    Features

    Newly designed drivers for a revolutionary music experience  

    The newly developed large-diameter drivers (9 mm HD TWS drivers with deep bass) deliver deep, powerful bass while ensuring a comfortable fit—an important factor for truly wireless headphones. The airtight fit prevents the bass from escaping to deliver a unique, stress-free music experience.  

     

    Acoustic ducts for rich low-frequency sounds  

    Ducts on the back of the driver control airflow to ensure a detailed acoustic space. The design allows for ideal movement of the driver to deliver rich low-frequency sounds.  

     

    Up to 20 hours*1 without recharging—the best in class!  

    The high-capacity battery provides around 20 hours*1 of continuous playback without charging. Using the headphones with the charging case allows as much as 50 hours*2 of playback, significantly reducing how often recharging is necessary. To help ensure extended usability when not using the charging case, the power can be turned on and off directly on the headphones.  

    *1 As of September 2021 according to in-house figures. With noise-cancelling disabled. Playback for around 15 hours is possible with noise-cancelling enabled. Results may vary depending on usage conditions.  

    *2 Results may vary depending on usage conditions.  

     

    Fast-charging support  

    Charging for just 10 minutes (approx.) provides about 90 minutesof continuous playback. Simply place the headphones in the charging case and plug the case in for a quick charge before heading out.  

    *With noise-cancelling disabled. Results may vary depending on usage conditions.  

     

    Block outside sounds at the press of a button  

    The feed-forward active noise-cancelling function ensures an immersive audio experience even in noisy environments such as those with air conditioners or purifiers or on public transportation.  

    *Noise-cancelling and hear-through functions are disabled by default.  

     

    Enjoy deep bass while being aware of your surroundings with hear-through  

    The built-in microphone captures ambient sounds so users can remain aware of their surroundings during use. The hear-through function is useful for listening to music while walking, doing housework, working remotely, or using public transportation. The comfortable fit ensures a natural experience when using the hear-through function.  

     

    Easy-to-wear, secure fit  

    The newly developed structure ensures a stable fit that prevents the headphones from falling out of the ears. The increased contact surface between the headphone and ear reduces the burden, providing a light, natural fit. The headphones are comfortable even for extended periods, allowing you to enjoy deep bass for longer.  

     

    Hybrid eartip structure combining hard and soft silicone material  

    The headphone’s eartips are soft and pliable for a gentle fit. Meanwhile, the parts of the shaft that transmit sound are stiff to reduce adverse impacts on sound quality and noise-cancelling. The new, hybrid structure utilizes the varying hardness of the two silicone materials to create a comfortable fit with superior sound performance.    

    The tactile umbrella fits naturally in the ear canal for enhanced airtightness, an essential factor for the noise-cancelling function. The high-strength shaft also minimizes sound transmission loss to bring detailed audio directly to the eardrum.  

     

    Intuitive operation that doesn’t hamper enjoyment  

    Designed for reliable, stress-free operation for a more enjoyable experience. The left button adjusts the volume and switches between hear-through and noise-cancelling functions, while the right button lets you easily start/stop playback, skip between songs, or enable quick hear-through.  

     

    Quick hear-through for instant volume adjustment and playback of voices  

    The quick hear-through function is perfect for tuning in or out of your surroundings by allowing you to hear announcements or listen to those around you. This single-action function instantly lowers playback volume and captures ambient sounds while enhancing the vocal bandwidth.  

     

    Minimize audio lag with Low Latency Mode  

    Enjoy a more immersive experience with minimal sound delay while playing games or watching videos on your smartphone or tablet with Low Latency Mode.  

    *Low Latency Mode can also be turned on/off from the Connect app. Bluetooth connections may be affected by obstacles and ambient radio wave conditions.

    When connecting a primary headphone via Bluetooth, the secondary headphone will mirror the audio signal of the primary headphone for independent transmission.  

    Preventing audio signal exchanges from primary and secondary headphones reduces audio interruptions and delays. The reduced communication load on the primary device also helps minimize the amount of power that is used.

    When you hear music with a heavy bass line, you can’t help but feel the urge to dance. Some say its just human instinct. Getting the same experience with in-ear headphones requires a secure fit with excellent sound isolation. Any sound that escapes lessen the intensity of the bass.
