Acuity Directionality is designed to improve speech protection in difficult listening situations. It’s continuously adaptive in all channels and preserves speech by utilizing independent null steering to direct the polar pattern null towards noise.

Our Acoustic Scene Analyzer will further preserve speech by reducing the effects of wind noise.

Starkey’s new ISO-Clear Compression utilizes the widest working dynamic range in the industry, providing distortion-free listening. ISO-C Compression is based on how the human ear processes sound, offering listening comfort for loud sounds and ultimate clarity for soft sounds.

In situations where the speaker is constantly moving, Acuity Directionality preserves speech by continuously adapting in all channels, utilizing independent null steering to direct the polar pattern null towards the noise.

Connectivity for today

A powerful combination of 900sync Technology, Spatial Streaming and Stream Boost is designed so patients get a quality, natural sounding hearing experience all accomplished with no intermediary device. Spatial Streaming provides your patients with the best wireless performance in all possible settings while Stream Boost provides patients with an automatic setting that boosts the incoming media stream for enhanced audio performance.

A more natural listening experience

Starkey's Binaural Spatial Mapping delivers maximum listening comfort for louder sounds while providing a more natural, overall sound. It accomplishes this by intelligently optimizing signal-to-noise settings based on estimates from both ears reducing listening fatigue. Voice IQ² is a noise management and speech preservation system intended to let patients hear effectively in noise - especially in noisy situations.

Superior audibility in noisy environments

Thanks to Acuity Directionality, our new solution to directionality, speech protection is improved in difficult listening situations. Starkey's proprietary Speech ID detects speech even when it occurs behind the patient. The combination of these two innovative technologies results in consistent, high-fidelity sound that helps patients listen to speech and participate in conversations in even the noisiest environments.

Distortion-free comfort in loud situations

Our ISO-Clear Compression delivers a more personalized listening experience by making soft speech sounds audible without affecting louder inputs. Loud sounds are discreetly managed while maintaining the quality of lower-level sounds.

Effortless connections with streaming media and accessories

SurfLink® Mobile 2, SurfLink Media and SurfLink Remote offer patients carefree connectivity and control with no intermediary or worn device. SurfLink Mobile 2 provides doubled battery life over our first generation SurfLink Mobile.

Say farewell to feedback

Starkey’s best-in-class feedback cancellation system, PureWave Feedback Eliminator has the ability to manipulate how aggressive it performs, so feedback elimination can be personalized to the specific product and patient. It’s designed to identify, classify and eliminate annoying whistling and buzzing in all environments, so your patients experience feedback-free listening from crowded cafes to serene parks.

Customizable tinnitus relief

Multiflex Tinnitus Technology is now available on the micro RIC 312 product with the release of Z series. With Z Series, Multiflex Tinnitus Technology is a wireless binaural system with synchronized user controls, providing the best comfort and control.

Laughs at water and wax

Z Series features Starkey’s proprietary moisture protection, HydraShield®². When combined with Z Series’ unibody construction, this nano-coating delivers excellent protection from water, wax and oils. The result — hearing aids that spend more time in the ear and less time being repaired.

Enjoy every conversation

Engineered to enhance real-time audibility by identifying high-frequency speech cues and replicating them in lower frequencies, Spectral iQ is unlike other technologies that apply frequency compression broadly. Z Series maintains these frequency relationships retaining sound quality while providing clarity for high-frequency speech.

Join the crowd with active noise reduction

iQ Boost is activated via our SurfLink Mobile or SurfLink Remote. This feature allows patients to aggressively reduce noise while optimizing sound quality in environments like noisy restaurants or crowded rooms.

Make constant control adjustments a thing of the past

Self Learning allows Z Series to gradually and automatically learn the patient’s personal volume preferences in each active memory. This feature reduces the number of control adjustments the patient needs to make.

Upgrades made quick and easy

The Swap Fit function lets you transfer the patient’s settings from their current Starkey product to a new one, giving you more time for counseling and fine-tuning.

Z Series offers a solution for every patient
