Explanation by manufacturer

Adopt an absolute polymer that changes shape depending on body temperature

For the first time in the world, an “absolute” material that blends softly with human skin was adopted as earpieces. Depending on your body temperature, the earpiece will deform according to the shape of your ear hole. It reduces excessive resilience, and since it can be worn with little feeling of compression, it minimizes wearing fatigue and pain due to prolonged use such as watching music or watching videos or teleworking.

(above) It looks like it was combined with the “ATH-TWX9.” Regarding wearability, conventional earpieces that can be attached to all true wireless earphones sold by Audio-Technica so far (bottom) return quickly even if the shape changes, but the AT-ER500 has the characteristic that changes are maintained for a while

Product Review by PHILE WEB (File Web) Pro An easy-to-use earpiece with a new sense of comfort and tone changes The shape of the AT-ER500 is the shape of a shaft and umbrella, similar to general silicone earpieces, but the texture is different from silicone and existing thermoplastic elastomer systems. First of all, it is harder than those at room temperature, and you can feel its hardness when you put it in your ear and immediately after putting it in. The new feeling is that it feels firmer than before and disappears after a while in the ear. The change that stands out particularly well in combination with the ATH-TWX9 is on the high range side. While softening the feel of the sound slightly, it does not impair the clarity of the sound image and localization, but even enhances it. Changes on the bass side were felt more strongly in the ATH-CKS50TW. In the Robert Glasper Experiment “Human,” which includes everything from ultra-low to low frequencies, the sense of volume of bass and bass drums first increased dramatically. What's important is from here, and that bass doesn't become so saturated. This change should only resonate with fans of deep bass phones!

Only geeky earphone fans will find it worthwhile to use this unprecedented change in tone. On the other hand, this unprecedented fit should be easy to understand, even for those who are trying to exchange earbuds for the first time. Whichever you are, it's a model worthy of attention.

To request a return or exchange, please note that it is mandatory to provide a video of the unpacking of the package.
