Line Driver - Android Head-Units

Would it make sense to buy one of these for these Android head units? http://www.sonicelectronix.com/item_27392_PAC-LD-10.html
My amp is fine accepting 2v from the pre-outs, but I'm worried about the noise floor of these.

Grab this if you can. Not much more. Great for my Joying http://www.ebay.com/itm/American-Bass-ABX31A-3-Way-Active-Crossover-/400749157644

As an audiophile I can't help but giggle a bit, I don't think anything you can buy will really make the vogue sound all that great as the amount of noise to signal produced out of it is way too much - if you are thinking about buying bose headphones I HIGHLY recommend against as well, for $170 a pair of grado labs headphones or high-end sennheiser headphones will sound much much much better and you won't be giving your money to "blowse"
Honestly, your best bet is finding the original splitter that came with the phone and getting the absolute lowest impendence headphones you can - it will produce the absolute best sound you can get out of the phone (it's conditional though, so if you take those very same headphones and put them to another application like a home reciever it'll sound bad there!)
If any of this is confusing, let me know by PM I will gladly help out!
reply!!!!
Thanks for your reply.....
The splitter recevied from supplier doesnot match with bose jack.....so i have to have new splitter for matching bose jack(3.5mm) to enjoy sound....
Company supplied splitter has (1) charger jack & (2) 11 Pin mini USB for original HTC headsets.
So i wish considering above limitations, to enjoy good sound quality, i understood that BOSE is best matched with NOKIA N91......So i have planned to get one for me too provided i am able to fetch original HTC SPLITTER matching with subject BOSE headphones thread.........
Link provided in thread is of orignal HTC Splitter which I think released to use with HTC DIAMOND, Please confirm me that will it work on VOGUE also...if I buy one for me ???????????
lol, i've made my own and it works pretty darn fine. a wire is a wire. i really don't think its going to make a difference. (is pure gold wires really going to make a difference from copper?) but the quality of the magnet and the coils will make a difference no doubt.
but since my creation look ghetto (electric tape ) im planning on buying another.

Thread moved to General.
Difference between gold wires and copper wires do make some difference if you are looking at a very fine noise band.... but for the Vogue... completely agree with you
Only some people can actually hear the difference, but thats are the audio freaks. And the sound quality also depends on the device itself if it has a good amplifier integrated. (this is where ipods usually get criticized and where the zune is praised) Getting a amp will definatly increase the sound quality. what it does is basically what it is called, it amplifies notes to make them clearer and crisper

[Q] Use the Fascinate in Place of a car stereo?

Hey guys and girls. Recently someone decided to steal my stereo out of my 96 GMC Sonoma So I have a big hole in my dash and I should be getting my pre-ordered Fascinate tomorrow, as soon as Best Buy gets them in
The question I had was whether or not anyone here has the knowledge or could point me in the right direction to allow me to use my phone in place of my stereo. I was thinking of getting a dash mount and installing it in the dash where the stereo once was and routing the charger underneath as well. What I don't know is anything about the 3.5mm out. I know you can plug a 3.5 mm to RCA to get video out. I read a story today of how QuickPay has come out with a credit card reader that uses the 3.5mm port. I haven't found a good site that gives the specs on the output of the 3.5mm port audio tho.
I have the wiring diagram for my trucks electrical system, tho it doesn't show the impedance of the speakers. I know with my guitar amps and cabinets those specs matters and don't want to fry my phone by connecting it to the speakers with a rigged 3.5mm out to home made harness. I'm assuming there is hardware in the stereo that amplifies the signal to allow it to play on the 6 stocks speakers, but i'm not sure. I'm proficient with a soldering iron and have no problem heading to Radioshack for parts.
I dont know. If its as easy as going from the 3.5mm out to splitting it to the speakers, that would be great and I can do that. If i need to get a small amp and wire it in between the phone and car speakers I can do that too. Any ideas, I'd be more that happy to hear them.
If there is a better forum to pose this question, let me know. Otherwise I appreciate you time for reading such a long post and any feed back you may have.
Thank you.
Rusty
I would say get a cheap radio from wal mart,(that has a line n for ipod or something with 3.5mm) hook it straight n to ur phone, at least that way u wont fry anything on ur pretty new phone. (No pun intended, i played with one yesterday they are gorgeous)

You could get a four channel amp, nothing more than 50 watts per channel, then go from 3.5 to rca, then get 2 Y RCA cables (female to males) and wire that up, but buying a head unit would be the best thing

cut off head unit's foreign connector?

went into a local car stereo shop to have my head unit installed (Joying 7" 1024x600 RK3188) and they didn't recognize the unit's male harness (?) connector (see attached photos). They say it's most likely to connect to a Chinese car and they will have to cut it off and splice the wires to an American car harness (PAC C2R-CHY4 harness for '07 Chrysler 300). Is this correct?? I was thinking of installing the head unit myself (since they wanted to charge me too much), wasn't sure if I actually do have to cut it off.
Any kind of insight is appreciated.

