Powered by a standard zinc-air 312 battery (about 185 mAh), the Nexia 61 typically delivers around 140 hours of listening on a single cell. That equates to roughly six days of normal use, including a few hours of streaming calls or music each day. When the cell runs low, swapping in a fresh 312 takes only seconds and requires no charging gear, ideal for anyone who wants uninterrupted wear over several days without pausing to recharge.

ReSound Nexia hearing aids are among the first to support Bluetooth Low Energy (LE) Audio and Auracast™, marking a significant advancement in wireless connectivity. Bluetooth LE Audio offers high-quality audio streaming with lower power consumption, extending battery life while maintaining excellent sound fidelity. This ensures that users can enjoy prolonged streaming of music, calls, and other audio content without frequent recharging . 

Auracast™ introduces a new dimension to public audio broadcasting by allowing hearing aids to connect directly to audio streams in public venues equipped with Auracast transmitters. This includes places like airports, theaters, and conference centers, where users can tap into live audio feeds for announcements or performances, enhancing accessibility and engagement in communal settings. 

These connectivity features are available across all ReSound Nexia technology levels (NX9, NX7, NX5) and are supported in all device types, including microRIE, RIE 312, and RIE 13. The integration of Bluetooth LE Audio and Auracast™ positions ReSound Nexia as a future-ready solution, catering to the evolving needs of users in an increasingly connected world. 

Noise Tracker II is an advanced noise reduction system in ReSound Nexia hearing aids that employs spectral subtraction to minimize background noise without compromising speech clarity. By analyzing the incoming sound signal, the system distinguishes between speech and noise, effectively reducing unwanted ambient sounds while preserving the integrity of speech signals. This enhances listening comfort in various environments, from quiet settings to noisy gatherings . 

The feature offers different levels of noise reduction based on the technology level: NX9 provides five settings, NX7 offers three, and NX5 includes two. This allows for personalized adjustments to match the user’s specific listening preferences and environments. By tailoring the noise reduction intensity, users can achieve an optimal balance between comfort and awareness of their surroundings. 

The Tinnitus Sound Generator (TSG) in ReSound Nexia hearing aids offers a range of customizable sound therapy options to alleviate the symptoms of tinnitus. Users can choose from various masking sounds, including white noise and nature-inspired sounds like ocean waves or soft rain, to distract from the perception of tinnitus and promote relaxation . 

TSG settings can be personalized through the ReSound Smart 3D app or by a hearing care professional, allowing adjustments to the volume, frequency, and type of masking sound to suit individual preferences and tinnitus characteristics. This personalized approach enhances the effectiveness of tinnitus management and supports overall well-being. 

The TSG feature is available across all ReSound Nexia technology levels (NX9, NX7, NX5) and device types, including microRIE, RIE 312, and RIE 13. By integrating tinnitus management into the hearing aid, users benefit from a comprehensive solution that addresses both hearing loss and tinnitus symptoms in a single device.
