> Unbreakable encryption
All wired earphones I have ever used had a line connect which is analog and completely unencrypted. What wired earphones have you had that where encrypted?
- stavros 3y agoThe advantage here is that you need a physical connection to decrypt the content.
- rpigab 3y agoNot if you have a good microphone and the sound is loud
- stavros 3y agoThat's not a failure of the protocol but of the user. It's like saying PGP for email can be broken if you have a telescope to look at the user's screen.

- infinityio 3y agoI wonder if there are attacks based on RF emissions along a cable to get the sound
- MerelyMortal 3y agoYes, there are. You can even get video signals from a video cable.
- rsynnott 3y agoEh... If your adversary can break modern bluetooth encryption, I probably... would not bet on this? I would think that with appropriate radio equipment you can probably pick up audio from many wired headphones.
- autoexec 3y agobluetooth encryption has been broken before. "KNOB" (https://www.usenix.org/system/files/sec19-antonioli.pdf https://www.usenix.org/system/files/sec19-antonioli.pdf) was less than 5 years ago. The kind of equipment that could pick up the audio over a wired headset from across the room could probably pick up something from the speakers of wireless earbuds too.
- kelnos 3y agoI think the GP meant that in theory someone could break into a Bluetooth connection and snoop on your phone calls. But with a wired headset, there's nothing to break into. "Unbreakable encryption" is a bit tongue-in-cheek, there.
- vel0city 3y ago> there's nothing to break into Wired headphones are giving off EMI of the signal they're playing, one could sense that signal with the right equipment and know what you're listening to remotely.
