The Hybrid style earphone is patented by Aurisonics in NashvilleTN. This is the combination of a dynamic driver (Future Sonics made them famous) and the armature driver (that Shure and Westone use). The dynamic is known for it's massive low end. Armatures are better suited for highs. Combining the two creates the best of both worlds. Ass kickin' lows and a balanced high end. The earphones on this page are the best on the market today (my opinion).
On the left, check out the size of the dynamic drivers in the Aurisonics Hybrids. The Armature in the middle is used for the high end. Compare these giant speakers in your ears to two of those little armatures (commonly called - dual drivers).
The HDBA tweeter was designed from the ground up for specific application in our patented Hybrid Dynamic driver configuration. Our HDBA tweeter incorporates a new reed design along with other tuning enhancements to make it complement our dynamic drivers perfectly. The HDBA driver is exclusive to Aurisonics Inc.
