From Audicus' website:
The Audicus Dia II is a highly versatile Behind the Ear (BTE) digital hearing aid for all your hearing needs. Its award winning, discreet hearing aid design, combined with its ability to accommodate up to severe hearing loss, makes it an option for nearly anyone looking for a behind the ear hearing aid. With two directional microphones, eight channels, and advanced signal processing, the Dia II BTE hearing aid is equipped to drown out background noise and amplify speech. It features auto-adapt technology to work in a host of listening environments, as well as four volume programs for maximum control. This is the top discreet hearing aid on the market today.
While the company does technically offer remote adjustments by a licensed audiologist, there is a bit of a process involved. This is important for consumers to factor in when purchasing from Audicus, especially if you really can't be without your device(s):
If you are not completely happy with the programming, or if your hearing loss changes over time, please fill out our reprogramming survey and send your hearing aids to our office. Our audiologist will review the issues you’re having and adjust the programming for you ... Our audiologist will reprogram the hearing aid within 1-2 business days from when it’s received. We will pay for the shipping back to you.
The Audicus Dia II has water resistant coating, disposable batteries, directionality, feedback suppression, processing channels, noise reduction, adjustment synchronization, and environmental adaptation.
