XSound 4 Helmet Speakers

Nearly a decade ago, we introduced the XSound 3, the first helmet speaker with Hi Def audio. Since then, we’ve made progressive adjustments to enhance the music listening experience. The XSound 4 introduces our patent-pending acoustic flex (AF) ultra soft tech covers, taking comfort and sound quality to a whole new level. These covers are meticulously designed to position and channel audio precisely to your ears within the confined space of a helmet. They wrap audio frequencies and direct them accurately to your ears, minimizing audio loss.

For proper installation, the XSound 4 helmet speakers need to be touching your ears during use inside your helmet. You may use the included foam spacing pads to achieve this.

We also recommend that the helmet speakers are mounted in a more forward and lower position in the ear pockets to accommodate your ears more effectively.

Proper speaker placement is crucial. Please install the included foam pads to position the speakers to be right up to the ears. Any space left between the ear and speaker will result in a lower volume and usually leads to the volume being turned up to excessive levels. THIS MAY CAUSE PERMANENT DAMAGE TO THE SPEAKERS. IASUS does not recommend listening to music at excessive levels which may lead to hearing damage.
