Your Headphones Are Being Hijacked by AliExpress (And It’s Not an Accident)

You know that sinking feeling when your car audio suddenly goes haywire, jumping between podcasts and silence, your phone screen dark, no app in sight? Or when your multipoint Bluetooth headphones refuse to switch from your laptop to your phone, even though you’re clearly taking a call? You’ve probably blamed your phone, your car, your headphones. But here’s the truth: it’s likely AliExpress silently fighting your operating system for control of your Bluetooth hardware.

Your headphones are not just a privacy issue anymore. They are a battlefield.

This isn’t a conspiracy theory. It’s a reproducible bug. Users have documented that opening the AliExpress website triggers a silent WebAudio stream that keeps the PC-to-headphone link active, blocking your phone from connecting. The iOS app does something similar: leave it in the background, and your car audio freaks out as if you’re issuing a voice command. Kill the app, and the problem vanishes. Every time.

What’s happening here is a new, insidious escalation of surveillance capitalism. AliExpress is using WebAudio fingerprinting—a technique that generates a unique profile of your device by playing an inaudible sound and measuring how your hardware responds. To do this, it needs to keep the audio channel open. Even when you’re not listening. Even when the tab is backgrounded. The result? Your Bluetooth multipoint connection is hijacked. Your OS loses the battle for the audio stack. And you lose control of your own physical devices.

This is not a bug. This is a feature of the tracking economy. The tracker doesn’t care about your listening experience—it only cares about your fingerprint. But the collateral damage is real: your headphones stop working, your car audio throws a fit, and you’re left wondering why your $300 Bluetooth earbuds suddenly feel like cheap toys.

Let’s be clear about what this means. We’ve long known that ad-tech companies track our browsing habits, our location, our searches. But now, they are actively interfering with the hardware you own. They’re using your browser’s audio capability as a weapon against your operating system’s resource management. It’s no longer just about data; it’s about control of the physical world.

Surveillance capitalism has finally learned to punch you in the ears.

One user on Hacker News described it perfectly: ‘I noticed in the last few weeks that if I’d recently opened the AliExpress iOS app, my car audio would freak out thinking I was giving it an audio command. Killing the AliExpress app immediately fixed the problem.’ Another user echoed: ‘They have been doing this for months. No sound playing but the audio would change like the microphone was being activated.’

This is not a bug. It’s a deliberate strategy. And it’s a strategy that should terrify you—not because of some abstract privacy concern, but because it’s breaking your stuff. Right now. Today.

So what can you do? You could block the site entirely. You could use a browser that kills background audio automatically. You could demand that Apple and Google finally gate audio playback behind a permission, just like they do with the camera and microphone. But the real question is: how many other websites are doing this, and how many other hardware glitches are we blaming on ourselves?

Here’s the twist: the same technology that makes your headphones glitch is also the technology that will eventually force a reckoning. When enough people realize that their $500 smartphone is being hijacked by a shopping app, they’ll stop blaming their devices and start blaming the system. The war for your privacy has moved from your screen to your ears. And you’re losing—not because you’re careless, but because the battlefield was never visible.
