Which Hearing Aids are Auracast Compatible?
Auracast for Hearing Aids in Yorkshire
Auracast is a major upgrade to standard Bluetooth technology. Instead of forcing a audio device to pair with just one pair of headphones or hearing aids at a time, Auracast works like a miniature radio station. One transmitter broadcasts crystal-clear audio through the air to any number of nearby hearing aids or compatible headphones at once.
Why Auracast Matters
Traditional Bluetooth was built for one-to-one connections (like connecting your phone to a single speaker). That design creates three big headaches for hearing aid wearers:
-
Short Range: Standard Bluetooth drops out if you walk more than ~30 feet away from the TV or laptop.
-
Audio Delay (Latency): Standard Bluetooth takes roughly 150 to 250 milliseconds to process sound. That tiny delay causes a distracting “lip-sync” lag where people’s mouth movements don’t match what you hear.
-
Exclusive Pairing: Only one person can stream audio at a time, making shared TV watching or group listening difficult.
Auracast fixes all three:
It broadcasts to unlimited listeners, drops audio delay down to 50–70 milliseconds (virtually instant), and extends coverage up to 300 feet (100 meters) in open spaces.
How It Helps Hearing Aid Users
-
No More Lip-Sync Lag: TV dialogue feeds directly into your hearing aids at the exact instant actors speak, eliminating muffled dialogue and echoes from room acoustics.
-
Shared Family Listening: You can listen at your preferred volume straight through your hearing aids while family members listen through standard TV speakers or extra Auracast headphones — at whatever volume is comfortable for them.
-
Zero-Hassle Connection: You don’t have to navigate confusing phone menus or unpair devices. You simply tune your hearing aids into the broadcast signal and instantly start listening.
-
Freedom to Move Around: Because long-range transmitters cover up to 300 feet, you can walk into the kitchen to grab a drink without losing TV audio or missing a sentence.
Why Buy an Auracast Transmitter for Your Hearing Aids?
While newer hearing aids come equipped to receive Auracast signals, most TVs, computer monitors, and gym equipment don’t have Auracast built into them yet. An Auracast transmitter plugs directly into your existing devices and turns them into Auracast broadcasting stations.
Avantree offers specialized transmitters tailored to how you use your devices:
| Transmitter Type | Best For | Key Advantage |
| TV Transmitters (e.g., Audikast 4HA / MediaCast) | Living room TVs & home entertainment | Plugs into Optical or HDMI ARC outputs; optimized specifically for Auracast hearing aids. |
| Portable / AUX Transmitters (e.g., Voyager HA) | Gym treadmills, airplane screens, portable audio | 3.5mm plug with an OLED screen to easily select broadcasts on the go. |
| USB-C Transmitters (e.g., C82 Aura) | Laptops, tablets, and computers | Plug-and-play USB connection for clear audio during videos, webinars, or streams. |
| Long-Range Transmitters (e.g., Oasis Aura) | Large homes, classrooms, or community rooms | Maximum range (up to 300 ft) to cover wide spaces without signal dropouts. |
Adding an Auracast transmitter bridges the gap between your modern hearing aids and your home electronics — giving you custom, lag-free audio without replacing your existing TV or computer setup.
