Westone WM25 Filter

No, these filters are specifically engineered to fit the Westone TRU series hearing protection systems. They will not fit or function correctly with other earplug models.

The 21dB Noise Reduction Rating (NRR) indicates that these filters reduce the volume of incoming sound by an average of 21 decibels. This level is generally effective for protecting your hearing in moderately loud environments, such as concerts or noisy workspaces, while still allowing you to hear music and speech clearly.

If your earplugs are still in good condition but the sound quality has degraded or the filters are damaged, you only need to replace the filters. This is a cost-effective way to refresh your existing gear and maintain consistent sound reduction.

The clear covers are designed to snap over the filters to keep them securely in place and protected from debris or moisture. They ensure the filter remains clean and functional during active use.

These filters are designed to provide high-fidelity sound reduction, meaning they aim to lower the volume evenly across frequencies rather than muffling the sound. If your current filters are worn out, replacing them with these should restore the original, balanced sound quality you expect from your TRU series earplugs.
