Will this work with my headphones or hearing devices?
This transmitter works with compatible Auracast headphones, speakers, and hearing devices. Not all hearing aids models are supported, so please check the compatibility list in the images. For Auracast hearing device users, we recommend Audikast 4HA.
Can I share TV audio with two (or more) people at the same time?
Yes, in Auracast mode you can broadcast to multiple compatible receivers at once. In classic Bluetooth mode, the transmitter can connect to only one device at a time.
My TV has no optical or AUX port, can I still use it?
This transmitter needs an optical or AUX audio output from your TV. If your TV doesn’t have either, it may not be compatible. Please check your TV’s available audio outputs before purchase.
Will this help me hear TV dialogue more clearly without raising the volume?
Yes. This transmitter lets you listen through compatible headphones or assistive listening devices at your own volume, without increasing TV speaker volume. Many users find dialogue clearer and more comfortable, especially for long TV sessions.
Why choose this instead of a regular Bluetooth TV transmitter?
This transmitter supports the latest Auracast technology and is designed to stay compatible as Auracast devices continue to evolve. With firmware upgrade support, it’s built for long-term use and future audio-sharing needs.
