A hearing by the audiologist, or hearing care will turn out more and more powerful by the individual adaptation, as a hearing aid off the shelf. But there are also good reasons to choose the simple and cheap solution. Not everyone who hears badly wants to multiple sessions the audiologist or audiologist. For all those people who look only, eg for the home, need a hearing aid to TV, or in to entertain familiar surroundings, this unit is sufficient to my understanding anyway. The unit is supplied in a storage case. As an accessory, a charger, and several interchangeable Hörstöpsel still exist. The hearing aid has a on-off switch, a volume control, and a lockable mini socket for connection of the charging cable. It can be added that the device sits discreetly in the ear. I get along well with the hearing aid.
