OJW Open-Ear Headphones feature an open-ear design that keeps your ear canal unobstructed, allowing you to enjoy music while remaining aware of traffic, conversations, and other surrounding sounds. The ultra-lightweight 0.3 oz design, flexible titanium memory wire, and ergonomic ear hooks provide a secure and comfortable fit for a wide range of ear shapes, reducing ear pressure and making them suitable for extended wear throughout the day. The stable ear-hook structure stays securely in place during running, cycling, walking, hiking, gym workouts, commuting, work, and other daily activities without easily slipping. Unlike traditional wireless earbuds, OJW features a patented replaceable battery system with an included backup battery, allowing you to swap batteries in seconds instead of waiting for recharging. Simply carry the spare batteries for short trips without bringing the charging case, providing a convenient power solution for travel, outdoor activities, and long workdays. Multiple battery swaps provide up to 96 hours of total playtime. Equipped with 13.2 mm dynamic drivers, these open ear earbuds deliver clear vocals, balanced mids and highs, and natural sound for music, podcasts, and phone calls. As with all open-ear headphones, the open design prioritizes comfort and environmental awareness over the stronger bass typically produced by sealed in-ear earbuds. Dual ENC microphones help reduce background noise for clearer voice calls, while Bluetooth 5.4 provides fast, stable wireless connectivity with iPhone, Android devices, tablets, laptops, smart watches, and other Bluetooth-enabled devices. The IPX7 waterproof rating helps protect the headphones against sweat, rain, and everyday workouts, while touch controls allow convenient management of music playback, calls, volume, and voice assistants without reaching for your phone.
