Apple has updated its Beats Studio Buds wireless earbuds to patch a high-severity vulnerability that could be exploited by nearby hackers to eavesdrop on users.

The vulnerability, CVE-2025-20701 , allowed improper authentication in the firmware running on the Bluetooth-related chips, enabling people within signal range to impersonate devices that had previously been paired with the earbuds. The researchers demonstrated this in a series of end-to-end attacks that allowed them to eavesdrop on conversations or sounds within earshot of the phone microphone.

“Impact: An attacker within Bluetooth range may be able to listen through the microphone of a device which is not yet paired and actively seeking pair requests,” Apple said in a Tuesday security advisory . The fix is contained in Beats Firmware Update 1B211, which is delivered automatically while headphones are paired with and within Bluetooth range of a user’s iPhone, iPad, or Mac. Users can check their firmware version by going to Settings on their device, navigating to Bluetooth, and tapping the info button next to the headphones.
