PHONAK Audéo PFE Audio filters

Audio filter box with 8 audio filters + 1 changing tool.

The easy-to-replace, passive audio filters adapt the frequency response to your individual listening preferences and provide crystal clear, luscious sound.

The purpose of this filter is to provide you with the best quality sound that matches what you would hear naturally when not wearing ear tips. Hearing differs significantly from one person to another, and unlike standard earphones, Audéo PFE allows you to select the filter that works best for you.

The filters also protect the sound tubes from filling with dirt. This significantly extends the lifetime of your earphones.

The black audio filters provide stronger bass and treble. The grey audio filters provide stronger middle tones.
