Bose Ultra Open Earbuds 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 ブラック

The Bose Ultra Open Earbuds represent a bold step into the open-ear headphone category, offering a unique listening experience that lets you enjoy rich, immersive audio while staying fully connected to the world around you. Priced at ¥28,800 on Amazon.co.jp, these earbuds cater to listeners who want high-quality sound without the isolation of traditional in-ear designs. At the heart of these earbuds is Bose's proprietary OpenAudio technology, which delivers surprisingly full and detailed sound despite the open-ear form factor. The inclusion of immersive audio (spatial audio) elevates the experience further, creating a three-dimensional soundstage that makes you feel enveloped by your music. You can easily toggle between stereo mode and immersion mode using the onboard button controls, adapting your listening experience to your preference or environment. Comfort is where the Bose Ultra Open Earbuds truly shine. The flexible, ultra-lightweight joint design allows the earbuds to hook effortlessly over your ear, providing a secure yet comfortable fit. Unlike canal-type earphones that can cause ear fatigue or discomfort during prolonged use, these open-ear buds feel almost weightless. The sleek black design adds a touch of style, making them suitable for both workouts and everyday wear. Battery life is respectable at up to 7.5 hours of continuous playback in standard mode. However, it's worth noting that enabling the immersive audio feature reduces this to approximately 4.5 hours. The included charging case provides an additional 19.5 hours of playback, bringing the total to roughly 27 hours — more than enough for most users' weekly needs. Standby time maxes out at 48 hours. On the practical side, IPX4 water resistance means these earbuds can handle sweat, light rain, and splashes with ease, while an acoustic mesh guards against moisture and dust. The built-in microphone supports hands-free calls, and Bluetooth multipoint connectivity allows seamless switching between your smartphone, laptop, and other devices. Additionally, Bose SimpleSync technology enables pairing with compatible Bose soundbars and speakers, letting you watch TV at your preferred volume without disturbing others. The button controls are refreshingly straightforward, covering essentials like play/pause, mode switching, and call answering without the frustration of finicky touch controls. Overall, the Bose Ultra Open Earbuds are an excellent choice for anyone seeking premium open-ear audio with spatial sound capabilities, outstanding comfort, and the reliable build quality Bose is known for. They're particularly well-suited for users who need situational awareness — whether commuting, working in an office, or exercising outdoors — without sacrificing sound quality.
