When the ear canal is sealed by an earbud, the speaker vibrations create acoustic pressure. In the confined space of the closed ear canal, these become harmful amplified pneumatic pressures and cause the eardrum to move with an amplitude thousands of times greater than normal. Tiny muscles around the eardrum then tighten to protect the ear by dampening the sound. To overcome this dampening you must turn up the volume. The more the volume increases, the more the eardrum tightens. And so on. And so on.
With ADEL™, it’s quieter – often operating at 1/10th the amplified in-ear power levels of traditional listening devices. And by not prematurely tightening in-ear muscles, which can dramatically compress the volume, loud sounds actually sound louder and require less overall volume levels.
ADEL™ will enhance the way you hear music. This technology adds a second eardrum into all of our in-ear monitors. This second eardrum takes the punishment of the pneumatic pressure caused by sound in the ear canal, and delivers clear, crisp sound that’s unlike anything you’ve ever heard. And it’s not louder noise coming from your earbuds.
The results from theVanderbilt University Medical Center study show that using ADEL™ allows listeners to enjoy Enhanced Loudness Perception (lower volumes sound significantly louder and better over conventional devices). This provides them a louder yet safer, high fidelity listening experience at greatly reduced power levels (1/4 to 1/16th typical levels) with no perceived loss in volume.
The ADEL™ modules were designed for easy removal or installation. The module is housed in an aluminum nest to better protect the module and higher durability for even the most demanding users.
Hear your music the way you want to
With different modules, you can change the level of isolation all while relieving air pressure from the ear canal
S1 Auto Module**
Engineered to automatically tune itself to absorb the pneumatic pressures in your ear canal through a dual membrane design.
B1 Auto Module
A single membrane design, which slightly reduces the bass and brings more spaciousness to the midrange and highs.
G1 Auto Module
A different membrane design, which slightly increases the bass while also reducing the occlusion effect even further to give singers and active wearers fatigue-free listening.
This pair features easily adjustable controllers which can be turned while listening to music, and adjustable valves that help regulate pneumatic pressure, and each has a secondary membrane tensioner, as well as an adjustable "secondary" Eustachian tube.
O1 Auto Module
Designed to isolate sound as much as possible for a 100% in-ear monitor experience. Placed snugly into your IEM or plugs, you will experience maximum isolation and bass response.
