Earaku (イアラク) オープン イヤホン bluetooth ワイヤレス 【業界にない新発想】 スポーツ ランキング 在宅勤務 耳を塞がない 防水防汗 物理ボタン 音漏れ防止 マルチポイント Type-C充電 外の音が聞こえる 自動ペアリング グレー

The Earaku Open Ear Bluetooth Wireless Earphones offer a refreshing alternative to traditional in-ear designs, built around the concept of keeping your ears open to the world while still enjoying quality audio. Designed with sports enthusiasts and remote workers in mind, these earphones deliver a compelling combination of comfort, functionality, and value. The most distinctive feature is the behind-the-head ear-hook design. Unlike conventional earbuds that sit inside your ear canal, the Earaku rests gently around your ears, virtually eliminating the pressure and discomfort that comes with prolonged use. The remarkably lightweight body makes it easy to forget you're even wearing them during extended work-from-home sessions or lengthy video conferences. When not in use, the earphones fold down compactly, slipping neatly into a bag or pocket for easy portability. Sound quality is surprisingly solid for an open-ear design. Soft ear cushions wrap around the ears to provide a comfortable fit while delivering clear highs and deep, powerful bass. Despite the open design, the earphones feature sound leakage prevention technology, making them more socially acceptable in shared spaces like offices or public transportation. The open-ear architecture also means you can naturally hear ambient sounds — a critical safety feature for joggers, cyclists, and commuters. Connectivity is handled by a Bluetooth 5.4 chip, which brings improved power efficiency and stable wireless connections within approximately 10 meters (without obstacles). The earphones support multipoint connectivity, allowing simultaneous pairing with two devices — incredibly useful for switching between a smartphone and laptop during remote work. Auto-pairing ensures hassle-free reconnection after the initial setup. Compatibility spans across iPhone, Android, and tablets. Battery life is a standout feature, with up to 23 hours of continuous playback on a single charge. This is more than enough to get through a full workday and an evening workout without reaching for the charger. When you do need to recharge, the USB Type-C port makes it quick and convenient, and you can likely use the same cable as your smartphone. Durability is addressed with an IPX6 waterproof and sweat-proof rating, providing solid protection against rain, sweat, and dust during intense workouts or outdoor activities. Physical buttons replace touch controls, reducing the accidental inputs that plague many wireless earphones — a practical choice for users who operate controls while exercising. Currently available on Amazon Japan at ¥3,980 (30% off the regular price of ¥5,689), the Earaku Open Ear Earphones represent strong value for anyone looking to explore the open-ear category. Whether you need a reliable companion for daily runs, work-from-home meetings, or everyday commuting, this product covers a wide range of use cases with thoughtful design choices.
