This is a 1-way, water resistant unit, that is rechargeable via a USB cable. The earbuds are
replaced by custom earmolds made to fit your ear canal exactly. They also prevent most
engine noise from being heard. Ideal for engine forward inboards where noise is a problem.
My experience in the Lauterbach Special says this is the unit to have but not everyone needs it.
