Losei TWS-K2 Installation guide

Q:How to pair the twins bluetooth headphones? I can
only pair one of the earbuds with my phone.
A:We have 2 ways to pair the twins bluetooth
headphones.
From the Led Light:

Step 1
1.Hold down both of them until their Led lights flash red
and blue nonstop (The time is probably 5-7 seconds).
Led light changing state
Note: Please don't release the multi-function when you
see both of the earbuds led light flashing red.

Step 2
2.Don't do any other thing, just be patient to wait for
15-18 seconds.
If there has just one earbud flashing red and blue light
nonstop, this is the "left channel"; the other one flashes
blue light, that is the "right channel".
Led light changing state

Step 3
3.Open the bluetooth of your mobile phone and search,
click the model "TWS-K2" to pair. They will get
connected.
After both of the earbuds connect with your phone
successfully, both of them will flash blue light.
(Note: If you don't pair them successfully, please turn off
the twins earbuds, and repeat the above steps)

From the Voice Prompt:
Step 1
1.After you wear the 2 earbuds, hold down both of the 2
earbuds about 5-7 seconds, you will hear voice prompt
"Power On", and several beeps. Release the buttons
until you hear the first "beep" voice.
(Note: Please don't release the multi-function key even
if you hear the "Power on". The first "beep" voice is later
than "Power on" .)

Step 2
2.Please be patient to wait for 15-18 seconds without
doing other things. The twins earbuds connect with each
other, and there has voice prompt "connected" "left
channel" "right channel" in turn.
(only listen to this voice prompt in turn, the twins
bluetooth headphones pair successfully)

Step 3
3.Then open the bluetooth of your mobile phone and
search, click the model "TWS-K2" to pair. And there has
voice prompt "the second device is connected".
Please note: All the key is the first step, hold down both
of the Bluetooth headphones for 5-7 seconds. Please
don’t release the multi-function key even if you hear the
voice prompt "Power On" between the time range.
Because only up to this time range, the twins bluetooth
headphones enter into pairing status. If you release the
multi-function key once you hear the "power on", it just
shows the bluetooth headphones enter into turning on
status. They will not pair with each other.

Q:How to set the language of voice prompt? I switch
the language to Chinese by accident.