That's a standard DIN connector - if a car stereo shop doesn't recognize that, RUN AWAY, they're not very good!
If you don't want to cut the end off, a Scosche VW01RB should plug right in.

LMFAO! Good point! I found the Metra version (71-1784) and ordered that off Amazon since it can get here in 2 days.

I agree with mike.s. That's something pretty much every installer should know. Just as an FYI, I had mine installed on a Ford Explorer and didn't have to cut anything.

Hmmm... now I'm confused. Everywhere online refers to this connector as for VW vehicles, but you put this in a Ford Explorer without that reverse harness?

Well, I didn't do the installation (I paid a professional installer to do it) but I do remember the connector being the same as the one on the picture. For accuracy's sake, this is the actual headunit I got:
http://www.amazon.com/Pumpkin-Recei...25&sr=8-6&keywords=pumpkin+android+car+stereo
Yup, its the same. If you don't mind me asking, how much did you end up paying for installation? I went to a couple of installers and they wanted to charge me extra because they needed to customize the dash kit to fit the oversized head unit ($480+ at one shop and then $700+ at another shop... that second shop wanted to charge me $170 for my car's CANBUS harness even though it's $61 on Amazon, SMFH!)

Im in the Dominican Republic so what I paid over here will have no relation to the prices over there, but i've lived in the US in the past and it looks to me like they're trying to rip you off with those prices. It's definitely not worth it if you're going to pay more for installation than you paid for the actual headunit.
Just for the sake of information, I ended up paying the equivalent of about $150.00 dollars for installation, but it wasn't just the stereo. I had recently bought the Ford Explorer and I had a full sound system in my previous car that I wanted to have transfered over to the Explorer so that price was to remove the 4 speakers, amp and subwoofers from the old car, install the original speakers on it (I had kept them in a box for this exact situation), replace the Explorer's speakers for the ones I had, install the amp and subwoofers, install the back up camera (that I also purchased) AND installing the headunit.
LOL! If only I was still in NYC - I would of got a good deal like that in the heights or Bx.

kinda the same question (sorry) just a different car. I have a 2011 Hyundai sonata. the radio I have has this same wiring harness. will it work in my car as well if I get the metra/scosche wiring harness adapter. or would I need to get something else. or it wont work at all. or can it just be hard wired. thanks for the help in advanced.

I actually have a 2011 GLS. You need the Metra wiring harness to keep from destroying your factory wires. You just wire up the harness and then you connect the harness to the OEM slots. You do have to cut off the standard connector head unless you plan on selling the radio later, there is no good reason to keep it.

Heads up... the memory/constant power and ACC wires/pins were swapped on my head unit's harness connector. Not sure if that is normal or a mistake with these things. Watch out for that

Just note the wiring diagram from your unit and then the reverse harness (whose wires are most likely labeled). If there's differences, wire accordingly - you're just going to have to think on your feet.

Hi,if you want to do wire modification because the harness is difference to your car !
you can use a multimeter. measure the voltage of your car to make connection .permanent +12V power wire to the Yellow wire on Joying ISO plug ,ignition +12V to the Red wire on Joying ISO plug .
and then connect the Black wire on the Joying ISO plug to GND ,the unit should power on .
the rest is connect the speaker cables .
Good luck

Le Max 2 X820 USB Audio adapter quality concerns

I've been eyeing the Le Max 2 X820 for a few months now and I think it's a great deal but the implementation of the 3.5mm headphone jack always makes me rethink. For anyone out there who owns this phone, I have two major questions that always cause me to rethink my purchase decision.
1. How snug is the audio adapter? Headphone jacks give a much more snug connection to the device than the USB-C jack in every phone that I have ever used. The fact that I'll be pulling out the USB audio adapter hundreds if not thousands of times in my ownership of the device really makes me worry that it'll become so loose with mechanical stress that it'll eventually just lose all grip and fall out with even the lightest of pulls.
2. I hear people make claims like "the audio quality is out of this world" or "this is the smartphone for audiophiles." Do those claims have any substance? I have a DAC at home for when I want a dedicated music listening experience and I find it hard to believe that a digital signal running through a low voltage power source could perform anywhere near the quality of a dedicated DAC. What exactly does CDLA do? Allow a lossless passthrough of your music to the USB digital signal? Does it serve as a DAC?
Thanks for taking the time to read this.
The USB adapter is very snug on mine - it is actually quite hard to pull it out even when you want to. Sound through the adapter with a good pair of headphones is decent. I have been playing lossless CD rips and they sound great, especially with the Dolby Atmos dsp. CDLA is only a thing if you buy the Leeco earbuds (I have just ordered a pair from Gearbest for about £10 in a flash sale). Basically it just sends the music digitally rather than converting to analogue on board. The earbuds have a 24-bit hifi audio decoder chip embedded in the usb plug.

