The OpenRock S utilises 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 emphasises the reduction of fatigue during training, the activation of athletic potential and the increase of training efficiency. Relax mode, on the other hand, was developed to promote relaxation and reduce stress.

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

Each earbud's powerful battery 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, 5 minutes of charging = 1 hour of use.

Bluetooth 5.3 technology enables an effective improvement in transmission speed compared to Bluetooth 5.2, while at the same time increasing energy efficiency and ensuring 100% stable signal transmission.
Four high-quality microphones form an array using beamforming technology to achieve four-point AI call noise cancellation and eliminate ambient noise. Even if the wind around you is strong, the person you are talking to can hear your voice clearly.
In addition, 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.
