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 ムーンライトグレイ

The Bose Ultra Open Earbuds LE represent a bold departure from traditional earphone design, offering an open-ear form factor that lets you enjoy premium Bose audio while staying connected to the world around you. Available in the elegant Moonlight Gray colorway, these truly wireless Bluetooth earbuds combine style, comfort, and impressive audio technology in a unique package. **Design and Comfort** The standout feature of the Bose Ultra Open Earbuds is their innovative open-ear design. Rather than sitting inside or over your ear canal, these earbuds hook gently over the ear using a flexible, ultra-lightweight joint mechanism. This design choice means you can wear them for extended periods without the fatigue or discomfort often associated with in-ear models. The Moonlight Gray finish adds a sophisticated, jewelry-like aesthetic that makes them as much a fashion statement as an audio device. **Sound Quality and Spatial Audio** Despite their open-ear design, these earbuds deliver remarkably rich sound thanks to Bose's proprietary OpenAudio technology, which ensures high-quality private sound without sealing off your ear canal. The inclusion of Bose Immersive Audio enables spatial audio capabilities, creating a three-dimensional soundscape that makes music, movies, and podcasts feel more lifelike and enveloping. Users can easily toggle between Stereo Mode and Immersion Mode with a simple button press to customize their listening experience. **Staying Connected to Your Surroundings** The core philosophy behind these earbuds is maintaining awareness of your environment while enjoying music. Whether you're commuting, working in an office, exercising outdoors, or spending time at home with family, the open-ear design allows ambient sounds to pass through naturally. This is a significant safety and social advantage over noise-canceling alternatives. **Battery Life and Durability** Battery performance is solid, with up to 7.5 hours of continuous playback in standard mode, or up to 4.5 hours with Immersive Audio enabled. The included charging case provides an additional 19.5 hours of playback, and standby time reaches up to 48 hours. The IPX4 water-resistance rating means these earbuds can handle sweat, light rain, and splashes without issue. An acoustic mesh further protects against moisture and dust ingress. **Connectivity and Smart Features** Bluetooth multipoint connectivity allows seamless switching between your phone, laptop, and other devices without manual re-pairing. The Bose SimpleSync technology opens up additional possibilities by letting you pair the earbuds with compatible Bose soundbars and speakers — perfect for watching TV at your preferred volume without disturbing others. A built-in microphone enables hands-free calls with simple button controls for answering, pausing music, and more. **Pricing** Currently available on Amazon.co.jp at ¥28,800 (20% off the list price of ¥36,000), these earbuds offer Bose's premium open-ear audio experience with spatial audio support and comprehensive connectivity features. **Verdict** The Bose Ultra Open Earbuds LE are an excellent choice for anyone who wants to enjoy high-quality audio without isolating themselves from the world. With spatial audio, comfortable all-day wear, solid battery life, and versatile connectivity, they are well-suited for a wide range of daily scenarios — from commuting and working to exercising and relaxing at home.