I see.
So the USB adapter doesn't do any processing and just serves as an analogue pass-through and the DSP is built right into the device. So I can expect pretty much the same audio quality as any other phone with a headphone jack unless I use the CDLA certified earbuds.
The standard 3.5mm jack isn't exactly a pricey component. Makes me wonder why it was removed in the first place. It's not like the device's selling point is its slimness.
Thanks for the info. :good:
Yes, as far as I know the adapter is just a pass through and doesn't contain an audio chip. The fact you can buy them for just $1 or $2 online would seem to confirm that.

Hello. The socked for 3.5 mm jack does not seem to be, but is the component that takes pretty much place inside the phone. I have lately disassembled my previous phone and realized that.

The thing is, analogue audio signals over the short length of cable on headphones are already basically 'lossless' so CLDA doesn't really have any benefit apart from the fact the DAC is external from the device so the headphone manufacturer may implement a better one than LeEco would have otherwise. That's it.

I agree. Losing the headphone jack is retarded. They could have just put the 24-bit chip from the earbuds in the phone and had a normal 3.5mm jack (it's not like the phone is very thin or waterproof). I would never have got a phone without it by choice, but for me it was a compromise I was prepared to put up with to get a high spec phone at a low price.
Regarding the adapter, mine is already starting to suffer from cable failure at the point where the cable joins the USB jack. Luckily they are very cheap to replace - I just ordered a 10 pack (not LeEco ones) from AliExpress for just $7.

For the price I can put up with the adapter that's for sure. Hopefully we see some nice 3rd party ones with better DACs in them.
Do the iPhone 7 users complain about the same problem? I personally don't care as long as the USB-C to 3.5 mm adapter works.
I think the rationale to lose the headphone jack is untenable on all levels. Not having the option to listen to music through your headphones while having your device plugged into wall power is something I won't ever understand. We're not at a point where most consumers own Bluetooth headsets yet and wireless charging is still limited to trickle power.
I don't know about iPhone users but maybe they just have a higher tolerance to retardation?
I lost the one which came with my phone, so I ordered some of the cheap replacements. I haven't been impressed so far. I'd happily pay more for one which had a high quality Wolfson or similar DAC but I haven't been able to find one.
I bought cheap USB C dongle and the sound was absolutely awful, which makes me think I may have been mistaken in thinking the LeEco adapter (which has very good sound) is just a pass-through. Maybe it does have some kind of DAC and amp in it.
Hi,
I read an Italian review that complained about the incompatibility of different otg adapters with the phone.
Can the same be said for the 3.5mm adapters? Any experiences on that?
Thank you
When i bought the phone i also bought 3 extra adapters incase I lose one or need to use different earbuds. They all sound the same because its only passthrough. But the ones I bought extra are much better quality.

Exact opposite of my experience. The original LeEco adapter and another LeEco one I bought were both great. Non-LeEco ones I bought sound terrible. Like, really unusably awful.
I bought some cheap, generic USB-C to 3.5mm and the audio quality was very strange in a bad way. They all sound bad. I've been using a small Bluetooth receiver for a few months now and it works great, but I'd still rather plug into phone.
If you want a high quality DAC solution, the Creative E3 would be good. I'm using some 'Vital' adapter I got on Amazon for £10. Pretty good for the price
Anyone know where we can buy an official adapter?

AliExpress. The same one as the one the phone comes with costs about $3
i would say the sound is okay with the one came with the phone, nothing more nothing less. Also there r enough cheap and good bluetooth earbuds!
I wonder if it's theoretically possible to use the DAC from the original earbuds to make a universal adapter for any 3.5 earbuds? Like just cut the wire and connect it to the 3.5-jack Mother. Because I'm having hybrid multi-driver earbuds with 3.5 and don't want any other for now.
Does anyone know what exactly DAC is used in LeEco earbuds?
The LeEco CDLA earbuds sound pretty good, but they have the same problems (but magnified) as the apple buds they clearly mimic in appearance - damn things refuse to stay in your ears, and the cables are really weak and flimsy. I haven't used mine all that much but they are already starting​ to fall to bits

Decent Android Head Unit for Seat Ibizia

Hi all,
I bought one of these a while back.
http://www.ebay.co.uk/itm/7-HD-Car-...629297?hash=item1a19100271:g:TpUAAOSwauJZeGBS
The damn thing was so slow I took it back and got my money back. I really want a decent head unit for my car which has enough power behind it to just not be slow and laggy like the one above was. It does not have to be made specifically for my car as I can buy the double-din adapter fascia anyway.
Any suggestions?
