Battery life figures on wireless headsets often come with a catch buried in the fine print. The AULA A500 is upfront about its: about 100 hours with noise cancelling off, and about 60 hours with it on. Both are long, but the gap between them is worth understanding if you plan to use ANC every day. Here is how the A500 battery life works out in real terms.
Quick Answer
The AULA A500's 1000mAh battery lasts about 100 hours with ANC off and about 60 hours with noise cancelling on, according to AULA. A full recharge over USB-C takes about 3 hours. At eight hours a day, 60 hours with ANC on covers more than a week of use before it needs a charge. The A500 costs R639 at Evetech.
🔋 Why ANC cuts the runtime
Active noise cancelling is not passive. The headset is constantly listening to outside sound and generating an opposing signal to cancel it. That processing runs the whole time ANC is on, and it draws power on top of playing your audio.
So the gap between the two figures is the cost of that processing. Switching ANC off removes it, which is why the rating rises from about 60 to about 100 hours.
📅 Putting the hours into days
Here is how the ratings work out at different daily usage levels:
- Eight hours a day, ANC on: about 60 hours, so roughly seven and a half days.
- Eight hours a day, ANC off: about 100 hours, so roughly 12 days.
- Four hours a day, ANC on: around two weeks.
- Four hours a day, ANC off: more than three weeks.
These are based on AULA's rating. Real results depend on volume, connection type and how you use the modes.
⚡ Charging
A full recharge takes about 3 hours over USB-C. The box includes a USB charging cable, so you have what you need from day one. Because the battery lasts so long, a good habit is to top it up once a week rather than waiting for it to run flat.
The battery is 1000mAh, a figure AULA lists alongside the runtime ratings.
✈️ Long trips and the 3.5mm cable
For long journeys, the A500 has another option. It includes an audio cable that plugs into a 3.5mm jack, so you can listen through a wired connection as well as wirelessly over Bluetooth 5.4 or the 2.4GHz receiver. That gives you a way to keep listening on devices that have a headphone jack.
Stretching the battery
- Use ANC only when you need it. Its dedicated key moves between transparency, cancelling and neither.
- Turn the volume down a little. Lower volume generally helps any wireless headset last longer.
- Switch it off when not in use. A headset left on and idle still uses power.
