The projector has integrated speakers, but also supports audio output via Bluetooth to connect external speakers wirelessly. A connection to Bluetooth speakers is possible, but the external speaker is not always displayed as a separate audio source, which must be taken into account when pairing.

A physical audio output (headphone connection) is not explicitly mentioned on the MoGo 3 Pro, and according to the information available, the model does not have a separate headphone socket. External speakers are therefore best connected via Bluetooth.

To summarise: You can connect your speakers to the projector wirelessly via Bluetooth, there is no classic audio output for cable connections.
