If the buttons on your portable speaker are not working properly or are unresponsive while plugged into a power source, please try running the speaker on battery. If the buttons perform correctly while running on battery, this means your power supply is not providing enough current/amps. Be sure to use a power supply that has a rating equal to or greater than the amperage rating indicated in your product specs.Was this helpful? Thank you for your feedback!

If there are drop out or connection issues when using PartyBoost or Connect+, it could be one of three things.
1. Units are too far apart (move units closer together)
2. Interference from other 2.4gHz wireless units in the area.
3. Unit is no longer working as designed
Here are some steps to isolate the issue:
Try taking the units out of the house and test it outside with no interference to see if you still experience connectivity issues. If you still experience connectivity issues, please try steps below:
Whatever unit drops off, remove that from the chain. Test the rest of the speakers and keep doing it until you find the speaker that is causing the drop outs. If all speakers begin to drop off, please try a different order and repeat. Repeat this process with each unit being the “main speaker”.Make sure to turn off all WiFi/RF devices. (Router, laptop, baby monitor, Nest cams, IP cams, WiFi switches, WiFi outlets, WiFi lights, cordless phones, etc.)
You should be able to identify the issue/speaker by following these steps.

• Always have clear line of sight between your Bluetooth device (speaker, headphones etc.) and source device (Smartphone/tablet/PC etc). Be aware of obstacles in front of your devices.
• Try to shutdown other products that have Bluetooth, but are not being used. They are often the reason for interference even though they are not being used.
• Do not stand too close to your Wi-Fi router since a Wi-Fi signal is stronger and in many cases will "overlap" the connection.
• Be aware of walls around you. Concrete and brick walls will often interrupt the signal, as it cannot pass through such thick walls.
• Bluetooth signals cannot travel through water, which includes the human body. Make sure with wireless headphones to keep your source device and the receiver on the same side of your body.
• Open spaces such as parks can cause issues for your devices, as open air is "bad" for any Bluetooth signal if it cannot reflect from objects around you.Was this helpful? Thank you for your feedback! -
There can be differences in the internal hardware that also implies different firmwares. These products feature the same specifications and performance expectations. If the app does not inform you of any new updates, the firmware is current and the product is performing as designed.Was this helpful? Thank you for your feedback!
