OneOdio OpenRock S2 wireless headphones (black)

OpenRock S2 are wireless headphones that let you enjoy your favorite tunes without cutting you off from the world around you. Thanks to the special open-ear design, you can listen to music while running, cycling or hiking in the mountains and at the same time stay safe - you can still hear traffic or other people's voices. This is a great choice for active users! The headphones boast excellent sound quality, long battery life (up to 8 hours) and Bluetooth 6.0 connectivity, and are also compatible with the OpenRock app, which allows you to conveniently manage their operation.

Powerful sound, natural sound

The OpenRock S2 headphones are Hi-Res Audio Wireless (High Resolution Audio Wireless) certified and support LDAC (Low Latency Audio Codec), which means they transmit high-resolution music in every detail. BassDirect™ technology further enhances low frequencies, delivering deep, dynamic sound. This combination makes every song sound incredibly natural and spacious.

Crystal-clear conversations with noise cancellation

The headphones feature four microphones and AI Noise Cancellation technology. This technology effectively filters out background noise and wind noise during calls, ensuring your voice remains clear and crisp even in challenging conditions. Whether you're talking during a workout or on a busy street, you can always count on excellent call quality.

Long operating time and fast charging

OpenRock S2 gives you up to 8 hours of continuous music playback, and the charging case extends this time to approximately 32 hours. Plus, with the quick charge feature, it only takes 5 minutes to get power for another hour of playback.

Stable fit and comfort

With an ergonomic design and a special over-ear headband, the OpenRock S2 headphones stay stable even during intense running or cycling. Plus, each earbud weighs just 7g – you won’t even feel like you’re wearing them. There’s also skin-friendly silicone and an IPX5 (Ingress Protection X5, sweat and splash resistant) rating, which means the S2 will perform well even during extremely intense workouts!

OpenRock app - complete personalization

Thanks to the dedicated app, you have full control over your headphones. For example, you can choose from the available modes (Rock, Relax or Boom) that match the sound to your favorite music, or use the Spatial Sound function that gives the impression of surround sound. The app also offers a volume limiter, wearing time reminders and customizable buttons. In addition, the Find My Buds option will help you quickly find your headphones if you lose them.

Stable connection with multiple devices

The OpenRock S2 uses Bluetooth 6.0 technology, which ensures a stable and fast connection. In addition, you can connect the headphones to, for example, a smartphone and a laptop at the same time and then switch seamlessly between them - without re-pairing.

Remote camera control

The OpenRock S2 isn't just for music and calls. With the convenient camera remote function, you can take photos and videos with your smartphone with a single button on the headset. This is great for travelers and content creators who want to capture their adventures in an easy and convenient way.
