The ATH-AL5NC proposes a brand-new listening style that could be called a "third option," equipping open-back headphones with noise-cancelling technology.
Freeing you from the sense of pressure and stuffiness common in typical closed-back active noise-cancelling headphones, while reducing the ear fatigue often associated with true wireless earbuds. It only reduces unnecessary noise such as ambient living sounds, air conditioning hums, or commuting clamor, allowing you to naturally perceive the sounds you need to hear, realizing "tranquility with a sense of openness".
In addition to the rich, airy tone brought by the newly designed large-diameter φ53mm driver unit, it also achieves a lightweight design and a light, breathable, and stuffiness-free wearing experience. Furthermore, active noise cancellation can be used in both wireless and wired connections, allowing for extensive use in various situations. To ensure you remain comfortable even during prolonged use, we have achieved a perfect balance between comfort, sound quality, and tranquility.
Whether relaxing at home, focusing on work, commuting, traveling, or immersing in entertainment experiences. It accompanies you comfortably all day, allowing you to enjoy high-quality sound without pressure in any scenario — this is the brand-new "open-back active noise cancellation" listening experience pioneered by the ATH-AL5NC.
Preserving the open-back headphones' characteristic of naturally hearing outside sounds, the active noise cancellation technology accurately suppresses unnecessary mid-to-low frequency noises like air conditioning hums or driving noise. Whether "listening while doing" or "moments needing focus", it fits perfectly, providing you with a brand-new experience of tranquility.
Achieving "noise cancellation with a sense of openness" through low lateral pressure design
Reduces the "tight head pressure" characteristic of closed-back active noise-cancelling headphones. Even with prolonged wear, it reduces noise with less fatigue, allowing you to comfortably continue meetings, work, and audio-visual viewing.
Active noise cancellation intensity can be switched between "Home ⇔ Airplane"
Provides natural suppression in less noisy environments, and more powerful noise cancellation in noisy environments. You can choose the most suitable level of tranquility for different scenarios.
Experience open-back active noise cancellation through sound
You can simulate and experience the noise cancellation effect while comparing the difference between turning it off and on.
A balanced design that prevents fatigue in any scenario, whether it's working from home, long meetings, watching movies, or playing games.
Sound diffuses lightly in the space, naturally depicting the texture of vocals and instruments. Perfectly showcases the unique charm of open-back headphones—full of airiness and excellent sound image localization.
* LDAC / AAC codecs can be switched at any time via the dedicated "Connect" app.
* Low Latency Mode will be disabled when the LDAC codec is selected.
Equipped with a mode that suppresses high-frequency sounds that easily leak out. For example, when you step into a store during a walk and need to be considerate of your surroundings, you can temporarily reduce sound leakage. Designed for easy use even in quiet environments such as airplane cabins, trains, or cafes.* This function cannot completely prevent sound leakage. Please pay attention to the volume level.* Since this mode suppresses frequency bands prone to leaking, the listening experience will differ from the normal state.
Enjoy the fun of sound variations through the original (flat) and 4 preset equalizers. In addition, you can customize the equalizer yourself to create your preferred tone. You can choose the most suitable sound quality setting based on your preference and usage habits, selecting from an intuitively adjustable Graphic Equalizer or a Parametric Equalizer for more advanced settings
According to your preference, you can assign operation commands such as switching ambient sound control or turning on/off Low Latency Mode to the NC (noise cancellation) button on the headphones. Through customized settings suited for each user, a more seamless and smooth experience is realized.
In addition to English voice guidance, a Japanese version is also available to make the headphones easier to operate. Please select your preferred language to enjoy a more comfortable and smooth user experience.
