FS1 High Definition Earphones deliver richer sound than you've ever heard before. Featuring a professional-grade audio driver designed by Future Sonics, they utilize technology developed exclusively for live music performances. The technology includes a dynamic transducer that provides smoother and more consistent low frequency response, as well as a more natural overall tone.

In addition, FS1 earphones reduce outside noise and produce a wide spectrum of sound. That means you experience outstanding vocal tones, crisp instrumentals and exceptional bass response. Just the way the artist intended.

The Technology

XtremeMac and Future Sonics, the leading manufacturer of personal monitors for professional musicians, bring you a new generation of professional audio technology. While other earphones use armature-type drivers-the same kind found in hearing aids-the FS1 earphones utilize proprietary drivers and technologies recently developed by Future Sonics.

These drivers produce a natural tone and rich, deep bass-even at the lowest volume levels-that surpass the performance of any other earphones on the market. With a combination of audio quality, performance and style, FS1 earphones are perfect for use with your iPod, laptop, portable DVD player, gaming systems and more.
