JBL PartyBox 310 Bluetooth Won't Connect

Required Items

  • Your JBL PartyBox 310
  • Your Smartphone or Bluetooth Device

Troubleshooting Steps

  1. Basic Checks: Ensure Bluetooth is enabled on your phone/device. Turn the PartyBox 310 off and then back on again.
  2. Enter Pairing Mode: Press the Bluetooth button on the PartyBox 310. It should make a sound and the light should start blinking to indicate it is discoverable.
  3. 'Forget' the Device: On your phone's Bluetooth menu, find the PartyBox 310 in your list of paired devices. Tap on it and select 'Forget Device' or 'Unpair'.
  4. Attempt Re-pairing: With the speaker in pairing mode (blinking light), scan for new devices on your phone. Select the PartyBox 310 when it appears and confirm the pairing.
  5. Hard Reset the Speaker: If it still won't connect, perform a factory reset. Press and hold the 'Play' and 'Volume +' buttons simultaneously for about 10 seconds until the speaker restarts. You will need to re-pair it after this.
  6. Check for Interference: Move other wireless devices (like Wi-Fi routers, microwaves, other Bluetooth speakers) away from your PartyBox, as they can interfere with the signal.
  7. Test with Another Device: Try to connect a different phone or tablet to the PartyBox 310. If the second device connects, the issue is likely with your original phone's settings.

Bluetooth FAQs

Why does my PartyBox 310 keep disconnecting from Bluetooth?

This is often caused by distance or interference. Make sure your phone is within 30 feet (10 meters) of the speaker and clear of obstacles like walls. Also, move other wireless devices away that could be causing signal interference.

Can I connect two phones to the PartyBox 310 at the same time?

The PartyBox 310 supports Multi-Point Connection, which allows you to connect up to two devices at once. However, if you are having trouble, try disconnecting one device completely to see if it stabilizes the connection.

How do I know if my PartyBox 310 is in pairing mode?

When you press the Bluetooth button, the backlight around the button will begin to flash or blink. This indicates that it is discoverable and ready to be paired with a new device.

Does a factory reset delete any of my settings?

Yes, a factory reset will erase all paired Bluetooth devices and reset any custom EQ settings you have made in the JBL PartyBox app. It is a great way to solve persistent software issues.
