Build Quality

Hearing Glasses
3.9BELOW AVERAGE

Nuance Audio Hearing Glasses have an IPX4 rating, which means they can withstand light splashes of water but may require extra care to ensure long-term reliability. Fortunately, their delicate components are less susceptible to moisture damage since they aren't positioned inside the ear like traditional hearing aids.

Multi Mic++3

The Multi-Mic+ is a versatile wireless accessory designed to help hearing aid users hear more clearly in challenging situations. It can be clipped onto clothing or worn on a lanyard to pick up a speaker’s voice and stream it directly to compatible hearing aids, or it can be placed on a table to capture group conversations in “table mode.” In addition to acting as a remote microphone, the Multi-Mic+ connects to other audio sources through a built-in telecoil, FM receiver (optional), or a standard 3.5 mm line-in cable, allowing users to stream sound from loop systems, FM transmitters, computers, TVs, or other devices. With a streaming range of up to 25 meters (82 feet), automatic mode switching, volume controls, and app integration, it provides flexible, high-quality sound input across a wide variety of listening environments

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.
No
17
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
Binaural beamformingBinaural beamformingBeamforming frequency range of 250-5000Hz.Clear FocusClear FocusFour-microphone binaural beamforming directionality with ReSound's Noise Tracker II for noise reduction.Synchronized SoftSwitching™Synchronized SoftSwitching™SoftSwitching (synchronized between ears) uses sound level and speech detection algorithms to decide when directionality is likely to be advantageous in a certain listening environment. It also offers the same four selections of MultiScope beamwidth settings: the default AutoScope, Narrow, Medium and Wide. The SoftSwitching mode differs from MultiScope Adaptive Directionality in that it uses slower transitions between directional settings and the omnidirectional setting, which is sometimes more comfortable and preferable among certain hearing aid users.

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.

Frequency LoweringFrequency LoweringUnderstanding certain speech sounds is dependent on the high frequency parts of these sounds. For individuals with high frequency hearing loss, this feature can take high frequency speech information and move it to lower frequencies where it will be audible.
No
Sound ShaperSound ShaperSound Shaper is the only frequency compression technology that moves high-frequency sounds down in the spectrum while maintaining a proportional relationship between input and output frequencies. So Sound Shaper improves the audibility of speech cues that would otherwise be lost, while maintaining the best sound quality possible.

Yes
NoiseTracker™ II: 5 settingsNoiseTracker™ IINoiseTracker II uses a technology called spectral subtraction. Spectral subtraction works by subtracting the short-term noise spectrum from the signal, leaving only the speech portion behind ... ReSound’s NoiseTracker II is able to use spectral subtraction successfully because the Environmental Classifier has identified speech and noise so precisely.
Sudden Loud Noise ReductionSudden Loud Noise ReductionThis feature detects loud sounds and reduces their volume to a comfortable level. Though not a replacement for hearing protection, this technology can greatly improve listener comfort.

Tinnitus ReliefTinnitus ReliefTinnitus, or ringing in the ears, can be addressed by hearing aids in several different ways, such as introducing a soft therapeutic signal or targeted notched noise.
No
Tinnitus Sound GeneratorTinnitus Sound GeneratorThe tinnitus sound generator administers sounds that make the disturbing noise less noticeable and draw your attention away from the tinnitus.
Wind Noise ReductionWind Noise ReductionAs wind blows against the microphones of hearing aids, unpleasant noise may be generated. Some hearing aids have the ability to recognize this wind noise and reduce its level. Such reductions may also affect the audibility of desired sounds, like speech.
No
Wind Guard: 3 settingsWind GuardWhen no wind noise is found, the hearing aid constantly updates and stores the sound input levels in each Warp band. Then, when wind is present, WindGuard calculates the amount of gain reduction needed to return to the stored level of the specific bands affected by wind noise.
