Why Doesn’t My LE Audio Headphone Work with the Avantree Transmitter?

LE Audio is a new Bluetooth technology that offers better sound quality and improved battery life. But because it’s still very new, many devices aren’t fully compatible yet — and not all LE Audio features are the same.

When you see a device that supports LC3 or LE Audio, it’s important to know whether it supports:

• Auracast (one-to-many)

• or One-to-one LE Audio (like classic Bluetooth pairing)

Two Types of LE Audio Connections:

✅ Auracast (One-to-many broadcast mode):
This allows one device to stream audio to many headphones at the same time — great for group listening.

• Avantree Auracast transmitters work well with most Auracast-enabled headphones and hearing aids.

• ⚠️ At this time, JBL Auracast speakers are not supported.

⚠️ One-to-one LE Audio (like traditional pairing):
This is great for gaming, video, and calls, offering lower latency and better sound when the mic is on.

• However, this type of connection is still inconsistent across brands, and

• Avantree transmitters currently only support our own LE Audio headphones in one-to-one mode.
