Dual-Link Troubleshooting

Can't Connect Two Headphones to Your Audikast?

Follow the pairing order below. Connect the first headphones completely before starting the second connection.

Keep Headphone 1 connected.

Do not disconnect the first headphones when you begin pairing the second headphones. The first connection should stay solid blue.

Before You Start

These quick checks help prevent another device from taking the connection.

Turn Off Nearby Bluetooth

Temporarily turn Bluetooth OFF on your TV, phone, tablet, or computer if they were previously connected to either pair of headphones.

Use True Pairing Mode

Both headphones must be ready for a new Bluetooth connection. Simply powering them on is not enough.

Keep Devices Close

Keep the headphones and Audikast close together while pairing.

Pair in This Order

Do not move to the next step until the previous connection is complete.

Headphone 1 Pair with A / 1

1 Solid Blue First connection complete

Headphone 2 Pair with B / 2

1 + 2 Solid Blue Both listeners connected

Connect the First Headphones

Finish this connection completely before pairing Headphone 2.

Put Headphone 1 in Bluetooth pairing mode.

Follow the headphone manufacturer's pairing instructions.

Start pairing on the Audikast.

Press and hold the A / 1 pairing button for 5 seconds.

FLASHING RED + BLUE The first Audikast connection is searching.

Wait for Headphone 1 to connect.

Keep the devices close and allow them to connect automatically.

SOLID BLUE Headphone 1 is connected.

Do not start pairing Headphone 2 until the first connection is solid blue.

Add the Second Headphones

Leave Headphone 1 connected while you pair the second set.

Put Headphone 2 in Bluetooth pairing mode.

Make sure it is not still connected to a nearby phone, tablet, TV, or computer.

Start the second Audikast connection.

Press and hold the B / 2 pairing button for 5 seconds.

FLASHING RED + BLUE The second Audikast connection is searching.

Wait for Headphone 2 to connect.

Keep the first headphones connected and wait for the second connection to complete.

1 + 2 SOLID BLUE Both listening devices are connected.

Success: both listeners should now be able to hear the same TV audio.

Still Having a Dual-Link Problem?

Choose the situation that best matches what you see.

Headphone 2 won't connect

Keep Headphone 1 connected.
Turn Bluetooth OFF on nearby devices that may reconnect to Headphone 2.
Restart Headphone 2, then put it back into Bluetooth pairing mode.
Hold B / 2 on the Audikast for 5 seconds until it flashes red and blue.
Wait for the B / 2 indicator to become solid blue.

Headphone 2 keeps connecting to my phone

Turn Bluetooth OFF temporarily on the phone or other device that normally connects to those headphones.

Then put the headphones back into pairing mode and restart B / 2 pairing on the Audikast.

Both indicators are blue, but only one has sound

Test each pair of headphones separately with the Audikast first.

If one pair does not work when connected by itself, troubleshoot that headphone connection before trying dual-link again.

One headphone connects by itself but not in dual-link

Confirm that Headphone 1 stays connected while you add Headphone 2.

Make sure the second headphones are in true Bluetooth pairing mode before starting the B / 2 connection.

Still Stuck? Reset the Audikast

If the second headphones still cannot connect after repeating the pairing steps, clear the Audikast pairing history and pair the devices again from the beginning.

Using Two Sets of True Wireless Earbuds?

Dual-link works with Bluetooth headphones and earbuds, but some true wireless earbud combinations may be less stable than standard Bluetooth headphones. If you are having trouble, test each set separately first.
