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.
A:
From the Led Light to tell (Much easier)

Q:How to charge the Bluetooth headphones and
charging box?
A:There has 3 ways to charge the bluetooth headphones
and charging case.
1.Slide the switch to "on", let usb connect charging port
on the one side, on the other side connect charger with
USB ports or a USB output of a PC. At this time, it is the
charging box that is being charged. (If the charging case
is being charged, the led will flash green light nonstop; If
the charging case is full charged, the led will be green
light all the time.)

2. Slide the switch to "on", let usb connect charging port
on the one side, on the other side connect charger with
USB ports or a USB output of a PC. Put the Bluetooth
headphones on the charging box. At this time, It will
charge the Bluetooth headphones and charging box at
the same time. (If the earbuds are being charged, its led
light will be red; if the earbuds are charged well, its led
light will be blue. If the charging case is being charged,
the led will flash green light nonstop; If the charging case
is full charged, the led will be green light all the time.)

3.Slide the switch to "on", put the Bluetooth
headphones on the charging box. At this time, the
charging box is a power bank. If the charging box is full
charged, it can charge the earbuds for 3-4 times. After
you charge the earbuds well, then slide the switch to
"off", let it prepare the next time charging. (If the
earbuds are being charged, its led light will be red; if the
earbuds are charged well, its led light will be blue. If the
charging case is being charged, the led will flash green
light nonstop; If the charging case is full charged, the led
will be green light all the time.)

Q:Need I remove the ear hooks when charge the
earbuds on the charging box?
A:
Yep, you need, friend. If you don't remove the ear hooks,
the earbud charging contact point will not touch the
magnet point completely, it will not charge. And the ear
hooks main function is to prevent the earbuds from
falling. Because different customers have different ear
constructions, in order to overcome this point, so we
equip 3 different ear tips and the ear hooks. Hope our
customers can understand. (From the attached
comparison photos, it is easy for you to find the answer.)

Q:Whether can one earbud be connected to 2 mobile
phones?
A:Yes, when you try single mode, you can use one earbud
to connect to 2 mobile phones at the same time.
Please do it as following steps: 1.First time use. 2.Take out
one earbud, hold down earbud about 5-7seconds until its
LED flashes red and blue light nonstop. (make sure only
trun on one earbud) 3.Open the bluetooth of your 2
mobile phones, search and click the model "TWS-k2" to
pair and connect. If first mobile phone get connected, the
earbud will have voice prompt "connected"; if the other
mobile phone connects, earbud will have the other voice
prompt "the second device is connected".
Q:Why there has a switch on the charging box?
A:Because our charging box itself is a power bank, when
you use the usb to charge the charging box, if the
charging box is fully charged, it can charge the earbuds
separately for 3-4 times without usb cable. And when you
charge the earbuds, just need to slide the switch to "on",
if the earbuds are fully charged, slide the switch to "off",
let it prepare the next time charging. Every time it will
take 1-2 hours to charge the earbuds. So the power bank
feature can let customers use longer time.

Q:Why my earbuds battery not last long?
A:When you receive this package and use the earbuds at
the first time, the working time may not be very long,
because we test them before sending them out, that costs
some battery. Please don't worry. Charge them and they
will work as expected.
And our charging case itself can work as a power bank
when it is charged fully. It can charge the earbuds for 3-4
times. It will take 1-2 hours to charge the earbuds every
time. Usually Our earbuds working time is one for 3-4
hours, and a set for 2-3 hours. So if you want our
bluetooth headphones to work for 8 hours, please charge
the charging case well, this will solve your problem.
Q:Can I just use one headphone while the other one is
being charged?
A:Of course yes, friend. Our bluetooth headphones not
only can work together, but also can be used separately,
you can use one, and your friend use other one, this
won't make any influence. The key point is to keep one
headphone being turn off when you are pairing and
connecting the other one with your phone, doing this is to
prevent them from paring with each other. Once they get
paired well firstly, they will not work separately.

