audio device via Bluetooth. TWS (True Wireless Stereo) enables
stereo playback without a cable connection.
NOTES:
• In order for the TWS connection to be established between
the two earphones, the left earphone1must not be already
connected to the audio device (or another Bluetooth device
nearby) beforehand.
• If you encounter problems establishing the connection, pro-
ceed as described in the section “No connection to the
audio device” on page 14.
• The connection to the audio device is established with the
right earphone6.
• Please note that the establishment of the connection may
vary slightly depending on the device and the software
used.
1. Remove the earphones1/6from the charging box12.
These are automatically switched on and connected to
each other via TWS. Then the LED4of the right earphone
starts flashing red/white while the connection to the audio
device is being established. The earphone now transmits
the identification. The LED of the left earphone flashes
white.
2. Place the left earphone1in your left ear, the right ear-
phone6 in your right ear.
3. If necessary, start the Bluetooth connection on the audio
device (e.g. smartphone, MP3 player). The audio device
should now receive the device identifier STWSK 3 A1.

4. Establish the connection to the earphones on the audio
device. If you are asked for a password, enter “0000”.
When the devices are connected, the LED4on the right
earphone flashes white and an acoustic signal is heard.
5. Start the playback of a music track on the audio device.
The sound is reproduced via the1/6earphones.
NOTES:
• If you want to connect the earphones to a computer, set the
sound input in the operating system if necessary to use the
microphones of the earphones for chat programmes, for
example.
• If the Bluetooth connection is interrupted, the right ear-
phone6tries to re-establish it automatically.
-TheLED4on the right earphone6flashes red/white
during the search.
- When the connection is restored, the LEDs 3 / 4 on both
earphones flash white. If necessary, the playback will
have to be re-started.
- Repeat the connection procedure described above if the
automatic Bluetooth connection fails.
7.3 No connection to the audio device
If a connection to an audio device cannot be established or one of
the earphones
1 / 6 remains silent, carry out the following steps:
1. Delete all STWSK 3 A1 entries in the device list on the
audio device and switch off the Bluetooth function on the
audio device.
2. Remove both earphones 1 / 6 from the charging box 12 .
Press and hold both multifunction buttons
2 / 5 for approx.
5 seconds each until an acoustic signal is heard.
3. For both earphones1/6, press the multifunction but-
tons2/5simultaneously for approx. 10 seconds. The
LEDs3/4flash several times. Now any stored connections

7.4 Disconnect/interrupt a Bluetooth connec-
tion
• If you place the earphones1/6in the charging box12 or
switch them off, the connection to the audio device is tem-
porarily interrupted.
• In order to permanently disconnect the Bluetooth system
from the audio device, delete all STWSK 3 A1 entries in
the device list on the player.
7.5 Using a single earphone
You can also use each earphone separately.
1. Take the desired earphone1/6out of the charging
box12 and leave the other one in the charging box in
order to prevent the two earphones from pairing.
2. Wait until the LED3or4of the earphone flashes red/
white. Place the earphone1or6in your ear.
3. Start the Bluetooth connection on the audio device (e.g.
smartphone, MP3 player). The audio device should now
receive the device identifier STWSK 3 A1.
4. Establish the connection to the earphone on the audio device.
5. Now start the playback of a music track on the audio
device. The sound is reproduced via the earphone1/6.
NOTES:
• If you use only one earphone1/6, some functions are not
available during operation. These can then only be con-
trolled via the audio device.
• If you want to use both earphones on different audio
devices, switch off the other earphone while pairing with
the audio device, as otherwise both earphones will pair
with each other again.
