  • There's lots of money to be made by inserting a hardware back door in your product then later disclosing it as an unfixable vulnerability and force your customers to buy new hardware which has the same but different backdoor. Repeat.

    Thanks, I hate it. Vulnerable to your competitor red teaming it tho...

  • I mean, there were legitimate technical issues with the standard, especially on smartphones, which is where they really got pushed out. Most other devices do have headphones jacks. If I get a laptop, it's probably got a headphones jack. Radios will have headphones jacks. Get a mixer, it's got a headphones jack. I don't think that the standard is going to vanish anytime soon in general.

    I like headphones jacks. I have a ton of 1/8" and 1/4" devices and headphones that I happily use. But they weren't doing it for no reason.

    • From what I've read, the big, driving one that drove them out on smartphones was that the jack just takes up a lot more physical space in the phone than USB-C or Bluetooth. I'd rather just have a thicker phone, but a lot of people don't, and if you're going all over the phone trying to figure out what to eject to buy more space, that's gonna be a big target. For people who do want a jack on smartphones, which invariably have USB-C, you can get a similar effect to having a headphones jack by just leaving a small USB-C audio interface with a headphones jack on the end of your headphones (one with a passthrough USB-C port if you also want to use a USB-C port for other things).

    • A second issue was that the standard didn't have a way to provide power (there was a now-dead extension from many years back that is now dead, IIRC for MD players, that let a small amount of power be provided with an extra ring). That didn't matter for a long time, as long as your device could put out a strong enough signal to drive headphones of whatever impedance you had. But ANC has started to become popular now, and you need power for ANC. This is really the first time I think that there's a solid reason to want to power headphones.

    • The connection got shorted when plugging things in and out, which could result in loud sound on the membrane.

    • USB-C is designed so that the springy tensioning stuff that's there to keep the connection solid is on the (cheap, easy to replace) cord rather than the (expensive, hard to replace) device; I understand from past reading that this was a major reason that micro-USB replaced mini-USB. Instead of your device wearing out, the cord wears out. Not as much of an issue for headphones as mini-USB, but I think that it's probably fair to say that it's desirable to have the tensioning on the cord side.

    • On USB-C, the right part breaks. One irritation I have with USB-C is that it is...kind of flimsy. Like, it doesn't require that much force pushing on a plug sideways to damage a plug. However --- and I don't know if this was a design goal for USB-C, though I suspect it was --- my experience has been that if that happens, it's the plug on the (cheap, easy to replace) cord that gets damaged, not the device. I have a television with a headphones jack that I destroyed by tripping over a headphones cord once, because the headphones jack was nice and durable and let me tear components inside the television off. I've damaged several USB-C cables, but I've never damaged the device they're connected to while doing so.

    On an interesting note, the standard is extremely old, probably one of the oldest data standards in general use today; the 1/4" mono standard was from phone switchboards in the 1800s.

    EDIT: Also, one other perk of using USB-C instead of a built-in headphones jack on a smartphone is that if the DAC on your phone sucks, going the USB-C-audio-interface route means that you can use a different DAC. Can't really change the internal DAC. I don't know about other people, but last phone I had that did have an audio jack would let through a "wub wub wub" sound when I was charging it on USB off my car's 12V cigarette lighter adapter --- dirty power, but USB power is often really dirty. Was really obnoxious when feeding my car's stereo via its AUX port. That's very much fixable by putting some filtering on the DAC's power supply, maybe needs a capacitor on the thing, but the phone manufacturer didn't do it, maybe to save space or money. That's not something that I can go fix. I eventually worked around it by getting a battery-powered Bluetooth receiver that had a 1/8" headphones jack, cutting the phone's DAC out of the equation. The phone's internal DAC worked fine when the phone wasn't charging, but I wanted to have the phone plugged in for navigation stuff when I was driving.

    Honestly I'd be happy with a phone sporting two USB C ports, one centered and one off to the side where the headphone jack used to be, both fully functional.

    I know someone who works somewhat high up at Apple and he told me another reason was that they really wanted to improve the water proofing.

  • I never have it enabled unless I am in the car driving and need driving directions or listening to music/podcasts. I prefer wired headphones, but manufacturers are making that difficult.

    Because they can't sell you more Bluetooth crap if they give you a choice.

    Stop buying no-Jack phones.

    Sounds like the attack scenario is very sophisticated and targeted, and only works within the range of Bluetooth low energy (BLE) connectivity, so 10-15 meters under best circumstances. At that point they might as well eavesdrop on my calls in person.

    It’s strange to think about how complicit the public has become with this. You mean to tell me that 185 separate connections to other companies are required for me to… read an article?

  • I know someone who works somewhat high up at Apple and he told me another reason was that they really wanted to improve the water proofing.

    That's just gaslighting. Other phones had audio jacks, water protection, and you didn't have to hold them funny.

    My bro is a huge apple kool-aid guy and he spouts their dogma word-for-word.

    Well yeah, they have to hoard your advertising data somehow. How else can they advertise things that you don't need to buy?

  • you can just permanently connect your headphones to your dongle

    No. Fuck that. My PC has a headphone jack, and I use it. I don't have a bunch of extra USB-C ports on the front of my computer. Modern phones have plenty of spaces for headphone jacks. They could put it there, they just don't want to.

    I used a USB connection through my KVM to connect to one computer or the next. But it's just something to plug my headphones into the 3.5mm jack.

    Since it never gets unplugged, it doesn't get lost; unlike all those "just have this snowflake dongle in one of all of your stuff so it can get lost monthly and you can buy another" people.

    Again: my startac 7800 had a jack and it was tiny. Apple and Samsung have NO EXCUSE.

  • Or public transit. Or public parks. Or grocery stores.

    Yesss. Find that sploit and please let it never be fixable. I didn't download a copy of The Wheels On The Bus for nothing.

    Instead of hacking Bluetooth, sounds more effective to be an "advertising partner".

    So glad I use wired earbuds and refused to buy a phone that didn't support them.

    Define AGI, because recently the definition is shifting down to match LLM. In fact we can say we achieved AGI now because we have machine that answers questions. The problem will be when the number of questions will start shrinking not because of number of problems but number of people that understand those problems. That is what is happening now. Don't believe me, read the statistics about age and workforce. Now put it into urgent need to something to replace those people. After that think what will happen when all those attempts fail.

    My understanding is that if they've lasted at least a month and haven't died on you, you probably got a "good" batch and what you have now will be what it stays as for the most part, but a fair number of gulikits just sort of crap out at the 1-2 mo mark. So heads up on that.

    This is a weirdly aggressive take without considering variables. Almost petulant seeming. 6” readers are relatively cheap no matter the brand, but cost goes up with size. $250 to $300 is what a 7.8” or 8” reader costs, but there’s not a single one I know of at 6” at that price. There’s 10” and 13” models. Are you saying they should cost the same as a Kindle? Not to mention, regarding Kindle, Amazon spent years building the brand but selling either at cost or possibly even taking a loss on the devices as they make money on the book sales. Companies who can’t do that tend to charge more. Lastly, it’s not “feature creep” to improve the devices over time, many changes are quality of life. Larger displays for those that want them. Frontlit displays, and later the addition of warm lighting. Displays essentially doubled their resolution allowing for crisper fonts and custom fonts to render well. Higher contrast displays with darker blacks for text. More recently color displays as an option. This is all progress, but it’s not free. Also, inflation is a thing and generally happens at a rate of 2% to 3% annually or thereabouts during “normal” times, and we’ve hardly been living in normal times over the last decade and a half.

    The new Pebble watches look interesting. Relatively basic, but long battery life (they promise) and open-source operating system.
