The much-anticipated successor to the OneOdio OpenRock S, the OpenRock S2, was officially launched in June 2025. This new model showcases a significant shift in design and features compared to its predecessor, aiming to appeal to a broader market while maintaining the essence of open-ear technology.
While the original OpenRock S was celebrated for its rugged design and impressive battery life, the OpenRock S2 embraces a more modern aesthetic. Weighing only 7g per bud and featuring a compact charging case of 58g, these earbuds are designed for convenience, especially for outdoor activities and workouts. The price point of $98.99 / £79.99 / AU$154 positions them as an attractive option for budget-conscious consumers in the competitive open-ear market.
Design and Comfort
The OpenRock S2 adopts a smaller, lighter design compared to its robust predecessor. The new earbuds come with a flexible rubbery sports loop intended for comfort and stability. However, during testing, users may find that the fit can be unreliable, as the buds occasionally shift position, particularly during vigorous activity.
Despite the comfort offered by their lightweight nature, the design has drawbacks. The physical buttons, located on the bottom of the counterweight, can be difficult to press without dislodging the earbuds from the ear. This design choice complicates simple actions like pausing music, which could detract from the overall user experience.
Performance and Features
The OpenRock S2 boasts an IPX5 water resistance rating, making them suitable for outdoor use, but the battery life reflects a notable reduction from the original model. With 8 hours of playback per charge and a total of 32 hours when factoring in the charging case, the S2 falls short of the OpenRock S’s impressive 19 hours per bud and 60 hours total.
The sound profile of the OpenRock S2 emphasizes bass, utilizing technology designed to enhance low-end frequencies. While these earbuds are suitable for workout playlists, their maximum volume may struggle to compete with surrounding noise in busy environments. The introduction of a companion app allows users to access an equalizer with three presets and customizable features, enhancing the listening experience but also complicating the process of adjusting sound settings.
Throughout testing, the connection via Bluetooth 6.0 proved reliable, facilitating a seamless experience for users across various activities, from casual listening to taking calls.
Value Proposition
At their current price, the OneOdio OpenRock S2 presents a compelling option in the open-ear segment. While they may not deliver the same level of ruggedness or battery longevity as their predecessors, their affordability makes them attractive to consumers seeking a balance between quality and cost.
The S2 competes well against other models in the market, offering a solid alternative for those who prioritize lightweight design and decent sound quality without breaking the bank. However, for users who valued the unique features of the original OpenRock S, the changes in design and performance may lead to disappointment.
In summary, the OneOdio OpenRock S2 offers a fresh take on the open-ear concept, catering to a wider audience while sacrificing some of the distinct qualities that defined its predecessor.
