Note from the Audiologist: Siemens is now transitioning their name to Signia. They are well known for their quality products. They pioneered communication between 2 hearing aids, and have evolved this to the point that the hearing aids or the user can direct the focus of the hearing to the sides, behind, or in front. The "narrow directionality" and "spatial speech focus" is what finally allowed them break through a landmark barrier and make the claim, "Clinically proven to exceed normal hearing in difficult listening situations." Their current hearing aids do really well in moisture and dust. They come in a variety of sizes from behind the ear to in the ear. Their new product is called Primax and has all the same features as the binax with improvements in echo and wind.
Siemens/Signia also private labels and locks their hearing aids for Miracle Ear. A locked hearing aid can only be programmed by the business it was bought at. In the case of Miracle Ear, any Miracle ear dealer should be able to adjust the hearing aid, but they will not or can not unlock the hearing aid for any other hearing care provider to adjust.
*Two clinical studies have shown that binax provides better than normal hearing in certain demanding environments (University of Northern Colorado, 2014; Oldenburg Hörzentrum, 2013): Speech Reception Thresholds (SRT) in cocktail-party situations improved up to 2.9 dB for wearers with mild to moderate hearing loss using Carat binax or Pure binax hearing aids with narrow directionality, compared to people with normal hearing.
