Blues Series
Blues Hearing Aids are manufactured with the use of Open Fit technology. The main point of Open Fit technology is that the traditional ear mold which tightly closes the ear cannel is changed to a vented ear mold equipped by a number of vents and places inside the ear. The advantage of such ear molds is that the ear remains open, can easily breathe, doesn’t sweat and doesn’t get tired after using the hearing aid. Owing to the vents in the ear mold the ear cannel doesn’t get closed and as a result you can hear your voice directly but not through the receiver. The sound remains natural.
The use of Open Fit technology prevents occlusion effect in other words stuffiness in ear. Occlusion effect while using the hearing aid can occur because stuffiness in the ear cannel brings out excessive amplification of low-frequency sounds particularly the sound of your own voice. The vented ear molds do not block the ear cannel and due to this the feeling of stuffiness in ear and echo effect does not appear. Sufficient peculiarities of this type of hearing aids are maximum density and size-conscious design. Hearing aids of Blues product line ideally suite to people with mild type of hearing loss.
