    and also why corporations didn't want them.

    Exactly! So they can spy on us more!

    Sony WH-1000XM4/5/6

    I don't have one of those, but they're pretty popular as headphones with good ANC.

    I do have those, though.

    A fine choice though.

    Even if these attacks seem frightening on paper, the ERNW researchers are reassuring: many conditions must be met to carry out an eavesdropping attack. First and foremost, the attacker(s) must be within range of the Bluetooth short-range radio; an attack via the Internet is not possible. They must also carry out several technical steps without attracting attention. And they must have a reason to eavesdrop on the Bluetooth connection, which, according to the discoverers, is only conceivable for a few target people. For example, celebrities, journalists or diplomats, but also political dissidents and employees in security-critical companies are possible targets.

    I guess they didn’t point this out because it’s kind of obvious, but it sounds like they also have to actually be on to be exploited. So it’s not going to turn on and start listening to you at least. Definitely concerning, but I’m still gonna be listening to my audio books and podcasts with my wireless headphones.

    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.

  • And this is why people wanted headphone jacks... and also why corporations didn't want them.

    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.

    A speaker i have from bose is always on and "sleeping" and can be connected to from the phone no matter what i do, drains the fucking battery and when i want to use it finaly its dead.. wouldnt be surprised if some headphones worked the same..

  • A speaker i have from bose is always on and "sleeping" and can be connected to from the phone no matter what i do, drains the fucking battery and when i want to use it finaly its dead.. wouldnt be surprised if some headphones worked the same..

    It sounds like they have some kind of wake function that it’s always listening for? I don’t think that’s a common feature in headphones just because of the battery drain, but they’re always chucking useless features on electronics so I’m sure some are floating around out there. I doubt it’s something you wouldn’t know about unless they were secondhand, though.

    Damn that's pretty big, hopefully they update and give a final list of affected devices. Not to mention, gotta pray the devices will see software updates to try and mitigate it.

    Yeah. I have the previous version of the WH which seems not affected, but I also have the WF 3 which unfortunately seems to be.

    Many people have sony headphones with those chips.

  • Hum...

    The only time a hacker is going to target you like this is if you're an extremely high value target like a CEO or if you're in the crosshairs of a nation-state. The average hacker isn't going to waste this kind of effort to hack someone with $200 in their bank account and no power over anything or anyone.

    No, the real reason is it saves a few pennies per phone. They can already spy on us through the internal mic.

    A lot of great points here, I would be on aboard if phones therefore had two USB-C ports as standard

  • A speaker i have from bose is always on and "sleeping" and can be connected to from the phone no matter what i do, drains the fucking battery and when i want to use it finaly its dead.. wouldnt be surprised if some headphones worked the same..

    A smart outlet (and running home assistant) will solve that problem.

    [image: 62e40d75-1358-46a4-a7a5-1f08c6afe4dc.jpeg] Palantir had a contract with New Orleans starting around ~2012 to create their predictive policing tech that scans surveillance cameras for very vague details and still misidentifies people. It's very similar to Lavender, the tech they use to identify members of Hamas and attack with drones. This results in misidentified targets ~10% of the time, according to the IDF (likely it's a much higher misidentification rate than 10%). Palantir picked Louisiana over somewhere like San Francisco bc they knew it would be a lot easier to violate rights and privacy here and get away with it. Whatever they decide in New Orleans on Thursday during this Council meeting that nobody cares about, will likely be the first of its kind on the books legal basis to track civilians in the U.S. and allow the federal government to take control over that ability whenever they want. This could also set a precedent for use in other states. Guess who's running the entire country right now, and just gave high ranking army contracts to Palantir employees for "no reason" while they are also receiving a multimillion dollar federal contract to create an insane database on every American and giant data centers are being built all across the country.

    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.
