Yes, Noise-cancelling headphones require batteries for the most part. They work with a technology called Active Noise Cancellation (ANC). This feature picks up external sounds via small microphones. Instead, the headphones generate sound waves that are opposite to them and cancel out the noise. They will need power to do so — and that comes from a battery.
Rechargeable batteries power many of today’s models. You can charge them as you would a phone. A fully charged helmet can provide 20 to 30 hours of use. There are still some older or budget models that continue to employ replaceable batteries, but this practice is becoming less common.
When the battery is depleted, the ANC function will cease to function. However, you can continue to use most headphones for music listening — albeit without noise cancellation.
Buy noise-cancelling headphones with long battery life and fast charging capabilities. Some popular choices, such as the Bose QuietComfort 35 II and Sony WH-1000XM4, can last through long flights or a full workday.
