Setup
1. Charging the Speaker
Before first use, fully charge the speaker. Connect the supplied USB-C cable to the charging port on the speaker and the other end to a USB power adapter (not included) or a computer's USB port. The charging indicator light will show the charging status.
A full charge provides up to 10 hours of playtime.
2. Powering On/Off
To power on the speaker, press and hold the power button (location not specified in data, assuming standard speaker design). Repeat to power off.
3. Bluetooth Pairing
The Stromberg Twin speaker can be used as a single unit or as two separate units for stereo sound. The pairing process differs slightly depending on your desired configuration.

Figure 2: The Stromberg Twin speakers support both Bluetooth and AUX connections.
Single Unit Pairing:
- Ensure the two speaker halves are magnetically connected to form a single unit.
- Power on the speaker. It will automatically enter Bluetooth pairing mode (indicated by a flashing LED, if present).
- On your mobile device (smartphone, tablet, laptop), enable Bluetooth and search for available devices.
- Select "Stromberg Twin" from the list of devices.
- Once connected, the speaker will indicate successful pairing (e.g., a solid LED light or an audible prompt).
True Wireless Stereo (TWS) Pairing (Two Separate Units):
To use the two speaker halves as independent left and right channels for stereo sound:
- Separate the two speaker halves.
- Power on both speaker halves. They will automatically attempt to connect to each other for TWS pairing.
- Once the two halves are connected to each other (indicated by a specific LED pattern or audible prompt), one unit will become the master and enter Bluetooth pairing mode.
- On your mobile device, enable Bluetooth and search for available devices.
- Select "Stromberg Twin" from the list. Only one "Stromberg Twin" entry should appear, representing the combined TWS system.
- After successful pairing, audio will play in stereo through both separated units.

2. Auxiliary (AUX) Input
For devices without Bluetooth, you can use the included 3.5mm AUX cable. Connect one end to the speaker's AUX input port and the other end to your audio source's headphone jack. The speaker will automatically switch to AUX mode when a cable is detected.
3. Using as a Single or Dual Speaker
The Stromberg Twin speaker's unique design allows for versatile audio experiences:
- Single Unit: Magnetically connect the two halves to form one compact speaker. This configuration provides powerful, unified sound.
- Dual Units (TWS): Separate the two halves to place them in different locations for a wider, true stereo soundstage. Ensure they are paired in TWS mode as described in the Setup section.

Maintenance
1. Cleaning
Wipe the speaker's exterior with a soft, dry, lint-free cloth. Do not use abrasive cleaners, alcohol, benzene, or other chemicals, as these may damage the surface or internal components.
2. Storage
When not in use for extended periods, store the speaker in a cool, dry place away from direct sunlight and extreme temperatures. It is recommended to charge the battery at least once every three months to maintain battery health.
3. Water Resistance
The Stromberg Twin speaker features IPX4 splash-proof protection, meaning it is resistant to splashing water from any direction. It is not designed to be submerged in water. Do not expose it to heavy rain or immerse it in liquids.
