Dual headphone jack smartphone scores high in new reparability video
(www.notebookcheck.net)
Reminds me of the "therapy spider AI," in Questionable Content.
Dual headphone jacks. You "hear" that, Fairphone‽
Here's specs: https://liliputing.com/moondrop-miad-01-smartphone-with-hifi-audio-features-launches-globally-for-399/
Seems nice. I just wish it had removable battery, like phones used to, so I could carry a spare around, like I used to with Sony Ericsson W200i.
Also dedicated dual SIM + MicroSD instead of hybrid.
Just got an idea, the Galaxy Flip has 2 batteries. Small one, and large one. What if there was a small one built-in, and a larger swappable one. You could then hot-swap the batteries like with some ThinkPads (those with internal + external battery).
Oh look, a "specialty" android device with actual decent specs. Someday something like the Linux phone or fair phone or any of the other "specialty" phones to catch my attention over the years will get it together and do the same lol
Fairphone has a removable battery pack, it's pretty handy.
But no headphone jack.
Awesome another decent phone outside of the big 3 that yet again doesn't support TMobile's bands. Just my luck...

This is a neat explanation of the purpose of the other jack, in case anyone was wondering.
Yes, but it's basically placebo if your headphone cable is of a normal length
I wouldn't say placebo. It's definitely doing something. I would say it's unnecessary in most environments, and probably definitely on a mobile phone. But to lift right out of the article:
You may be wondering if balanced audio is “higher quality” than unbalanced — the answer is no. Balanced cabling doesn't provide a better quality of sound than unbalanced cables. Audio source and the quality of materials in the actual cable's construction determine sound quality more than anything. However, balanced audio does a better job of eliminating noise, should it exist in your signal. In a case where extraneous noise is present, balanced audio will be clearer than unbalanced audio.
I wouldn’t say placebo. It’s definitely doing something.
I would say this is still a placebo. Placebos always still do something. A sugar pill tastes sweet and modifies the sugar levels in your blood. The important questions are validity and effectiveness, not whether or not it does something.
Balanced audio will not eliminate noise in most of the circumstances where a headphone user hears noise. There are far more likely sources (the source file itself, DAC limitations, audio amp limitations, external sound from their environment, etc). It will help in some very specific circumstances, but that's like trying to sell snow chains to all car owners on the planet because you can claim that they improve traction.
If you do work in an environment where changing to balanced headphone signalling helps... why are you working with your head inside an RF hazard zone?
(From page): However, balanced audio does a better job of eliminating noise, should it exist in your signal. In a case where extraneous noise is present
Misleading.
Noise exists in all signals. Balanced audio only "does a better job" in circumstances other than what this product is being sold for. Discussing this at all gives it false merit anyway.
EDIT: Giving this some further thought: balanced and unbalanced signalling is mostly moot when you're an isolated device with one cable attached. From an RF standpoint you're not forming both halves of an antenna (dipole or monopole+ground). Electrically they both look extremely similar in this scenario. Your partially conductive human arms waving around will probably couple to RF noise better than the headphone cable.
Ah. Yes. I see your original meaning. I misunderstood what you had meant.
Balanced will reduce noise (in terms of RF noise, of course) significantly better than unbalanced, but the source of noise does need to be far enough away from the capturing device to not affect it directly and, therefore, be able to be negated by the balanced cable. However, the end user (listening to balanced vs unbalanced signal on a mobile phone) won't be experiencing a difference between the two (IE placebo affect).
Thanks for clarifying!
Balanced will reduce noise (in terms of RF noise, of course) significantly better than unbalanced,
In this situation I don't think it will at all.
I don't think that balanced vs unbalanced is actually electromagnetically that different in this particular configuration (see my edit at the end of above). Things like where the wire is sitting on your body and what pose you are in will probably affect RF noise pickup levels on the headphone wires much more than changing between bal & unbal signalling.
but the source of noise does need to be far enough away from the capturing device to not affect it directly and, therefore, be able to be negated by the balanced cable.
