On average, from a full charge, the A-01 headphones will last for approximately 30-35 hours with both Bluetooth and Noise Cancelling switched on. If you use Bluetooth only, it can last up to 40 hours, whereas using Noise Cancelling only (no Bluetooth or audio) can last for 60 hours.
You can use them as wired headphones via the auxiliary cable to conserve the battery by switching off Bluetooth if you don’t need to use it. The more features you use, the faster the battery will drain, but you can keep an eye on the charge level next to the headphone icon on your phone.
When your Audeara A-01 headphones need charging, they should make a beeping noise. This means it’s time to plug them in to charge using the micro USB charger that came with them. They can take 6 hours to charge fully from a dead battery, which can last through 500 charges.
You won’t be able to use the headphones while they’re charging, so always charge them up ahead of time if you know you’re going to need them to prevent disappointment.
If you tend to be forgetful about turning the headphones off and find yourself often draining the battery this way, you can set a standby timer in the Audeara app. The timer will make sure that the headphones turn off automatically after a period of inactivity.
