Technology apex core 64 Audio's patented technology is seamlessly integrated into the body of the earphone. The pressure relieving channel provides controlled venting via acoustic filters. Aspire 1 users get the benefits of 64 Audio's flagship technology with -20dB of isolation combined with ear saving venting. Helmholtz Resonator 3D Printed micro-cavities operate by forcing air in and out, causing the air inside to resonate at a specific frequency. By precisely determining the dimensions of the cavity and its neck, we can target a very narrow resonant frequency to amplify or diminish.
