Bose Ultra Open Earbuds LE 空間オーディオ イヤホン オープンイヤー 完全 ワイヤレス Bluetooth接続 マイク付 最大7.5時間再生 防滴 ディーププラム

The Bose Ultra Open Earbuds LE in Deep Plum represent a bold reimagining of how we listen to music on the go. Unlike traditional in-ear or over-ear designs, these open-ear wireless earbuds sit on your ear without blocking the ear canal, allowing you to stay connected to your surroundings while enjoying high-quality audio. **Design and Comfort** The design is immediately striking and unlike anything you'd expect from a conventional earbud. The earbuds feature a flexible, ultra-lightweight joint mechanism that clips gently onto the ear. The result is a secure yet remarkably comfortable fit that can be worn for extended periods without fatigue. The Deep Plum colorway adds a touch of sophistication, making these earbuds as much a fashion statement as an audio device. **Sound Quality and Spatial Audio** Despite the open-ear form factor, Bose's proprietary OpenAudio technology delivers surprisingly rich and full sound that stays private to the listener. The standout feature here is Bose Immersive Audio, which enables spatial audio for a three-dimensional listening experience. Users can switch between Stereo and Immersion modes via simple button controls, tailoring the soundstage to their preference. In Immersion mode, the audio feels enveloping and remarkably lifelike. **Battery Life** Battery performance is solid, with up to 7.5 hours of continuous playback in standard mode and up to 4.5 hours with Immersive Audio enabled. The included charging case provides an additional 19.5 hours of playback, while standby time extends up to 48 hours. For daily commutes and workouts, this should be more than sufficient. **Durability and Connectivity** The earbuds carry an IPX4 rating for splash resistance, meaning they can handle sweat and light rain without issue. An acoustic mesh further protects against moisture and dust. On the connectivity front, Bluetooth multipoint support allows seamless switching between devices such as your phone and laptop. A built-in microphone enables hands-free calls, and Bose SimpleSync technology lets you pair the earbuds with compatible Bose soundbars and speakers for a personalized TV-watching experience at your preferred volume. **Verdict** At ¥28,800, the Bose Ultra Open Earbuds LE are a premium investment, but they deliver on their promise of high-quality, open-ear audio with the added dimension of spatial sound. They are ideal for anyone who wants to enjoy music without completely shutting out the world — whether during a morning jog, at the office, or while running errands. The combination of Bose sound quality, innovative design, and practical features makes these earbuds a compelling choice in the open-ear category.
