So, uh, funny thing, pretty sure there's a few Western sites that do this exact thing as well.
I'm not 100% yet, but I've had the exact same functional behavior on LinkedIn as well as Meta sites, despite autoplay being off and no media showing.
AliExpress Silent WebAudio Fingerprinting Uses Bluetooth Hardware
AliExpress uses hidden WebAudio graphs to fingerprint devices, which blocks Bluetooth multipoint headphones from switching audio sources. The tracking relies on obfuscated scripts that maintain an active audio pipeline even when muted.
**If you shop on AliExpress and your Bluetooth headphones stop switching between devices, this is caused by hidden tracking scripts on the site, not broken hardware. Install uBlock Origin and add filter rules to block `collina.js` and `fireyejs.js` on aliexpress.com, then close all open AliExpress tabs and reload the site for the fix to take effect.**
