• 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!
