The 2UUL DA32 is an ultra-thin adhesive mesh sticker used to protect the microphone hole of smartphones and other electronic devices. It acts as a barrier against dust, moisture, wind, and debris, while still allowing sound to pass through clearly.
It is commonly used by repair technicians or in aftermarket phone repair to reseal or protect the mic opening after a device has been opened.
Dust & Debris Protection: Helps prevent dust, dirt, lint, and small particles from entering the mic hole.
Moisture / Liquid Resistance: Offers a barrier against liquid ingress (splashes, humidity) to some degree.
No Sound Impairment: The ultra‑thin design ensures sound can pass through with minimal distortion or attenuation.
Residue‑Free Removal: Claimed to leave no sticky residue when removed, which is important in repair work.
High Temperature Tolerance: Useful in repair environments (e.g. near heating elements) without degradation or residue.
Economical for Bulk Use: Comes in 500‑unit packs, making it practical for repair shops or technicians.
Clean the Mic Area: Before applying, ensure the microphone hole rim is clean, free of dust or residue.
Align Carefully: Place the sticker over the mic hole, aligning it centrally to avoid blocking or shifting.
Press Gently: Use light pressure to adhere it, ensuring full contact at the edges.
Test Audio: After application, test sound / mic performance to ensure no degradation.
Removal / Replacement: Peel gently from one edge when needed; if reusing (though generally use fresh), ensure no adhesive is left behind.
Storage: Keep unused stickers in a dry, dust‑free container to avoid contamination.
