Depending on how the MUZIK headphones are used and how much the touch panel is used, the battery life should last up to 20 hours with a full charge.
How do I charge my headphones?
Use the supplied micro-USB cable to connect the headphone to power source. The LED indicator will pulse red, then turn solid green when it’s fully charged. After charging is complete, disconnect the micro-USB cable.
The headphone will fully charge in 3 and a half hours. The battery will last up to 20 hours with active noise cancellation.
You also may charge them for 15 minutes for 3 hours usage if you have less time.
