Adjustment BandsAdjustment BandsThese are frequency-divided sections that can be adjusted in a hearing aid in order to amplify sounds. Although there are rarely more than 10 frequencies measured in a hearing assessment, having more bands that can be adjusted may allow for improved speech understanding and user comfort.
No

Adjustment SynchronizationAdjustment SynchronizationThis feature allows for a more pleasant listening experience by ensuring that both hearing aids process sound the same way. If one hearing aid changes its processing in response to noise or speech, it will send a wireless signal to the other hearing aid so both process sound in the same way.

Automatic Phone ProgramAutomatic Phone ProgramHearing aids with this feature can detect when a phone is placed near them and automatically switch to a phone program. In this setting, the hearing aids will reduce background noise and increase the volume of the phone.
No
TwinPhoneTwinPhoneTwinPhone is the optimal solution for these wearers. It is automatically activated by a magnetic signal, so the wearer hears the caller in both ears for better understanding.
DirectionalityDirectionalityDepending on the types and number of microphones a hearing aid has, the hearing aid may be able to boost sounds from specific directions (by reducing sounds from other directions). This can be helpful to focus on a speaker directly in front of the hearing aid user, as well as to give the user information about where different sounds are coming from.
Automatic Sound FocusAutomatic Sound FocusAutomatic Sound Focus reduces surrounding noise and adjusts dual microphones toward the direction of speech.
