Like all Jrenum products, Jrenum Sport is also manufactured individually on the basis of an ear impression. The special thing is that it is partially hollow and can therefore easily absorb pressure, for example with a well-fitting helmet. Made of soft silicone, it doesn't squeeze at all - even when worn for a long time.

Note Pad

The construction is a small feat: the hearing protection is open to the outside and finds its place in the ear canal. He therefore leaves the pavilion completely free! It sounds paradoxical, but it works - even hearing a phone call is possible with this hearing protection. In addition, the built-in noise protection filter is specially designed for rapid pressure equalization, as can occur when starting an aircraft. It also filters annoying wind noise particularly well.
