Meanwhile all the phones dropping jack because Apple started it. Official reason is to "waterproof phones"

The most frustrating part is when Apple dropped the jack we laughed at the "courage" bit, Apple's given reasons where already seen as bullshit, Samsung had their finger pointing moment. And it just went on, Apple weathered the critics, the other makers also dropped it, and at some point there was just nowhere to go for anyone still wanted a 3.5 jack with a decent phone.

The jacks are a physical impediment for slim phones. An adapter costs $3 if you still want it. It’s not a bad trade.

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.

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.

3$ adapter will have low quality DAC

> We also demonstrate how a compromised Bluetooth peripheral can be abused to attack paired devices, like smartphones, due to their trust relationship with the peripheral.

Can't watch the video now. But I wonder to what extent they can take over a smartphone? Can they make a headphone look like a keyboard/mouse, for example?

Second question: can the whole problem be remedied by installing a firmware update?

And everyone got mad at OpenBSD for refusing to develop bluetooth. It’s a messy standard and we shouldn’t be surprised that the race to the bottom has left some major gaps.. though Sony WH1000’s are premium tier hardware and they have no real excuses.. I always wondered how people could justify the growth of the bluetooth headphone market in such a way.. Everyone seems to use bluetooth headphones exclusively (in Swed…

Alright, so when is OpenBSD patching out USB support? Such a giant exploit vector.

They also demonstrated how this could be used to silently find out someone’s phone number and then hijack a TFA validation call from an app like WhatsApp to take over their account with no user interaction.

This attack was not silent, it was noisy. They specifically pointed that out in their talk.

Most audiophiles ignore bluetooth headphones due to sound quality + latency, so we (audiophiles) stick to wired at home and we also have dedicated headphone amps since the pissy sound card D/A convertors are incredibly bad. Bluetooth only when I’m doing yard work. Sadly, modern music is tuned to crappy headphones, crappy car systems, crappy speakers … I miss the 80’s audiophile obsession, the equipment had heart, and…

- Apple has a lossless codec for wireless, ALAC that can do up to 24bit/192khz

- aptX can do 44/16 in other devices, Sony has LDAC at 24/96 too

- latency under We have amazing technology available today, at prices and quality unimaginable in the 80s. A $50 in-ear from a chinese hi-fi brand can give you an audio experience you couldn’t buy for thousands of dollars a decade ago. And there’s more and more analog hardware being designed and built as technology costs have fallen. You’re really missing out if you think things were better back then.

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