Use as wired headphones

If your audio source is not Bluetooth enabled, or if the Audition Pro battery is low (LED blinking red), you can use a 3.5mm audio cable to stream music. Connect the supplied 3.5mm audio cable between your device and the 3.5mm audio socket on your Audition Pro.

NOTE : The buttons and microphone on your Audition Pro will not work when connected as wired headphones.

Charging

When the LED blinks red, you should recharge your headphones. Remove the Micro USB port protector and charge the headphones via the supplied Micro USB cable. It normally takes about 3 hours to fully charge the battery. The LED will stay red when charging and will turn off when charging is complete.

Charging requirement: You can plug our supplied Micro USB cable into a compatible USB charger (wall charger/travel charger/car charger etc.) with 5V /500mA-2A output or to a PC/Mac USB port. It is OK to use most mobile phone chargers on the market.

Clear pairing history

You may need to reset your Audition Pro if it’s not working as expected. In standby mode, press and hold both “V+” and MFB buttons for 5 seconds until the LED flashes blue and red together very quickly about 2 times and then the headset will turn off automatically. Now your Audition Pro has been restored to its default settings. After turning it on again, it will automatically enter pairing mode.
