Thanks for your feedback. We're always looking for ways to improve. For our JBL Tune 770NC, you can try troubleshooting the unit by resetting it. To reset: Turn the headphones on. Press and hold "Volume +" and "Volume -" for more than 5 seconds. The headphones will turn off and reboot to factory default. You may need to 'forget' the headphones in Bluetooth settings on your phone/tablet in order to pair them again. On the JBL Headphones app choose between Active Noise Cancelling (ANC) to shut out noise, Ambient Aware to hear environmental sounds or TalkThru to have quick chats with your headphones on. VoiceAware allows you to choose how much of your own voice you want to hear when on a call. If you need more help, please contact our customer support.
