Problem RemedyCause

Please try performing the pairing operation again after

Receives interference

from external factor,

and an impact

on the connection

status results

Bluetooth communicates using the 2.4GHz band.

This band is used by other wireless standards such

as Wi-Fi, etc., and so there is a possibility of

receiving interference. Moreover, this 2.4GHz band

does not penetrate liquids. There is impact from

humidity and rain, and the human body also

contains liquid, so there are individual differences in

connectivity. Furthermore, it depends on the

specifications of smart phones and other devices.

For that reason, switching OFF unused Wi-Fi/

Bluetooth settings on surrounding devices, etc. is a

countermeasure. While outside, there is a possibility

that moving a smartphone from inside a bag to a

breast pocket, etc. or otherwise reducing the

distance between devices may improve the

connection status.

Earphones are not

Earphones

In some cases, performing a reset operation may fix

Based on the design

specification, one side

is the parent and the

other side is the child,

so the burden between

left and right is

different

Under the specification for Bluetooth earphones,

communication generally takes place with one side

as the parent and the other as the child.

As such, the child only communicates with the

parent, but the parent communicates with the

smartphone or other device and communicates with

the child as well, and so there is a difference in the

level of burden borne by the left and right earphone.

As a result, a difference in the battery consumption

between the left and right may occur.

In case you are using the USB port on a PC, etc.,

there are cases in which the output is low and it may

take more time to charge than the publicly listed value.

As such, please use a 5V/1A USB adapter when

charging this product.
