05 Bluetooth Connection

1. Turn on the speaker

   Press and hold the power button for 2 seconds to turn on the speaker with a prompt sound. The blue light flashes, indicating it is in pairing mode.

2. Connect it to your device

   Turn on the Bluetooth of your device and select 'Mifa_A90'. Once connected, it will beep and the blue light will stay on. The speaker will automatically connect to the last-connected device when its Bluetooth is turned on.

Other Instructions

To connect to another device, press and hold the Mode (M) button for 2 seconds to disconnect the currently paired device. The speaker will then enter pairing mode.

06 True Wireless Stereo Function

The Mifa A90 supports True Wireless Stereo (TWS) for an immersive audio experience with two speakers.

1. Set up the TWS system

   Turn on two speakers and ensure no device is connected to either. Short press one speaker's '-' and '+' buttons simultaneously. A beep sound indicates pairing is taking place. Another beep sound confirms pairing is complete.

2. Pair two TWS speakers with a Bluetooth device

   Select 'Mifa_A90' in your Bluetooth device's settings menu. A sound will indicate a successful connection, and the blue light will remain on.

3. Stop the TWS

   Short press either speaker's '-' and '+' buttons simultaneously to disconnect the TWS connection.

Tips for TWS

• For the first time setting up the TWS system, the speaker on which you press the '-' and '+' buttons will function as the main speaker and left channel. The other speaker will be the dependent speaker and right channel.
• The true wireless stereo function supports only two speakers.
• After the first connection, the main speaker and dependent speaker roles will persist in future connections. They will automatically connect to each other upon power-on.
• After TWS setup, the dependent speaker's blue light stays on, while the main speaker's blue light indicates your operation.
• Once the TWS system is successfully set up, you only need to operate either speaker, and the other will perform the same operation simultaneously.
