The OpenRock S uses an open ear design with directional sound transmission that protects your hearing without compromising sound quality. The ear hooks are made of skin-friendly silicone and can be adjusted to different ear sizes for a secure fit.

OpenRock S offers different sound modes specially designed for sports activities. The Rock mode emphasizes reducing fatigue during training, activating athletic potential, and increasing training efficiency. The Relax mode promotes relaxation and reduces stress.

OpenRock S earphones utilize TubeBass technology to improve low frequencies and concentrate the energy emitted by the speaker on the ear canal. They feature 16.2mm dynamic speakers and high-quality diaphragms that provide unprecedented bass performance for long listening sessions.

The powerful battery of each individual earbud supports up to 19 hours of continuous playback at 70% volume. With interim charging in the included charging box, the headphones offer a total of 60 hours of playback time on a single charge and support fast charging, with 5 minutes of charging providing 1 hour of use.

The latest Bluetooth 5.3 technology enables an effective improvement in transmission speed compared to Bluetooth 5.2, while increasing energy efficiency and ensuring stable signal transmission.

Four high-quality microphones form an array using beamforming technology to achieve AI call noise suppression and eliminate ambient noise. Even in strong winds, the person you are talking to can hear your voice clearly.

Additionally, the OpenRock S is IPX5 waterproof, sweat and rainproof, and the open-ear technology ensures that you can also hear ambient noise, which is particularly important for safety during outdoor sports.
