Casque OneOdio OpenRock S2 Wireless

OneOdio OpenRock S2 Wireless Headphones (black) are open-ear wireless headphones designed for active users who want to listen to music while remaining aware of their surroundings. The OpenRock S2 combine Hi-Res Audio Wireless certification, LDAC support and BassDirect™ technology to deliver detailed, natural sound. They feature Bluetooth 6.0 connectivity, up to 8 hours of playback on a single charge (about 32 hours with the charging case), and compatibility with the OpenRock app for sound and feature customization.

Advantages

The open-ear design allows you to hear ambient sounds such as traffic or voices while listening to music, increasing safety during outdoor activities. Four microphones with AI noise cancellation ensure clear voice transmission during calls by reducing background and wind noise. Lightweight ergonomic earphones with a over-ear headband and IPX5 rating provide a stable, comfortable fit even during intense workouts. Fast charging gives approximately 1 hour of playback after a 5-minute charge.

How to use

Put the OpenRock S2 on with the headband over the ear and position the ergonomic ear pieces to sit comfortably without blocking the ear canal. Pair the headphones with your device via Bluetooth 6.0 and, if desired, install the OpenRock app to select sound modes (Rock, Relax, Boom), enable Spatial Sound or customize button functions. Use the fast-charge feature when battery is low: a 5-minute charge provides about one hour of playback. For calls, speak normally; the four microphones and AI noise cancellation help keep voice clarity in noisy environments.

Recommendations

For outdoor running or cycling, keep volume at a level that preserves awareness of traffic and surroundings. Use the OpenRock app to personalize sound and activate wear time reminders. Clean the silicone parts gently and avoid submerging the headphones — IPX5 protects against sweat and splashes but not full immersion.
