Main unit/ Ear tips

Regarding ear tips

To make it easier to differentiate between the left and right, we have given the cores different colors; the core of one ear tip is gray, while the other is red. (1) By pulling the sleeve of the ear tip back slightly to check the color of the core, it is easy to distinguish between left and right, even in places with subdued lighting. Since the core colors of neighboring sizes are different (the gray cores alternate between dark and light gray; the red cores alternate between red and pink), it is also easy to distinguish between sizes.

The way you position the earphone in your ear affects the sound quality. We recommend trying different positions by moving the earphone around while playing music. This will allow you to find the position that generates your most preferred sound. Once you figure out your favorite position it will be easy to set that position each time. The shapes of a person’s right ear and left ear are usually different. Therefore, the best position for each ear is usually different as well.
When removing the earphone from your ears, always hold the main unit first and then remove. Pulling the cord could cause the wire to become disconnected.
Do not apply strong impacts to the earphones or put excess force on the cable. If the product fails or wires are broken due to abnormal use, the product warranty is invalidated.
Leaving the product in locations exposed to direct sunlight, high humidity, or a dusty environment could cause the product to fail.
If the product fails, do not attempt to disassemble.
The earphone jack is for stereo reproduction only. If the earphone is connected to a monaural output jack, sound may not come out of one side.
