    5.0/5,
    Pros - Good isolation( considering it adds an open vent in the faceplate)
    More natural sound
    Airier soundstage
    enhanced loudness perception
    doesn’t influence the IEM weight and thickness too much
    Cons - Price is not cheap
    Minimal issues with wind noise

    This will not be a review about InEarz Euphoria model, but just a comparison between the Euphoria with ADEL technology and standard one.

    For the first part of this article, I will share some info about this technology, in the second part you can find my personal experience with ADEL and a sound comparison between EUPHORIA ADEL and standard model.


    WHAT ASIUS TECNOLOGIES CLAIMS:

    ADEL™ is the world's first and only patented technology that safely delivers a louder, more spacious and richer sound in professional In-Ear Monitors & Earbuds- all while avoiding the risk of hearing damage caused by earbuds.

    Stephen Ambrose, speaking above at Autodesk's Accelerate 2016 Conference, invented in-ear monitors, an advanced earbud used by professional musicians on stages around the world. This invention became today's earbuds. When he saw the resulting damage he returned to the lab and with National Institute of Health and National Science Foundation funds solved the problem by creating a second eardrum.

    He's toured with artists like Stevie Wonder, Rush, Simon and Garfunkel, Kiss, and Diana Ross to develop his professional audio products. And today, he’s ready to help bring another innovation to market.

    Why? Because too many teens, young adults and professional musicians suffer from hearing loss today and will experience even more in the future. In fact, the proportion of teens with mild or worse hearing loss has increased 77% since the 1990s. And their studies prove the loss is due to earbud use. According the the LA Times, once hearing is damaged it will never recover.

    Fact: Earbuds cause hearing loss...

    Stephen discovered that 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.

    40 million Americans suffer from hearing loss. For 10 million Americans, the hearing loss is noise induced, not reversible and permanent.


    The Solution...


    Stephen found a way to break the cycle. It’s called ADEL™ and it’ll change the way you hear music. This technology adds a second eardrum into all of our earbuds. 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.

    Vanderbilt University study of Asius Technologies' earbud performanceActually, with ADEL™, it’s quieter – often operating at 1/10th the amplified in-ear power levels of traditional listening devices (per studies conducted at Vanderbilt University Medical Center). 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. The results from the Vanderbilt 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.

    Before sharing my personal experience, keep in mind these few points:

    I tested only the ADEL s1 auto model, on INEARZ site you can buy your custom model with different options: s1, B1, G1, manual and 01 auto model.

    I used the same black standard InEarz cable for my audio sessions

    My audio experience can be not only influenced by ADEL module, but just keep in mind, that a few mms longer ear canal for custom model, can change sound perception.

    More info about s1 auto model: Engineered to automatically tune itself to absorb the pneumatic pressures in your ear canal through a dual membrane design.

    -Noise isolation up to -18dB

    PERSONAL EXPERIENCE: I spent many time switching between IENARZ EUPHORIA standard model and with ADEL, so these are my sound impressions:

    Euphoria with ADEL, for sure, sounds more natural with a bit airier and wider soundstage. Bass has a touch less strong impact, but gains a more natural and correct reproduction. I don’t think, as stated by Asius technologies, that ADEL gives you a richer sound, but to my experience, it is capable to give you a more natural and less fatiguing experience, that most probably is due to the lack of sealed pressure in your ear canal.

    With Euphoria Adel, I can reach more satisfying pressure levels with significantly lower volumes. I usually set the volume bar of my astell and kern KANN( low gain) to 80 with EUPHORIA ADEL, on the other side I have to push the volume to 90 with standard model. Talking with Matthew of INEARZ, he explained me that ADEL doesn’t add any electrical impedance and there are no changes in tuning, so it truly allows listeners to enjoy enhanced loudness perception.

    Thanks to both EUPHORIA natural tuning and ADEL module, I found less tinnitus issues during my night audio sessions. I am not telling you that ADEL will cure your tinnitus, but can help to enjoy your audio sessions for more time and with less listening fatigue.

    Overall, both EUPHORIA ADEL and standard model are great IEMs and for sure, are among the best IEMs I have ever tested not only in this price range. There are slight sound differences, but EUPHORIA with ADEL model is able to give you a more natural reproduction, with better soundstage in all directions and with ,most important thing, a less fatiguing experience.

    INEARZ has just released their new universal models with ADEL technology: ZEN with 2 AND 4 drivers. For more info about, just follow their official site.
