Wearing method
1. Identify the left and right earbuds. Look
for L/R mark near the round hole in the
ear-fin, which is used to fix it on the
earphone. Then choose the size that best
fits each ear - S, M or L.
2. Place the assembled earbud with the
eartip in your ear canal and tuck the ear-fin
into the front ear fold facing up. Adjust the
eartips to a suitable angle until you have a
tight and snug fit.
3. Please try various supplied eartips and
ear-fins to find comfortable and better fit.

Using the correct size eartips and
ear-fins is critical for maximum external
noise isolation and a snug, secure fit. It
is also common to have different sized
ear canals so try the eartips and
ear-fins one at a time to find the best fit
for each side.

Safety Rules

headphones dry before charging.
Avoid exposing TREBLAB X2 to extreme temperatures (below 37°F /
3°C or above 112°F / 45°C). Extreme temperatures can cause
deformation of X2 components, reduce battery life and the lifespan of
your new earphones.

animals.

serious malfunction and increase the risk of electric shock.

• We recommend a full charge twice a month to ensure battery
integrity.
• Please do not leave the device (and charging dock) in hot or cold
places, such as in a closed car in summer or winter conditions
because this will reduce the capacity and lifetime of the battery.
