noise cancellation
 IPX-7 Waterproof
 Bluetooth Version 4.1 + EDR

Using the provided USB/micro USB cable, connect
the micro USB end of the charging cable to the
micro USB charging port and the standard USB end
to a PC USB port or USB charger.

WEARING THE TREBLAB EARPHONES
Using the correct size earbuds is critical for external
noise cancellation and securely staying in your ear.
Use the appropriate size expandable foam ear-tips
to help the earbuds stay in place. XR500 earbuds
have a wire that could be easily fixed around the
back of your head (neck) using a supplied cord
minder to ensure additional securing of the earbuds
and preventing their loss. It is also common to have
different sized ear canals so try the ear tips one at a
time to find the best fit for each side. Everyone has
individual anatomic features, and to find the most
comfortable fit, you might additionally buy special-
ized tips.
 To seat the ear tip firmly try gently pulling on the
outer rim of your ear to ease the tip into a comfort-
able position. You should notice a drop in ambient
noise when the tip is seated correctly. And when
you're listening to music, you'll notice more range,
especially bass.
