Klar has one built-in battery in the headphones.
Charging and play times
The headphones can be used for approximately 30 hours on one charge.
The battery takes approximately 120 minutes to fully charge. Klar also supports quick charge, 10 minutes of charging gives 1 hour of playtime.
Klar can be charged with a Micro-USB cable included in the packaging.
We recommend using the Sudio cable included in the package, however, other third-party Micro-USB cables may be compatible too.
Battery level indicators
When the battery level is extremely low, the LED light indicator on the headphones will start flashing red.
Battery life status will be indicated on your smartphone for iOS and most Android devices. Since phone manufacturers have various Android devices that work differently, you can also download various battery apps on the Google Play Store.
