*In order to maintain the sound quality of the device, when using the device and charging at the

off the device until the temperature returns to the ideal range.
*Do not use it at excessive volume for a long time, otherwise it may damage your hearing. In
addition, the laws of some countries/regions stipulate that in an environment that affects hearing
and has a sound volume of 86 decibels, you may not stay for more than 8 hours a day. Therefore,
it is recommended that if you want to use the headset for a long time, turn down the volume as
much as possible. Please be sure to maintain your hearing health.
*Audio Box has a built-in rechargeable lithium battery. Generally speaking, the service life of this
battery is usually related to usage habits. If you think the included rechargeable lithium battery is
exhausted (low battery), please try charging first. If the battery cannot be charged smoothly after
many attempts, the battery may be out of use. Do not disassemble and replace the battery by
yourself.
