The Moondrop MIAD 01 is one of the most distinctive Android devices of 2024 thus far. It has a 4.4mm headphone jack to go with the more conventional 3.5mm type. Furthermore, it seems it might be as appealing to teardown enthusiasts as well as audiophiles, and may, therefore, also be easier to repair than most modern smartphones.

    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.

      Every phone can have two batteries if you just get a battery pack.

      Unfortunately making the battery removable will make the phone considerably thicker and probably easier to break which is not what most of the users want

        The Galaxy S5 was the last of the mainline series to have a removable battery, and was thinner than the S9 which came out four years later. It also had a pretty good water resistance rating.

        Any “downsides” to a replaceable battery are a myth.

          I will say my Fairphone is a good bit thicker than my work Iphone but honestly it’s not a significant downside for me. The weight is a bigger deal but still not worth the trade-off for a phone I can be confident I can repair myself

            I’m assuming you must be referring to modern phones here right? I never needed a case on my phone until we started getting into S8 territory when phones became incredibly flimsy and fragile. My Note 4 was plastic and aluminum and survived tons of drops. Same with the LG V20 I replaced it with. New phones are required to have a bulky case added on, which defeats the purpose of making them thin and using glass construction. Also modern phones are way thicker than the older phones with replaceable batteries even without a case on them.

        Iirc, removeable batteries make phones harder to break. If you drop them, the back cover and battery come off, reducing the shock on the display.

        • @GolfNovemberUniform@lemmy.ml
          0•8 months ago

          Breaking a modern screen by dropping the phone on a flat surface is not that easy. What can break more often is the electrical circuit between the battery and the phone (causing it to force shutdown that can lead to potential software instabilities), the back cover and sometimes the display flat cable thing

        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.

        • @WaterWaiver@aussie.zoneEnglish
          4•8 months ago

          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.

          • 𝕸𝖔𝖘𝖘English
            1•8 months ago

            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!

            • @WaterWaiver@aussie.zoneEnglish
              3•8 months ago

              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.

                I was going off the few pages I read, including the one I linked. I’m far from an expert in this realm, so, really, I don’t have any substantial argument for or against what either of us are saying. However, filmography, and the related foley artistry, has always intrigued, and I have learned from experience the differences between using a standard jack and an XLR, and I can say that the sound is vastly cleaner with XLR (at least on a set). The secondary jack on this phone seems to be to XLR what USB-microB is to USB-A (again, going off what I’ve read). You do make a lot of sense, though, in your posts, so I may be flat wrong here haha

                  Your experiences were correct, don’t doubt them. That would have been ground-referenced equipment, ie plugged into wires that eventually join a wall. RF interference would interact with that quite differently, unbal vs bal would be quite different.

    • @Thteven@lemmy.world
      2•8 months ago

      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.

  • @njaard@lemmy.world

    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.

        Hahaha!! I wish! Actually, I have old equipment that only takes the 6.35mm TS (and a couple TRS) connectors, and I don’t like adaptors, as they almost always noticeably reduce audio quality.

          • 𝕸𝖔𝖘𝖘English
            0•8 months ago

            Yeah. Maybe I just bought the super cheap ones? Not sure. I ended up getting a 3.5 to 6.35 cable, and haven’t had a problem since.

              2•8 months ago

              That’s really weird o.o The adapters should just be metal and plastic, same as the cables.

              Maybe they have a really weak connection internally, ie high resistance? This might lead to both lower volume in the headphones and (in some circumstances) higher noise, especially if it’s an unstable resistor.

              I recommend starting a shelf of cursed items :)

                  This could end up competitive.

                  Invite people to your house, give them a tour and briefly mention the shelf before scurrying them on. Watch their faces contort but don’t give them the opportunity to ask any questions.

                  EDIT: I have a vague guess at what could have gone wrong with your adaptor. It might have had OK L and R contacts but a broken G contact. You would then hear the difference between the L and R channels, which most often sounds like garbage. Music would be weird (entire instruments/vocals disappear) and mono audio would be silent or near-silent (so you’ll have to turn it up a lot and will hear noise).

                The quality of random no-brand audio cables, connectors, adapters etc. tends to be right-out atrocious. There’s technically going to be metal in there but that “nice”, thick headphone cable that came with those cheap headphones (and even some decent ones, like AKG K240s) is going to consist mostly of insulation, not conductors. Plastic is quite a bit cheaper than copper.

                You can get ok jack adapters for 80ct but honestly I wouldn’t trust that thing if I didn’t trust Thomann. Usually I’d be looking for Rean when wanting a cheap one but they’re apparently not in stock. And I kinda doubt Neutrik or Hicon even produce them if you’re spending five bucks on a 3.5mm jack you’re not using adapters, you’re soldering the exact cable you need.

                Oh. Back to resistance: Doesn’t really matter audio quality doesn’t care it’s still the same AC signal just with less amplitude which you can fix with the volume knob, You’re looking for impedance and material boundaries have a habit of being bad for it, as well as signal quality as parts of the signal will propagate through the boundary and parts will reflect. For more information ask an actual electrical engineer I merely wrote an A in a course I had to take and can tell the hot end of a soldering iron from the cold one (it’s the one with the cable).

                  Only for ideal resistors.

                  Resistors are noise sources. Intentional resistors tend not to be too bad (and probably won’t be heard in this situation unless you have super-high-impedance headphones, perhaps 10’s of K), but unintentional resistors (eg corroded unstable metal contacts inside a plastic part) can be atrocious.

                  A few things to add to this:

                  (1) If your resistor acts even slightly like a diode then you will encounter partially rectified RF signals (more noise yay). Metal oxides between metals can do this, eg if the connector has crimped two badly-plated bits of metal together.

                  (2) Plasticisers in some plastics can leak out, causing corrosion on unseen internal metal parts.

                  (Of course linking all of this together is just conjecture, the causes of Moss’ bad adaptors might be something completely different)

    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.

    • @Pilferjinx@lemmy.world

      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.

        3•8 months ago

        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).
