[SOLVED] QFX Bluetooth Speaker Not Working

Is your QFX Wireless speaker’s Bluetooth is giving you problems? Are you looking for some quick solutions? We recommend trying these quick and easy solutions first before replacing the speaker.

QFX Speaker is Not Charged

One of the most common reasons for Bluetooth connection dropouts is your speaker battery not being charged enough. This issue becomes even more prominent when you are listening to some music on your Bluetooth connection and try to increase the volume. Since turning up the volume requires more battery power, your Bluetooth connection starts getting flaky if the speaker isn’t charged enough.

Solution: Make sure your speaker is fully charged. If you face a Bluetooth connection drop in the middle of a party, connect your charging cable immediately or toggle to the USB mode.

Your Device is Not in Range

Sometimes overlooked, the connected device not being in range is the reason for the QFX speaker Bluetooth not connecting problem.

When you connect your QFX speaker to your phone/tablet/laptop etc., via Bluetooth, ensure that the connected device is in the range. The Bluetooth range of the QFX speaker is 100 feet unobstructed. This range can change (be reduced significantly) if there are concrete walls or metal between your speaker and the device.

Solution: Bring the speaker closer to the phone.

Other Wireless Devices Are Interfering

If your QFX Bluetooth speaker is surrounded by multiple wireless devices like Wi-Fi routers, wireless keyboards/mice, smart TV’s, etc., there will be interference. In this case the Bluetooth connection will either drop or be unstable. In other words, it will cut in and out.

Solution: Change your speaker’s location or remove the other interfering devices from the vicinity. Please note that any wireless technology operating at 2.4 GHz including Microwave ovens and other Bluetooth devices can cause interference.

Your QFX Speaker Needs a Reset

Sometimes the Bluetooth connection starts dropping for no apparent reason. In that case, it’s a good odea to reset your speaker.

Solution: Reset the QFX speaker, hold the power and volume down buttons together for 6 seconds. Your speaker will be reset. Now turn it on and pair it with your device again.

Bluetooth needs to be repaired

If all the above solutions didn’t work for you, try the following:

Forget your QFX Bluetooth from your device by

  • Go to the paired devices list.
  • Turn off your QFX speaker and turn it on again.
  • Press the mode button slightly to select the Bluetooth mode.

Speaker Isn’t in Bluetooth Mode.

The QFX speaker also supports USB, AUX input, FM radio, and MicroSD card in addition to Bluetooth. It may be the case that your speaker isn’t in Bluetooth mode.

Check the display of your QFX speaker to see which mode it is in. If it is in Bluetooth mode, the display will have Bluetooth written on it. If not, press the mode button to switch through the modes and select the Bluetooth mode.

Solution: Ensure that the speaker is in BT mode

Speaker cannot Pair With Your Device

Whenever you reset your QFX speaker, all the paired device data gets deleted. In that case, your QFX speaker Bluetooth won’t connect with your device.

Another reason for QFX speaker Bluetooth not connecting might be the speaker pairing information being deleted from the device you are trying to connect. This happens when 7 devices are already paired, and you try to pair the new device. The paired device with the oldest connection time gets deleted in that case.

Maybe your QFX speaker was the oldest device, and it got deleted when you paired a new device.

Solution: Check the paired devices list on the Phone or Tablet you are trying to connect to your speaker.
