I just picked up a G2 to replace my broken HTC One M7.
I love the phone but when I connect it to my car stereo using an Aux cable, I hear hissing and interference during quiet portions of music. I do not hear it using headphones. The cable is high quality and with my HTC the sound was flat out amazing, pure clear output with additional noise. I connected my wife's Iphone 5s and my daughters Galaxy S4 using the cable and they sounded fine also.
Any thoughts or ideas on this? Really mars an otherwise fantastic phone experience....
In terms of 1. the sound output on the headphone jack (sound quality, output volume). How does it compare to other phones that you have owned? I'm especially interested in how it compares the iphones with the best headphone sound quality such as the iphone 4 or the iphone 5s. I'm aware that the MXPE, as with the iphones, does not have native hi def audio support as it only supports up to 16-bit/48KHz natively (source: www dot whathificom/motorola/moto-x-style/review).
and 2. build quality (is there an inner ring made of metal inside the jack ,completely flush with the metal contact part of the plug, to stabilize the heaphone plug?). The design of the headphone jack, placed on a slended edge, is such that some headphone plugs with larger heads are not going to be able be completely flush with the jack when plugged in, as compared to the iphone 4. In these cases, is the headphone plug stable enough when plugged in such that it will withstand prolonged usage? Has anyone had any issue with similarly designed headphone plugs on the moto x 2014 and the nexus 6 after prolonged usage?

I find the quality of the headphone jack quite good. My previous phones are Samsung Galaxy S3 and Nexus 5.
The sound quality is good imho, good loudness and no need to install any software to tweak the sound.
As for the metal jack, the headphones are stable enough when plugged in. I don't have the feeling that there will be issues with prolonged usage.
I also found both the audio and build quality of the jack quite good.
+1 from me also. I have a pair of Sony headphones that come with my Z3, the sound quality is on par with or better than any recent phone I've used, much better than the S6 for sure.

I didn't like the sound. I used the equalizer to amplify the bass sound. Anyway, my reference was a in-earphone, which have better bass reprodution.

The build quality is ok. The earphones are quite comfortable, but the cord is thin.
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
After using ear buds, the speakers quit working! Ear buds still work. But no sound from speakers after removing earbuds.
One speaker died.
I have 2017 hd 8 and one speaker died,called Amazon.
They sent replacement.
NEED to replace w better or stock speakers. Looking for replacements. Have not found.
Is there any serviceable parts?
I have had the problem you speak of and I reinstalled headphones and it returned to normal. Now I'm hesitant on use of port. Gl
