UltraZoom: Creates a highly focused directional microphone beam in front of the wearer using binaural processing, available exclusively on rechargeable Infinio models.

NoiseBlock (Limited settings): A limited-configuration version of Phonak's NoiseBlock feature for the Terra platform, providing steady-state background noise reduction with fewer adjustment parameters than the full NoiseBlock available in higher-tier platforms.

QuickSync: Wirelessly synchronises volume and program changes between the left and right hearing aids, so adjusting one aid instantly mirrors the change on the other without the patient needing to touch both.

WhistleBlock: Continuously monitors for and eliminates acoustic feedback (whistling) before it becomes audible, using advanced prediction to cancel the feedback path.

Broadband Booster: Provides additional high-frequency amplification specifically for wearers using UP (Ultra Power) BTE receivers, helping those with profound high-frequency loss access more high-frequency sound.

Environmental balance: Adjusts the balance between speech amplification and environmental/background sound, allowing the fitting to be tuned so the patient maintains natural awareness of their surroundings while speech remains primary.

User Preference Tuning: Allows audiologists to incorporate the patient's own sound preferences into the fine-tuning process, adjusting the fitting based on feedback from the wearer rather than solely on target-matching algorithms.

Auto Acclimatization: Automatically increases amplification progressively over a set period after fitting, allowing new hearing aid wearers to adjust gradually to full prescription levels rather than receiving the complete target gain from day one.

SoundRecover: The original Phonak frequency lowering technology that compresses inaudible high-frequency sounds into a lower frequency region where the patient has residual hearing.

AutoSense OS™ 5.0 (Limited): A limited version of Phonak's AutoSense OS 5.
