In recent years, a large number of bone conduction headphones have emerged on the market, but there aren’t many excellent models that are lightweight, stable, and comfortable to wear. Models priced below 500 often have numerous drawbacks, and the user experience varies greatly. If one wants to enjoy excellent sound quality, they would have to choose a bone conduction headphone priced at around a thousand yuan. This is quite a luxury for most netizens.
The good news is that as time goes on and with the intense competition among brands, some brands have started to introduce models with outstanding configurations at affordable prices. For instance, the NANK Runner4, featuring a lightweight design with a net weight of just 26 grams, has also undergone ergonomic design upgrades, ensuring that prolonged use will not cause pressure or discomfort to the ears or head.

26g is very light and comfortable. Your ears truly feel unburdened. A 27% reduction in weight.
With lightweight design and highly integrated precision structure, it achieves a more compact size and a comprehensive weight reduction of 27%, making the headset weigh approximately 26g. The new 0.7mm flexible titanium wire, combined with liquid skin-friendly silicone wrapping, fits comfortably on different head shapes, providing a more stable fit and longer wearing comfort.
With an ergonomic memory elastic design based on research conducted on hundreds of users, it is specially developed for the ears of Chinese people, creating a more fitting earphone contour. Adopting a streamlined engineering design with 15 different tension zones in both vertical and horizontal directions, it evenly distributes the force to ensure both comfortable wearing and stable fixation of the earphones.
The third-generation Xiang technology represents a groundbreaking innovation in bone conduction acoustic technology and signifies the technical standard of the bone conduction industry. Building upon the foundation of the second-generation Xiang technology, it enhances the vibration efficiency of the transducer to over 60% through more refined structural stacking and improved sound field reproduction, thereby elevating the sound quality across all frequency bands by more than 80%. This provides users with a clearer and more precise musical experience. Furthermore, it introduces more senior acoustic engineers and Binaural Audio Rendering algorithms, elevating the sound field reproduction to over 90%, creating a delicate and immersive auditory experience.
The newly upgraded Binaural Audio Rendering dynamic bass acoustic algorithm optimizes the frequency response of audio signals through real-time frequency analysis and adjustment, achieving a balanced and natural sound output across different frequency bands. It intelligently calculates and effectively optimizes low-frequency sound for consistently excellent audio quality.
Crafted by the NANK Golden Ears Acoustic Laboratory, the newly upgraded version integrates three key technologies: dynamic bass enhancement, ear canal compensation, and personalized listening experience tuning. It delivers Golden Ears sound quality, preserving more sound details, ensuring that every audio track is expressed clearly and every note is full and transparent. This makes the musical presentation even richer and more dynamic in detail.
Upgraded OT Closed Leakage Reduction Technology 3.0 effectively addresses shell vibration through OT closing technology and outputs reverse sound waves to cancel out leaked sounds, reducing leakage by 90%.
The headset has a protection rating of up to IP68, which is an extremely high level of protection under the IP standard. It can completely prevent dust ingress and remain fully functional even after being submerged in water at a depth of over 2 meters for 1 hour.
The underwater-exclusive sound effect has been optimized for the sound propagation characteristics of underwater environments, making each note more full and rich in texture.
Newly Upgraded Bluetooth 5.4
Maximized Performance, Enhanced Experience
The new Bluetooth 5.4 wireless SOC is faster, more stable, reduces audio quality loss and latency, and supports advanced audio decoding, comprehensively enhancing sound quality.