I didn't get into near-field and far-field effects. I'm not sure that it really matters here, but I might be wrong.

The practical reason people use balanced jacks is because they push more power which allows you to use headphones with lower sensitivity. I have a few pairs myself that would benefit from this, they have relatively low ohm ratings so the high impedance setting on my V60 doesn't get triggered when I plug them in and they are very quiet.
Man, this is looking really appealing:
- Headphone jack!
- Great global and US network support
- "Honest" marketing of its cameras (lol!)
- Huge :(
Now the only thing that's missing is if it's reasonably easily rootable, so I'll keep an eye on this phone.
2 headphone jacks is definitely a choice. I wonder if there's at least one use case for it in 2024 though
It's aimed strictly at audiophiles. The extra jack is a 4.4mm jack that's more common in things like DACs.
An example:
https://nobleaudio.com/products/dac-amp-with-4-4mm-pentaconn-output
Pair a phone like this with a pair of Sennheiser's and a bunch of FLAC files and you might have a really good time.
Oh so the jacks are different? Ok then. I thought the other sizes are dead or only used in niche $100k+ equipment
Second sentence:
It has a 4.4mm headphone jack to go with the more conventional 3.5mm type.
4.4mm is for balanced audio output. This audience for this device is audiophiles.
Well idk anything about audiophile stuff. I know I can't afford to even look at such tech lol
You'd be surprised. Plenty of great in ear monitors that are sub $100 and use balanced 4.4mm jacks.
What is an in ear monitor? Is it like a medical device?
It's only a fancy name for speaker/headphones which make them sound more professionally, there's a chance but no guarantee that they are tuned more neutral in sound
Well dang. I'm getting it. I'll sacrifice a decent bit of CPU performance for a phone made with some principles and with the moon audio quality.
Of course it doesn't support band 71, which is the only 5G band I can get at home.
A bit of excessive, I know, but I would love a 6.35mm jack, too.
Personally I only use smartphones with dual XLR output and optical SPDIF.
Hahaha!! And I thought I was being excessive haha!
Kinda wild these weren’t really a thing. A lot of these DAP/DACs were already running Android & many folks don’t like carrying a second phone-sized device (my DAP is small on purpose for this… well & my previous phone didn’t haze microSD for extra storage). Was it something to do with complaince for the cell radios?
The big question mark to me would be if they open source those drivers & what not or make any required apps downloadable & sideloadable. I would make something like this my next device if I knew I could flash LineageOS for microG on it & not, you know, lose all the audio stuff that makes it special. A lot of these Chinese brands haven’t even done the bare minimum GPL v2 compliance of releasing their kernels so we would have to see on that front. The ability to control your software is just as important as repairing your hardware.
Yes. All I want from a phone is to be able to run a custom rom and have decent audio chips. I haven't been able to justify having a dedicated dap because I hate carrying more than is necessary.
This is not so much as an edorsement or recommendation, but you might check out the DAPs by Shanling or Hidiz if you have coin to spare. They use Linux & don’t publish kernel mods, but they do have inexpensive, very small, lightweight options that may fit your needs. I have one & it has a place to have a dedicate device to not chew thru my phone’s battery as well as function as a high-quality USB DAC in scenarios where you don’t have a jack (like my old laptop) or the DAC is horrible (like in my dock for my laptop).
Dual usbc when?
ROG phones have this and a headphone jack.
They also fail the jerry rig durability test. They are very bulky too.
From moondrop?! I have some really cheap iems from them, they're great
I love the phone despite the large size but can't get GPS working in apps
That's ... a pretty significant issue.
I would never be able to go anywhere
That would be a bonus for me. I never use it.
Why, you drive a cab for a living so when you get directions you know exactly how to get there from memory?
No, I do not. It is possible to get around without GPS, has been for millennia. I don't need it, don't want it, if you do that's fine.
