Blow Some Minds

New GORE® Acoustic Vents for Optimum Earbuds Design: Smaller Size, Better Sound.

Traditional earbud designs relying on open holes or woven mesh often do great in labs and out-of-the-box but leave earbuds vulnerable to contaminants that degrade performance and lifespan. To prevent this, leading earbud manufacturers turn to GORE® Acoustic Vents in search for a unique combination of uncompromised audio and enhanced durability.

New GORE® Acoustic Vents GAW348 and GAW350 meet this demand with a mind-blowing balance of protection, size and sound.

Give Your Customers What They Want: Innovation for Miniaturization

Consumers have clear priorities when it comes to earbuds: They want smaller size, better sound and robustness for everyday handling. But as earbuds shrink to accommodate new features, design teams struggle to maintain sound quality with traditional vents. With GAW348 and GAW350, Gore steps up to the challenge, delivering exceptional acoustics in smaller spaces.
