Lightweight inner-ear type to reduce burden on the ears】 Unlike conventional canal-type earphones, these adopt a semi-in-ear shape that is gentle on the ears. With a lightweight design, you can enjoy comfortable wear that reduces pressure and ear fatigue even during long hours of music listening or online meetings. You can use them with peace of mind even if you have sensitive ears. 【Powerful bass and rich sound quality that can be customized to your liking】 The default sound emphasizes the bass, powerfully reproducing rhythmic music. Using the dedicated app "Edifier ConneX," you can easily switch between multiple sound modes, such as "Vocal" mode (for vocals) and "Movie" mode (ideal for watching movies). Furthermore, by making fine adjustments with custom EQ, you can freely create your ideal sound. 【Maintain concentration with comfortable noise cancellation】 Active noise cancellation (ANC) effectively reduces persistent low-frequency noise such as air conditioners and PC fans. There is less pressure on the ears, making them comfortable for long hours of use. Perfect for concentrating in the office, working from home, or studying. Equipped with an ambient sound mode, you can clearly hear surrounding voices and announcements. 【Connect with the world with AI real-time interpretation】 The built-in AI interpretation function translates up to 21 languages in real-time. It is useful in various situations, such as watching foreign dramas and videos, online meetings, and travel conversations. It can be used offline, so you can use it without Wi-Fi or data communication. It enables smooth communication by overcoming language barriers.
