The ADEL will come in two versions, where a “balloon” will completely surround a driver unit, where the membrane will replace the entire structure of a traditional earphone, including the plastic, metal, or wooden housing and eartip; in addition to a retrofit to existing eartips, where small vent holes are drilled into the collar that fits around an in-ear phone’s driver unit, followed by covering it with small sections of membrane.
A diaphonic pump can then be mounted in line or on the tiny drivers (due to its extremely small design) that sees action in earphones, and while inside the balloon units, it will turn what used to be wasted energy by moving driver into inflation pressure so that the membranes remain seated tightly in the ear canals. Now that’s a custom fit!