Q:Why one of my earbud can't be charged?
A:Because the earbuds are connected with charging box
by the magnet point and charging contact point. If one
earbud can't be charged, it maybe this earbud placed
incorrectly, please press the earbud firstly, let them touch
with each other completely.
Aside the above way, it is possible the earbuds or the
charging box battery has some problem. Please try the
following steps:
1.Make sure the charging case is fully charged.
2.Try to charge the charging box and earbuds at the same
time. Slide the switch to "ON", let USB connect to
charging port on the one side, on the other side connect
to charger with USB ports or a USB output of a PC. Put the
bluetooth headphones on the charging box.
3.Try to wipe the charging contact point and magnet point
with alcohol cloth. Then place the earbud on the charging
case. Press the earbud, let the earbud touch the charging
contact point completely .
You can also try to exchange the earbuds. To find whether
it is earbud problem or the charging case problem. If
these steps can't help you, contact us, we will send you a
new one as a compensation.

Q:Why my earbuds can't fit my ear? It is easy to fall out.
A:Sorry about this, because different customers have
different ear constructions, some customers fit well, some
customers don't. In order to overcome this point, so we
equip 3 different ear tips and the ear hooks. These
equipment will prevent the earbuds from falling. And
about the way to wear the ear hook, please try the photo
model wearing manner. If wear opposite, it is easy to fall.
Q:Can the twins Bluetooth headphones skip to the next
song or the last song?
A:Bluetooth headphones can only skip to the next song, it
can't skip to the last song. And the precondition is you
pair the twins bluetooth headphones successfully. When
the phone plays the song, click the right channel earbud,
then it will skip to the next song .

Q:Does the Bluetooth headphones have the volume
control?
A:Very sorry that our bluetooth headphones can't adjust
the volume by itself, you have to control the volume by
your phone. Because our bluetooth headphone only has
one multi-function key, it includes turn on/turn off/switch
language/answer call/end call/reject call/redial the last
number call/activate voice dialing/play or pause a
song/play the next song. It will be complicated if add
other functions. Hope you can understand.
Q:When talking on the phone, can I hear the voice in
both ear pieces?
A:When talking on the phone, you can only hear the voice
in the left channel. This safety feature allows you to hear
the traffic while driving.
Q:Is it sweat proof and water resistant?
A: Our bluetooth headphones' INGRESS PROTECTION is
IPX3, it is sweat proof, but not let the headphones
immerse into water completely. As for the electronics, we
would better not let them touch water, so we can use
them longer.

Q:Why the Bluetooth headphones work well indoor, but
work a little bad in the crowd?
A:Because the bluetooth headphones are influenced by
the signal. And the right channel earbuds signal is
connected by the left channel.
About the connection problem, it is related with using
environment. If the bluetooth is in the same frequency of
2.4 Hz , it will be influenced a lot. In our life, there has
many wireless devices in this section, will cause a
disturbance, resulting in poor signal. If there has a little
static, it is normal, there has many related factors; if there
has many times static, don't worry about it, contact us,
we will help you solve it .
Q:I listen to music firstly, then calling inserted, why the
voice is a little low at first, after a while, it becomes
normal. And why I use my phone to connect the
headphones being not well, but my friend is good ?
A:When come out this problem, please try to disconnect
and reconnect it, then the problem will be solved.
Because listening to music and calling are different
modules. A new module inserts into a different module, it
needs time to suit. And the signal is related to the using
environment, phone signal etc. Different time, different
people to use maybe different.

Q:How long does the bluetooth headphones last after
charging?
A:If a set is used at the same time for 2-3 hours, one is
used separately for 3-4 hours.
And the actually using time changes with the song types.
If for the soft music, it will play longer time; if for the
strong music, it will play shorter time.
Q:What is the meaning of the earbuds led
light(red/blue),the charging case green light?
A:When you charge the earbuds, if the earbud led light is
red, it shows it is being charged; If the earbud led light is
blue, it shows it has been charged well.
When you charge the charging box, if led light flashes
green nonstop; it shows it is being charged; if led light is
green all the time, it shows it has been charged well.
Q:Will the earbud fall from the charging box?
A:You don't need to worry about this problem, because
the earbuds and charging box are connected by the
magnet, even you turn over the charging box, it will not
fall off.
