The Oraimo OpenArc OPN-675 offers a refreshing open-ear listening experience that keeps your ears free and your awareness intact—ideal for outdoor use or when you want situational hearing. It runs on Bluetooth 5.4, offering up to 8 hours of continuous play, boosted to 36 hours when using the charging case. Features like enhanced bass (via HavyBassTM), a 4-mic environmental noise cancellation system, and quick-charge (10 minutes ≈ 2 hours playback) make it competitive. It includes IPX5 splash/sweat resistance, lightweight ear-hooks (≈10g each), dual-device connection, and customizable lighting via app. Downsides: open-ear design means less passive noise isolation, so windy/very loud environments may reduce perceived bass and clarity. Overall, a strong choice for users who want comfort, awareness, and long battery life.
