B3 are relatively small and have a modern receiver-in-canal design. One potential downside is that they are currently only available in a mat grey color.

Lithium-ion

TelecoilTelecoilThe hearing aid is able to pick up audio from landline telephones or public audio systems without using its acoustic microphones. This minimizes background noise and improves clarity and understanding, even over great distances. At performing arts venues, events, government meetings, etc., look for assistive listening systems (hearing loop, FM, and infrared systems), which must be provided at no cost under the Americans with Disabilities Act (ADA) and other international regulations.

Software Features

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.

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.

Yes

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.

Yes

Bass BoostBass BoostExtra amplification for lower tones.

Low Frequency Boost: Basic

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.

Yes

Environmental AdaptationEnvironmental AdaptationThe hearing aid can detect different acoustical environments, like speech in noise, and adjust the sound of the hearing aid accordingly to drive comfort or speech understanding, etc.

Yes

ExpansionExpansionExpansion reduces audibility for very soft sounds. This can help to remove microphone noise, which is generated by soft environmental sounds.

On/Off

Feedback SuppressionFeedback SuppressionIf any sound amplified by the hearing aid escapes the ear canal, it may reach the hearing aid’s own microphone and cause a harsh whistling noise. Some hearing aids are able to recognize when this feedback occurs and reduce or eliminate it.
