EF-4, the universal hearing protector

The EARfoon EF4 is a universal hearing protector shaped in such a way that it fits in any ear and is immediately ready for use.  The filter makes it possible to supply the EF4 in two different noise reduction models, both of which guarantee good noise reduction whilst maintaining the wearer’s ability to understand speech.  The low price and the fact that it is ready for use make the EF4 ideal for temporary workers and private customers wishing to use the EF4 under various conditions.

The EF4 is available in a (long) model with a cord and a (short) model and is supplied in a handy case.
