Wireless Bone Conduction Headphones The Most Advanced Bone Conduction Technology Exceptional audio quality, previously unimaginable in bone conduction headphones. More Bass and Less Vibrations The 30º inclination of the transducers with respect to the face, offers a more dynamic bass and reduces vibrations. Excellent Response to Medium and High Frequencies. The vibration range of the human vov, and higher is purer with a smoother response curve like that offered by Aeropex, comparable or even better than traditional headphones. 50% Reduction in Sound Leaks In Aeropex headphones, the LeakSlayer holes of previous models disappear, thus making them water resistant and more aesthetically attractive. Sound leakage is also reduced by 50% compared to Air. 30% Smaller and 15% Lighter. PremiumPitch 2+ technology makes them smaller and more powerful.
