the 4490 is better.
I wonder is Samsung peeks over Motorola's shoulder. Battery mods would actually be pretty cool for note series. An extra few mm ergonomic battery mods would serve as a good base for sketching and drawing on a tablet especially. The note9 would rock the boat with Dex and a decent 1080p projector. Stackable mod with speakers. Or Asahi Kasei 4490/4458 DAC headphone amp.
With battery mods that can easily swap batteries to recycle, make them stackable and polish Dex even more along with other endeavors. Hear me Samsung? Good hardware and software long term ideas. It will be done.
Sorry I am reading the Paris Agreement. ???
