Last Updated on August 25, 2025 by Jonathan Javid Au.D.

Bluetooth-enabled hearing aids are among the most advanced assistive listening devices available today. They not only enhance your ability to hear in everyday life but also connect seamlessly with digital devices for a richer, more convenient listening experience. But exactly what does a Bluetooth-enabled hearing aid do, and how can it improve your quality of life? Let’s explore the key features and benefits.

Core Functions of Bluetooth Hearing Aids

1. Direct Streaming from Your Smartphone
2. Hands-Free Calling
3. Binaural Music and Audio Streaming
4. Mobile App Control
5. ‘Find My Hearing Aid’ Feature

1. Direct Streaming from Your Smartphone

In today’s digital age, we rely on smartphones for calls, entertainment, and information. A Bluetooth-enabled hearing aid can connect directly to your phone, streaming sound straight into your ears. This allows you to hear calls, podcasts, audiobooks, and videos with clarity—without disturbing others or switching between devices.

2. Hands-Free Calling

Bluetooth hearing aids make phone calls simple and clear. When you receive a call, audio streams directly to your hearing aids, and built-in microphones transmit your voice to the caller. Many models let you answer calls with a simple button press or tap—no phone handling required.

3. Binaural Streaming for Music and Audio

For music enthusiasts, binaural streaming sends sound to both hearing aids simultaneously, creating an immersive stereo effect. This feature enhances the quality of music, podcasts, and audiobooks—making them richer and more enjoyable.

4. Mobile App Control and Customization

Most Bluetooth hearing aids work with companion apps, such as those found in our guide to the best-rated hearing aid apps. These apps let you adjust volume, change listening programs, and even connect with your audiologist for remote programming—allowing for real-time adjustments without visiting a clinic.

5. ‘Find My Hearing Aid’ Feature

Misplacing a hearing aid can be stressful, but modern models often include a ‘Find My Hearing Aid’ function. Through the companion app, you can trigger an audible alert from your device or view its last known location on a map, making it much easier to recover.

Advanced & Lesser-Known Bluetooth Hearing Aid Features

Some brands, like the Starkey Genesis AI, take Bluetooth capabilities even further with advanced features such as:

1. Fall Detection & Alerts – Automatically notifies a contact if you fall, improving safety for older adults or those with balance concerns.
2. Integration with Voice Assistants – Works with Siri, Alexa, or Google Assistant for hands-free commands and information.
3. Voice-to-Text Transcription – Converts speech to text in real time, perfect for noisy settings.
4. Language Translation – Offers real-time translations, helping bridge language gaps.
