In a startling revelation that could leave many audiophiles worst unsettled, experts have uncovered severe vulnerabilities in a range of popular audio devices. Hackers have ingeniously found a way to exploit Bluetooth technology used in headphones, earbuds, microphones, and speakers, raising alarms about potential eavesdropping and data theft.

What You Need to Know About the Bluetooth Threat

This dire situation underscores the alarming reality of cybersecurity risks lurking within devices we casually use every day—those that help us unwind with music and podcasts. According to Dennis Heinze, a security analyst at ERNW, any device within Bluetooth range can be compromised, setting off a wave of concern among users.

Recent research has spotlighted critical security flaws among various brands utilizing Airoha Systems on a Chip. Airoha is a major player in the Bluetooth audio sector, specifically for True Wireless Stereo (TWS) earbuds. Although ERNW has opted to withhold detailed proof of concept, the mere acknowledgment of these vulnerabilities is enough to send shivers down the spine of tech-savvy consumers.

Danger Lurking in Your Favorite Brands

Heinze revealed that these vulnerabilities pave the way for hackers to seize unauthorized control over Bluetooth headphones without the need for authentication or pairing. This means if you're within range of an attacker, your devices could be at risk; they could access the device’s RAM and flash memory and even hijack its connection to your smartphone.

Among the high-risk vulnerabilities, the two notable ones assigned critical ratings under the Common Vulnerability Scoring System are CVE-2025-20700 and CVE-2025-20701 (severity score 8.8/10) and CVE-2025-20702, presenting a staggering score of 9.6/10.

Real-World Implications of Audio Spy Attacks

While the fears stemming from these revelations are certainly justified, Heinze suggests the practical impact can vary. One demonstration involved reading audio content via device RAM, while more alarmingly, attackers can exploit these vulnerabilities to listen in on recordings made by the device's microphone—it necessitates the headphones being powered on but not in active use.

The ramifications extend beyond eavesdropping. If a hacker impersonates your headphones, they can potentially issue commands to your smartphone, gaining access to call histories and even enabling covert conversations.

Who Should Be Most Concerned?

It's important to note that the most likely targets of these attacks are not average consumers but rather individuals in sensitive fields—journalists, diplomats, and political figures—who are generally advised against using Bluetooth audio devices. Until firmware updates are rolled out, at-risk users are urged to refrain from using their headphones.

Boris Cipot, a senior security engineer, emphasized the constant challenges in ensuring complete trust among technologies, especially as new vulnerabilities emerge. He stressed that timely software updates are paramount for user safety.

Vulnerable Devices — Are Yours on the List?

Fortunately, Airoha has acknowledged these issues and provided fixes in their software development kit, pushing manufacturers to issue firmware updates. A number of popular models have been confirmed vulnerable, including:

• Beyerdynamic Amiron 300 • Bose QuietComfort Earbuds • Jabra Elite 8 Active • Several models from Sony (including WF-1000XM3 and WH-1000XM5) • Marshall’s audio line-up • Many others operating on Airoha chip technology.

Jabra has noted that they are actively rolling out firmware updates to address the vulnerabilities, ensuring that users of the Elite 8 and 10 models are protected.

Stay Informed, Stay Safe!

As these issues linger, staying informed and proactive is key. Users of Bluetooth audio devices should monitor for updates and practice caution in their usage habits—like removing pairings with mobile devices until fixes are deployed. Protecting your privacy might just depend on it.
