Wireless Pairing
Ensure the TREBLAB HD77 is fully charged and the AUX cable is not plugged in.
- Turn ON your speaker by pressing and holding the POWER button for 3 seconds. You will hear the sound cue and the LED will start flashing BLUE, indicating that the speaker is in pairing mode.
- Activate the Bluetooth mode on your device (smartphone, tablet, laptop).
- Select TREBLAB HD77 from the Bluetooth devices list. Keep it within 3 feet (1 meter) of the speaker while pairing.
- If necessary, enter passcode 0000.

Reconnecting and True Wireless Stereo (TWS)
Reconnecting
After initial pairing, the speaker will automatically connect to the previously paired device when turned ON again. If reconnection does not happen automatically, the speaker will look for other previously paired devices within the effective distance range. TREBLAB HD77 can remember up to 8 recently paired devices.
True Wireless Stereo (TWS) - Pairing Two Speakers
TWS technology allows you to use two speakers paired wirelessly to create a wireless dual-channel system, delivering a true stereo sound effect. One speaker (Master, left channel) is paired with a smart device, and the other (Slave, right channel) speaker is paired with the Master speaker.
- Select the Master speaker and pair it to the smart device following the WIRELESS PAIRING steps. Then turn this speaker OFF.
- Turn OFF the Bluetooth on the smart device.
- Place the Master and Slave speakers near each other (distance should not be over 3 feet / 1 meter).
- Turn ON both speakers.
- Double-click the POWER button on the Master speaker. The LED indicators will start flashing BLUE and GREEN, indicating pairing with the Slave speaker.
- Turn ON the Bluetooth on the smart device. The speakers will connect automatically.
- Once paired, the Master speaker's LED indicators will slowly flash BLUE.
To connect in TWS using the AUX cable, perform steps 3-6 above and plug the AUX cable into the Master speaker. The LEDs on both speakers should turn green.
To disable the TWS function and disconnect the Master and Slave speakers, press and hold the VOLUME + and VOLUME - buttons simultaneously on the Slave speaker for 5 seconds until the BLUE LED lights flash, indicating the connection is lost.
Audio Playback
- To pause and resume playback when connected wirelessly, press the PLAY button.
- To adjust the volume, press the VOLUME + or VOLUME - button while listening to music.
- To change the track on the HD77, press and hold the VOLUME + or VOLUME - button for 2 seconds.
3.5 MM Audio Cable Connection
You can connect TREBLAB HD77 to compatible devices using the supplied 3.5 mm audio cable.
Plug one end of the 3.5 mm audio cable into the 3.5 mm cable port on the side of the speaker (under the rubber cover). Plug the other end into the 3.5 mm jack on your device.
Turn the speaker ON. You will hear the sound cue and the LED light will turn GREEN. Now you can play music and audio.
NOTE: On-device control is not supported for NEXT, PREVIOUS, and PAUSE functions when using the 3.5 mm audio cable. Phone call management using the PLAY/PAUSE button is also not supported. You will need to make adjustments using your smart device.
Phone Calls
TREBLAB HD77 can be used to make and receive phone calls when connected wirelessly. Audio playback will be paused during calls.
- To answer/end a call: Press the PLAY/PAUSE button.
- To reject a call: Press and hold the PLAY/PAUSE button for 2 seconds.
- To redial: Press and hold the PLAY/PAUSE button for 3 seconds.
NOTE: For better call quality, face the microphone when you speak.
Troubleshooting
| Problem | Solution |
|---|---|
| Not powering on | Make sure the speaker is fully charged. Charge for 2 hours, if necessary. Press and hold the POWER button for 3 seconds. |
| Not pairing | Make sure the 3.5 mm audio cable is not plugged in. Ensure the speaker is not paired with any other device, as it can only pair with one device at a time. Press the VOLUME + and VOLUME - buttons simultaneously and hold for 3-5 seconds when not connected to the device. This will force the speaker to forget previously paired devices. Repeat the pairing steps. Alternatively, disconnect the device from your speaker and remove HD77 from your device's pairing list. Try to pair again. |
| Not finding a wireless driver on your laptop | Make sure your laptop supports wireless connections. If not, you may need an external wireless USB adapter compatible with your laptop. For further details, consult your laptop manufacturer. |
| Frequent disconnection and noise | Ensure the distance between your device and the speaker is less than 30 feet / 10 meters. Ensure nothing is blocking the signal between your device and the HD77. Check if the speaker is running out of power. |
Charging
One full battery charge provides up to 9 hours of playing time at maximum volume and up to 12 hours at medium volume. When the battery is running low, you will hear a sound signal.
TREBLAB HD77 can be used while charging in both Wireless Mode and 3.5 mm audio cable modes.
To charge the speaker, plug one end of the supplied cable into the Type-C charging port under the rubber cover on the side of the speaker. Plug the other end of the charging cable into a standard USB port. It takes up to 4 hours to fully charge.
If the speaker is turned OFF, the LED light will turn RED. If the speaker is turned ON and connected to the device, the PURPLE LED will light up. The RED light will turn GREEN or the PURPLE light will go BLUE when the speaker is charged.
Use a 5V DC, 0.5-2 A adaptor or charger. Using a lower power source will increase charging time. Maximize battery lifespan by charging through a computer's USB port.
Unplug HD77 from the charging cable and the cable from the power source when not in use. Even a fully charged battery will lose its charge over time if left unused.
It is recommended to fully charge the HD77 speaker at least twice a month to maintain sufficient battery life.
