A free iPhone app called Zuckoff scans Bluetooth signals to alert users when Ray-Ban Meta glasses, Snap Spectacles, or similar wearable cameras are nearby, estimating their distance. It's part of a growing set of privacy tools, including Antizuck and Nearby Glasses, built in response to concerns that smart glasses can record video without visible warning.
Researcher Matthew Callaghan discovered AliExpress running hidden scripts that generate silent, inaudible sound waves through the WebAudio API to create a unique fingerprint of each visitor's browser. He noticed the tracking only because it interfered with his multipoint Bluetooth headphones, cutting off phone audio whenever the AliExpress tab was open. The scripts muted the sound with a zero gain setting so users would never notice, but the browser still processed and transmitted the audio data back to the site.
Televisions lacking built-in Bluetooth can still gain wireless capability by pairing with streaming devices such as the Apple TV, Roku, or Fire TV Stick, all of which include Bluetooth support for connecting headphones or keyboards. A budget option like the $30 Roku Streaming Stick HD offers this feature while also modernizing the TV's software. For broader compatibility across all inputs, a dedicated Bluetooth transmitter is recommended instead.
Shokz has launched the OpenFit Air 2, an open-ear earbud that weighs about 17 percent less than its predecessor at 7.2g per bud. The earbuds feature an ear-hook design, upgraded bass technology via Bassphere and OpenBass 2.0, Bluetooth 6.1 with multipoint support, and up to 36 hours of combined battery life with the charging case. They launch August 27 for $130, alongside a companion release, the OpenRun Air 2, aimed at runners with a bone-conduction design.
Researchers discovered that AliExpress's homepage runs hidden, inaudible audio-processing code tied to Alibaba's security systems, which measures how a device's hardware handles an audio signal to create a unique fingerprint without cookies. The behavior was uncovered by a developer whose Bluetooth headphones failed to switch between devices while an AliExpress tab stayed open, since the silent audio graph kept the system's audio path active even when muted. The same scripts reportedly also collected canvas, WebGL, and hardware configuration data as part of a broader tracking setup.
