We have 2 recommendations to remove static, background noise.
1. Make sure that the volume on your mobile phone or other device is set to maximum volume for best sound quality.
2. Some customers have reported that be sliding the power button to the left position on the Duo reduces background noise. This does not do any harm to the battery on the Duo as it is in charging mode when it is on the dock no matter the power button’s position.
If the problem continues, please contact our help desk by using the form at the bottom of this page.
