If your goal is to get the most battery life out of your device, you may want to consider turning off noise-canceling features. Noise-canceling technology works by using microphones to pick up surrounding sound waves and then creating opposing waves to cancel them out. This process requires a fair amount of processing power, which can drain your battery more quickly. However, soundcore's ANC headphones can last up to 40 hours of non-stop playtime in wireless active noise cancellation mode, which is more than enough for any long flight, making it a great companion for anyone.
