Why not just link to the repo directly? That post only has one comment.

Here’s the repo (to save everyone a click):

You'd think Sony would have learned from the PSN debacle, but alas...

Now I need to setup to check if my headphones are still vulnerable...

What about B bluetooth keyboards and touchid

This is just a chip with debug mode left on and does not allow anyone to hijack audio stream or anything interesting. (Just in case anyone’s checking the comments because they don’t want to watch a long ass video and they notice all the comments are essentially off topic)

checking my understanding: this vuln is in the firmware for specific airoha chipsets; e.g. if a bluetooth device is listed as using a qualcomm chipset then it's unaffected by this specific vuln?

... though I wouldn't be surprised if we see a burst of similar disclosures for other manufacturers in the next year or so

Shame on Airoha. Terrible security pracices.

Ah yes, the removal of headphone jacks, the gift that keeps on giving

Funny that there were always some people here pushing bt audio as "the future", whom I can only assume were the technically shallow but very opinionated people that would die on the smallest technical hills

I'd assume that most people wouldn't want to get back to wired headphones.

Transition period was definitely rough, but nowadays bluetooth headphones are substantially better than they were in the past, and it's quite freeing to not have to deal with wires.

There are definitely benefits to wired headphones, such as better audio quality and no battery life to worry about, but for those cases there are USB-C DACs.

I still use wired headphones. This bluetooth vulnerability makes me laugh.

Brand new devices' batteries are awesome but wear off and need to be changed at some point, if A) the device is designed to let you do that and B) the battery is still in production.

You don't really own a wireless headphone. You can see it as a rent, or an ownership that loose its capability when in use.

It's not like wired earbuds/headphones are invincible either. I've had a few wired ones lost due to cable damage, which constitutes more casualties than my wireless inventory, including noticeable charge loss. Of course, there are a lot more cheap wired options with replaceable cables now, thanks to Moondrop and gang.

I really wish the debate was more than jack vs Bluetooth, and more wired fans would consider supporting devices with multiple USB-C ports. Yeah, Sony still puts a jack on Xperias, but most audiophiles note that it's driven by Snapdragon's mediocre integrated DAC, possibly because Sony doesn't want it to compete with Walkmans. Yeah, Valve puts a jack on the Steam Deck, but SD OLED's jack has interference issues that users need to fix with electrical tape or loosening screws. If these devices had two USB ports, then it would be easy to use a better DAC with no interference issues (while also charging with a cable attached to the other port). Having a second USB port would increase device life, and tie wired earbuds/headphones to a more durable standard that's actively developed and backed by legislation. We know this is possible for phones because ASUS ROG Phone has 2 USB ports.

The word you are looking for is not “rent” but depreciation.

Thanks god the headphone jacks died in smartphones.

I switched to USB-C soundcard cables which are dirt cheap and survive much much more plug-unplug-cycles. They easily can be replaced.

The epidemic of people not wearing headphones has been directly caused by the lack of headphone jacks
Findecanor 4 hours ago|||
I find that people speaking very loudly into their wireless headsets wherever they are and whomever they are with is a bigger nuisance.

When you speak to someone in person, you'd adjust the volume of your voice to the room and the recipient without thinking about doing it. The engineers who built the analogue phone system were aware of this effect, and made it so that you heard yourself in the handset's speaker. The engineers who designed the cell phone standards decided to ignore this so they could do more echo-cancellation.

It is not a big problem when people are speaking into a slate-shaped cell phone, but when people wear headphones that attenuates their own voice, they hear themselves less and speak extra loudly to compensate.

A couple days ago there was a bit of a conversation about this, you might find it interesting. It seems this feeling (to the point of calling it an "epidemic"!) might be caused by the known bias of thinking that earlier times were better:

LOL. People not using headphones in public are narcissistic a-holes, but they’ve been doing it since *long* before headphone jacks went missing from smartphones.

It’s even noted as a problem in the beloved, acclaimed piece of cinema - Star Trek IV : The Voyage Home.
