5. True Wireless Stereo (TWS) Pairing (Optional)
To achieve a stereo sound experience, you can pair two Coby Encore speakers together.
- Ensure both Coby Encore speakers are powered on and not connected to any other Bluetooth device.

For devices without Bluetooth, use the AUX input.
- Connect a 3.5mm audio cable (not included) from your audio device's headphone jack to the AUX Port on the back of the speaker.
- The speaker should automatically switch to AUX mode. If not, you may need to press a mode button (refer to control panel).
Operating Instructions
The Coby Encore speaker features integrated controls for convenient audio management.
Control Panel Functions
While the exact layout may vary, typical controls include:

Bluetooth Operation
Once paired with your device, audio will stream wirelessly to the speaker. You can control playback and volume either from your connected device or using the speaker's integrated controls.
AUX Input Operation
When connected via the AUX port, the speaker will play audio from the wired source. Volume can be adjusted on both the speaker and the connected device. Playback controls (play/pause, track skip) typically function only on the connected device when using AUX input.
Maintenance
Cleaning

- Avoid getting moisture into any openings.
Battery Care
- To prolong battery life, fully charge the speaker before its first use.
- Avoid exposing the speaker to extreme temperatures (hot or cold), as this can affect battery performance.
- If storing the speaker for an extended period, charge it to approximately 50% every few months.
