Earbud & Headphone Nozzle Mesh is used for covering the sound nozzle of earbuds and the driver opening of headphones so earwax and debris stay out while the high-frequency response is tuned. IEC 60268-7 is the reference cited for it on drawings, datasheets and purchase orders.
What IEC 60268-7 Means for Earbud & Headphone Nozzle Mesh
The dimensions in the table below are supplied to suit IEC 60268-7. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

Specifying Earbud & Headphone Nozzle Mesh Beyond the Standard
- Nozzle fit: Match diameter to the nozzle bore (commonly 4.5–6.5 mm) and specify flat or domed.
- Acoustic damping: The mesh Rayl value sets how much the 6–10 kHz peak is softened; quote the frequency response target.
- Color & finish: Black oxide or PVD makes the mesh visually disappear behind tinted housings.
When Earbud & Headphone Nozzle Mesh Is Not the Right Choice
Not a medical-grade hearing-aid wax filter, which uses dedicated disposable filters approved for the device.
