The volume level when streaming to any wireless device on some Android phones is, by default, very low so we boost it when streaming audio to your Here Buds. This may lead to you hearing some white noise, especially in your left ear.
There is a workaround for this issue:
1. With the buds already paired to the app, go to Bluetooth settings on your phone and tap the gear icon next to Here One and then tap ‘Unpair’
2. Open the Here One app
3. Open the main menu in the app, go to Settings, My Buds and tap on the (i) next to your pair of buds
4. Tap ‘Pair With Second Device (Beta)’
5. Go back into Bluetooth settings on your phone and select Here One under ‘Available Devices’
Your buds should now be reconnected to the app and for audio streaming without the noise in your left ear.
