Can I use the earbuds with other devices, and how?

The Audikast Plus transmitter and the Ace 130 earbuds included in the HT4130 set can be used independently. Just make sure that if you use one, you need to turn off the other one. e.g. If you want to pair the transmitter with other headphones, you need to put the Ace 130 earbuds in the charging case and close the case. Then enter the transmitter into pairing mode.

Here's how to use the Ace 130 earbuds with your Mobile Device instead:

Step 1: Refer to the following link and Enter Pairing Mode on the Avantree Ace 130.

Step 2: Connect/Pair the Headphone to Bluetooth on Your Device.

On your device, locate the Bluetooth settings and make sure that Bluetooth is turned on. Find the headphone  “Avantree Ace 130” and select it to pair them up.

Once connected, the LED on the headphones will occasionally flash BLUE and the headphones will show as connected on your device. The voice prompt will say "Connected" to indicate connection.
