Augmented Focus: Processes background sound separately from speech focus streams, keeping ambient sound comfortable and immersive while foreground speech is enhanced.

Focus Stream: Enhances speech signals coming from the front hemisphere of the listener, concentrating amplification on the most likely speech direction during conversations.

Surrounding Stream: Processes environmental sounds to preserve the patient's awareness of what is happening around them without allowing those sounds to mask speech.

Dynamic Soundscape Processing 3.0: Integrates inputs for precise hearing aid optimization including (when available) acoustic sensors, motion sensors, CVP 2.

SpeechStabilizer: Preserves the natural envelope of speech in any situation including very noisy situations, preserving the acoustic cues that are most important for speech understanding.

Speech and noise management: Distinguishes between speech signals and background noise and differentially amplifies speech while reducing noise, improving the signal-to-noise ratio the patient experiences.

Automatic directionality: Automatically switches between omnidirectional and directional microphone modes depending on the noise level detected, without the patient needing to select a program.

eWindScreen™: Detects wind noise on the microphone and reduces it in real time, preventing the 'rushing' sound that occurs outdoors from masking speech or causing discomfort.

Signia app: Allows the patient to adjust volume, programs, and sound settings directly from their smartphone, and may enable remote support from their audiologist.

miniPocket compatibility: The aid is compatible with Signia's miniPocket remote control device, allowing patients who prefer a physical button to adjust their aids without a smartphone.

e2e wireless 4.0: Controls coupling, synchronization, CROS/BiCROS pairing, and a range of sound features between both hearing aids via Signia's fourth-generation binaural wireless link.

Adaptive Streaming Volume: Automatically adapts the streaming volume of audio (phone calls, music) depending on the level of ambient noise, so streamed audio stays intelligible without manual volume changes.

TeleCare: Provides remote services including the TeleCare Dashboard, Remote Fine Tuning, and CareChat, allowing audiologists to make adjustments and communicate with patients without an in-person visit.

HandsFree: Enables the wearer to answer calls hands-free by picking up the caller's voice via the hearing aid's own microphone and streaming it to the connected device, available via Bluetooth Classic, MFi, or LE Audio.

CallControl: Allows calls to be answered and ended by pressing the hearing aid button, with the audio handled depending on hearing aid model and connection type.

Telecoil: Enables direct connection to audio loop systems and compatible telephone signals, allowing the patient to pick up sound directly from hearing loops in public venues.

TV Sound compatibility: Streams high quality stereo sound directly from a TV to the hearing aids via Bluetooth, allowing the patient to set their personal hearing aid volume without raising the TV volume for everyone else.

Extended dynamic range: Allows the aid to process both very soft sounds and very loud sounds accurately within the same environment, preserving the natural loudness differences between sounds.

Feedback cancellation: Detects and eliminates the whistling or squealing sound (feedback) that can occur when amplified sound leaks back into the microphone, before the patient or those around them even hear it.

SoundSmoothing™: Detects and instantly softens sudden sharp sounds (such as clattering cutlery, clapping, or keyboard clicks) before they reach the ear, reducing listening fatigue and discomfort.

TruEar 360: Reproduces the benefits of the natural pinna effect by highlighting the difference between front and back sources of sound, giving the patient accurate spatial awareness in all directions.

Notch Therapy®: Signia's unique, patented tinnitus therapy which is proven especially effective against tonal tinnitus by selectively reducing amplification at the tinnitus frequency to reduce its neural reinforcement over time.

Signia Assistant: Offers wearers instant 24/7 troubleshooting and customized sound adjustment recommendations via an intuitive AI-enabled chat in the Connex app, providing detailed information to address each client's fine-tuning needs.

InSituGram: Performs a hearing threshold measurement directly through the hearing aid while it is sitting in the patient's ear, enabling audiologists to calibrate the fit without a separate audiometric booth test.

AutoFit: Automatically calculates and applies an initial fitting prescription based on the patient's audiogram, giving the audiologist a ready-to-fine-tune starting point without manual entry.

Smart optimizer & Data logging: Automatically records how and where the patient uses their aids (which programs, how long, at what volumes), giving audiologists objective data to guide follow-up adjustments.

Frequency compression: Compresses high-frequency sounds (such as consonants like 's' and 'f') into a lower frequency range where the patient has more residual hearing, improving speech clarity when high-frequency amplification alone is insufficient.

Automatic acclimatization manager: Automatically increases amplification gradually over a set period after fitting, allowing new wearers to adjust to hearing aid amplification progressively rather than receiving the full target level from day one.

CROS/BiCROS compatibility: Allows the hearing aid to work as part of a CROS or BiCROS system, where a transmitter on the non-aided ear sends sound to the hearing aid on the better ear.
