Xiaomi Bone Conduction Headphones 2

Manufacturer: Xiaomi

The Xiaomi Bone Conduction Headphones 2 are a neckband-style pair of wireless earbuds built around open-ear bone conduction technology, making them a practical option for those who want to stay aware of their surroundings while listening. They weigh 33.5 g and include wingtips for a more secure fit during activity, with stereo speaker output delivered through the bone conduction transducers.

On the technical side, the headphones carry an IP68 rating with a 5-meter waterproof depth, suitable for swimming and water-based activities. Battery capacity sits at 165 mAh with a rated playback time of 12 hours, fast charging support, and USB Type-C connectivity. The unit integrates four microphones with noise-canceling capability for calls, supports AAC audio codec over Bluetooth with a maximum range of 10 meters, and includes 32 GB of internal storage alongside voice prompts and an on-device control panel.

Pros
  • IP68 rating with a 5-meter waterproof depth makes these headphones suitable for swimming and water sports
  • Open-ear bone conduction design allows users to remain aware of their surroundings while listening
  • 12 hours of battery life provides extended use between charges, supported by fast charging
  • 32 GB of internal storage enables offline listening without relying on a connected device
  • Four-microphone array with noise cancellation supports clearer call quality in noisy environments
  • Wingtips and neckband form factor help keep the headphones secure during physical activity
Cons
  • No active noise cancellation or passive noise isolation, so audio can be disrupted in loud environments
  • AAC is the only supported high-quality audio codec, with no LDAC, aptX, or any of its variants available
  • Wireless charging is not supported, requiring a wired connection for every recharge
  • No find-device feature, which can make locating misplaced headphones difficult
  • Bluetooth range is limited to 10 meters, restricting movement away from the paired source device
Who is this for?

These headphones are well-suited to active users who need to stay aware of their surroundings during exercise or outdoor activities, thanks to the open-ear bone conduction design and secure neckband fit with wingtips. The IP68 rating with a 5-meter waterproof depth makes them a practical choice for swimmers and those who train in wet or harsh conditions. Users who want extended sessions without frequent recharging will also benefit from the 12-hour battery life combined with fast charging support, and those who prefer offline listening will find the 32 GB of internal storage particularly useful.

Who is this NOT for?

Users who prioritize audio immersion or work in noisy environments will find these headphones limiting, as they offer no active noise cancellation or passive noise isolation by design. Audiophiles or those who require high-resolution wireless audio will be constrained by the lack of advanced codecs such as LDAC or aptX, with AAC being the only option available. The 10-meter Bluetooth range also makes these headphones a poor fit for users who need to move freely at greater distances from their source device, such as in large spaces or studio setups.

Final Verdict

The Xiaomi Bone Conduction Headphones 2 occupy a well-defined space for users whose priorities center on physical activity and situational awareness rather than audio isolation. Their IP68-rated waterproofing with a 5-meter depth rating, combined with the open-ear bone conduction design and secure neckband fit, make them a genuinely capable option for swimmers and outdoor athletes. The 32 GB of internal storage and 12-hour battery life with fast charging add practical day-to-day value that goes beyond what many sport-oriented headphones offer. Where they fall short — namely in codec support and noise management — reflects the inherent trade-offs of the bone conduction format rather than oversights in execution. For users who need a durable, water-ready headphone that keeps them connected to their environment, the Xiaomi Bone Conduction Headphones 2 deliver a focused and coherent feature set.
