Note
1. If the product has not been used for more
than 2 weeks, it is recommended to charge
the product before use.
2. Only use certified chargers supplied by qualified
manufacturers.
3. Continuous use of the earbuds for a long time
is detrimental to one's hearing. Do not use
the earbuds at a high volume for any extended
period.
4. Using earbuds can reduce the perception of
external sounds. Do not use earbuds in
environments that may threaten safety. It is
recommended to only use a single earbud
when outdoors.
Due to the connection characteristics of the
Bluetooth signal, in dense environments with
2.4 GHz electromagnetic signal interferences,
there may be occasional disconnects or no
sound.
