    I was hoping this would allow me to take over Bluetooth speakers that people use while skiing and replace their music with a PSA about how no one wants to hear their music

  • Hum...

    Double post

  • and also why corporations didn't want them.

    Exactly! So they can spy on us more!

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

  • 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.

    I lot of great points here, I would be on aboard if phone 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.

  • 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.

    It's BLE - Bluetooth Low Energy.

    Basically devices with BLE can listen for a wake-up command and turn on, similar to the "magic packet" of wake on Ethernet.

    Super convenient for "find my device" applications, also nice to be able to connect and activate the device without having to press a power button like a peasant.

    It also means that most devices with BLE end up flat within a month. I had a speaker with BLE and had to deliberately download a much older version of the Android partner app to turn it off, as they dropped the option to do so in later versions for "convenience". With BLE on it would be flat in about 6 weeks regardless of whether I'd used it or not , which really ruined ad-hoc usage for me.

    That's great and all but I'm not switching to Bluetooth headphones and I'm definitely not going to fiddle around with dongles every time I switch between listening on my phone and my PC. Phones are gigantic anyways; let my have my headphone jack. I don't think it's a coincidence that all these smartphone manufacturers that ditched the old standard will happily sell you shiny expensive disposable wireless earbuds.

    I think this is a case where the corporations were telling people what they wanted rather than people really asking for thinner phones. Same thing with bezels, I don't know anyone who asked for the screen to go all the way to the edge (or worse, curve around onto the sides). Apple and Samsung said 'this is what people want' when in fact it was what their marketing department wanted because they wouldn't be able to sell the iGalaxy N+1 if it was slightly thicker or heavier than the iGalaxy N.

    as someone has been fiddling with dongles for years, it's not that bad, and you can just permanently connect your headphones to your dongle. the apple dongle is excellent and beyond enough for iems and a lot of headphones. I personally have one dongle + iems for my phone and another dongle + headphones for my PC, and that setup works really well for me. You might want to consider it. Otherwise, those big beefy Bluetooth headphones might be semi-repairable, and there are of course also Fairphone Bluetooth earbuds that are apparently fairly repairable (though I know nothing about those). At least you can replace the batteries and the ear tips or pads, and that's usually enough to last you a decade with these things.

    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.

    phones are already very full and dense, and a headphone jack is a very large component. plus, the Bluetooth is simply part of the small SoC, it's a microscopic size. That doesn't mean I prefer Bluetooth, but it makes some sense.

    TD Cowen (which is basically the US arm of one of the largest Canadian investment banks) did an extensive report on the state of AI investment. What they found was that despite all their big claims about the future of AI, Microsoft were quietly allowing letters of intent for billions of dollars worth of new compute capacity to expire. Basically, scrapping future plans for expansion, but in a way that's not showy and doesn't require any kind of big announcement. The equivalent of promising to be at the party and then just not showing up. Not long after this reporting came out, it got confirmed by Microsoft, and not long after it came out that Amazon was doing the same thing. Ed Zitron has a really good write up on it; https://www.wheresyoured.at/power-cut/ Amazon isn't the big surprise, they've always been the most cautious of the big players on the whole AI thing. Microsoft on the other hand are very much trying to play things both ways. They know AI is fucked, which is why they're scaling back, but they've also invested a lot of money into their OpenAI partnership so now they have to justify that expenditure which means convincing investors that consumers absolutely love their AI products and are desparate for more. As always, follow the money. Stuff like the three mile island thing is mostly just applying for permits and so on at this point. Relatively small investments. As soon as it comes to big money hitting the table, they're pulling back. That's how you know how they really feel.
