Key Advantages

1. Audiophile Sound Quality

The composite diaphragm structure combines the rigidity of PET and the excellent damping of TPU, which brings smooth high frequency, flat frequency response, and eliminates unwanted resonance noise from plastic or metal frames. It features low distortion across the entire frequency range, delivers tight and deep bass with clear transient response, letting you enjoy premium music playback and clear navigation instructions even during riding.

2. Unmatched Durability for Outdoor Use

Engineered to withstand tough outdoor conditions: the black TPU material delivers excellent UV resistance and hydrolysis resistance, maintaining stable performance in long-term sun exposure and wet rainy rides. With over 100,000 cycles of fatigue life and less than 5% performance decay in high temperature and high humidity, it outlasts ordinary stock speakers for long-term use.

3. Easy Modification & Wide Compatibility

With its mature 25.2Ω impedance close to the universal 32Ω aftermarket standard, the driver is easy to drive. The high 123.56dB sensitivity ensures sufficient output volume even with Bluetooth host devices, so you can hear clearly in windy riding conditions. It fits most standard helmet modification workflows and existing production lines, making DIY upgrade simple and accessible.
