Resound nexia 4 ITC forTechnical Specifications at a Glance: 

1. The Advantage of Custom-Molded Precision

Unlike “one-size-fits-all” devices, the ReSound Nexia 4 ITC is crafted from a high-resolution 3D impression of your ear canal. This results in:

• Invisible Discretion: The ITC style sits comfortably within the ear canal, making it nearly invisible to those around you.

• Physical Comfort: Because it is molded to your ear, there is no pressure or discomfort, even during 16+ hours of continuous wear.

• Acoustic Integrity: By placing the microphone inside the ear, the device uses your outer ear (pinna) to naturally localize sound, helping you tell exactly where voices are coming from.

2. Future-Ready Connectivity with Auracast™

The Nexia 4 is one of the world’s first hearing aids ready for Bluetooth® Low Energy (LE) Audio and Auracast™. This is not just a feature for today; it is a gateway to the future of public sound.

• Direct Streaming: Stream high-quality audio from iPhones and compatible Android devices (ASHA) with lower battery consumption than traditional Bluetooth.

• Hands-Free Calls: Use your hearing aids as a wireless headset. The Nexia 4 picks up your voice and sends it to your phone, allowing you to stay connected while keeping your hands free.

• The Auracast Revolution: In the coming years, theaters, airports, and sports arenas will broadcast audio via Auracast. With the Nexia 4, you can “join” these broadcasts directly, bypassing background noise entirely.

3. Superior Performance in Noise

The Resound nexia 4 ITC technology level features 12 Warp Processing Channels, which allow the device to analyze and adjust sound with surgical precision.

• 150% Better Speech Understanding: Clinical data shows that the Nexia platform significantly improves the ability to hear speech in loud environments, such as busy restaurants or family gatherings.

• Adaptive Directionality: The microphones automatically switch focus to the person speaking in front of you while subtly suppressing the distracting noise behind you.

• Natural Soundscape: ReSound’s Organic Hearing philosophy ensures that environmental sounds—like birds chirping or the hum of a fan—remain audible but never overwhelming.

4. Hassle-Free Rechargeability & Custom Charging

Forget the struggle of tiny, disposable batteries. The Nexia 4 ITC features a long-lasting lithium-ion battery.

• All-Day Power: Enjoy up to 24-30 hours of use on a single 3-hour charge. Even with heavy streaming, you can rely on a full day of performance.

• The Custom Charger: Because every ITC is a different shape, ReSound provides a charger with inserts specifically molded to match your devices. This ensures a secure magnetic connection and a consistent charge.

• Quick Charge: In a hurry? A 10-minute “quick charge” provides up to 3 hours of battery life.

Nexia 4 ITC Frequently Asked Questions (FAQ)

Q: How is the Resound nexia 4 ITC different from the Nexia 5, 7, or 9? A: The Nexia 4 is the essential premium tier. While it shares the same physical design and Auracast technology as the higher tiers, the 5, 7, and 9 models offer more processing channels (up to 17) and more advanced automated noise-reduction features for extremely complex environments.

Q: Is the ReSound Nexia 4 ITC truly waterproof? A: It is rated IP68, which is the highest industry standard for water and dust resistance. While we don’t recommend swimming with them, they are fully protected against sweat, rain, and accidental brief submersion.

Q: Do I need a special phone to stream music and calls? A: The Nexia 4 is compatible with most modern smartphones. It supports Made for iPhone (MFi) and Android Streaming (ASHA). For the newest Bluetooth LE Audio features, you will need a device that supports Bluetooth 5.3 or later.

Q: Why do I need a “Custom” charger? A: Unlike standard hearing aids, the shape of an ITC (In-the-Canal) device is unique to your ear. A standard charger wouldn’t be able to hold the device securely against the charging pins. The custom charger has inserts 3D-printed to match your specific ear molds perfectly.

Q: How long does the battery last? A: On average, you can expect 24 to 30 hours of use. If you are streaming audio for more than 5 hours a day, the battery will typically last about 20-22 hours, which is still more than enough for a full waking day.

Q: Can these hearing aids help with Tinnitus? A: Yes. The Nexia 4 includes built-in Tinnitus Sound Generator (TSG) features. Using the ReSound Relief app, you can customize “white noise” or “ocean sounds” to help mask the ringing in your ears.
