The Bluetooth chipset installed in popular models from major manufacturers is vulnerable. Hackers could use it to initiate calls and eavesdrop on devices.

Wired headphones stay winning
… and this is why I don’t use bluetooth on anything.
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.

Alright now how do I test this out
And this is why people wanted headphone jacks… and also why corporations didn’t want them.
I’m not really sure that is the reason. I’m not saying I would put it past them, just that I really don’t think it’s necessary. Smart phone manufacturers have a million other ways they could spy on you if they wanted to. The U.S. Government already has the ability to know each and every thing you do on your phone, even if you never use Bluetooth. I think it’s greed pure and simple. It probably cost’s them a few pennies to add a physical jack and most people would lose their shit if a phone came out without Bluetooth capabilities, so they save those couple of pennies and put them into their greedy ass pockets.
That being said I have never bought a phone without one and never will as long as I have a choice. I do love my wireless headset though but I am also not too worried about being spied on (yet).
I’m 100% convinced that is why they stopped making batteries user replaceable though. In 2019 Edward Snowden did an interview with Wired magazine where he made the interviewer remove the battery from his phone as a condition of the interview. He explained that the U.S. Government can make it seem as if your device had been ‘powered down’ when in fact they can still listen to your conversations and transmit them back to the CIA or whatever other spooks that want to listen in. Shortly after than almost all manufactures stopped allowing you to remove the battery. Coincidence?
My current phone doesn’t have a removable battery, because I literally couldn’t find one in my price range that allowed you to do so.
The best advice if you don’t want to be spied on is not to use a smartphone altogether or just do whatever you want to be kept secret away from the phone at the very least. Buy a Faraday bag and keep your phone in there if that’s not an option.
Eh, you’re assigning an awful lot of malice with no real reason. A smartphone manufacturer already has access to the kind of data exposed in this attack, regardless of whether the headphones were hooked up with wires or bluetooth.
Samsung, Apple, Xaomi, Huwaei or whoever else doesn’t need some stupid BT vulnerability to know what attached devices like headphone are up too. They already have root level access to the phones hardware.
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 wouldn’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 the USB-C port for charging).
-
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, 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 avoidable for the manufacturer 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 (battery hungry) navigation stuff when I was driving.
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.
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’d rather just have a thicker phone, but a lot of people wouldn’t
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.
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.
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.
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.
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.
Great post, thank you.
I lot of great points here, I would be on aboard if phone therefore had two USB-C ports as standard
-
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.
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.
Double post
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…
They said I was mad when they removed the headphone jack - well who’s mad now??! AHAHahahahaaaaaaahhhhcrap it’s me.
I’m still mad. Fuckers.
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.
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.
Every spy in my vicinity is going to be dancing to The Meters - Cissy Strut.
Awwwwwwwwwwwwww YAH
Shitty Beatles & the meters… I’ll follow you anywhere
A fine choice though.
So how do you determine if your headphones have the vulnerable chip in them?
The flaws, discovered by German cybersecurity firm ERNW and first reported by Heise Online, affect dozens of headphone models from brands such as Sony, JBL, Bose, and Marshall, with no comprehensive firmware fixes available yet.
- Sony WH-1000XM4/5/6, WF-1000XM3/4/5, LinkBuds S, ULT Wear, CH-720N, C500, C510-GFP, XB910N
- Marshall ACTON III, MAJOR V, MINOR IV, MOTIF II, STANMORE III, WOBURN III
- JBL Live Buds 3, Endurance Race 2
- Jabra Elite 8 Active
- Bose QuietComfort Earbuds
- Beyerdynamic Amiron 300
- Jlab Epic Air Sport ANC
- Teufel Airy TWS 2
- MoerLabs EchoBeatz
- Xiaomi Redmi Buds 5 Pro
- earisMax Bluetooth Auracast Sender
ERNW emphasizes that this is only a partial list.
Sony WH-1000XM4/5/6
I don’t have one of those, but they’re pretty popular as headphones with good ANC.
Jlab Epic Air Sport ANC
I do have those, though.
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 thise chips.
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.
According to the article, headphones using a Bluetooth SoC manufactured by Airoha may be vulnerable. So, need to find if your headphones use their SoC.
You will need to do some research on your headphones, I guess.
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
Most annoying people on the mountain
Or public transit. Or public parks. Or grocery stores.
My Redmi buds 5 had a firmware update available for me in the app. It could be an older one though, their patch notes suck and don’t even say the date. v4.3.8.8
This is why I chose to get a Corsair Virtuoso, which has a removable microphone.
