TWS mode
TWS mode (True Wireless Stereo) allows two compatible speakers to be paired wirelessly to create
true stereo audio with separate left and right channels. The speakers connect to each other
wirelessly: one acts as the primary device, connecting to your smartphone or playback device, while
the other functions as the secondary device, reproducing the second audio channel.
This setup produces spatial stereo sound, comparable to the listening experience of a traditional
stereo system.
This mode offers numerous advantages:
• Improved sound quality thanks to separate stereo channels
• Wireless connection – no audio cable required between the speakers
• Ideal for parties or larger rooms where a wider sound image is desired
Note: The TWS mode is generally only available in Bluetooth operation and cannot be used with
AUX or USB playback. In TWS mode, only the primary speaker (main device) can be used for
phone calls; the secondary speaker (secondary device) does not support call functionality.
Activate TWS mode:
1. Switch on both speakers.
2. Press buttons (1) and (3) on either speaker simultaneously for approximately one second in any
mode to activate TWS pairing mode.
3. The two speakers will automatically connect to each other.
4. Once the TWS connection is successfully established, your smartphone can discover and
connect to the primary speaker via Bluetooth.
Deactivating TWS mode:
To exit TWS mode, press buttons (1) and (3) on one of the speakers simultaneously for about one
second in any mode. This will disconnect the two devices.
