Pairing the headphones

CAUTION Danger of malfunction!
The transmitted radio waves of mobile phones can impair the operation of sensitive and unprotected devices.
X Only make calls with the headphones in locations where
Bluetooth wireless transmission is permitted.
The M2IEBTSW In-Ear Wireless headphones comply with the Bluetooth 4.2 standard. In order that data can be transmitted wirelessly using Bluetooth technology, you have to pair your headphones with compatible Bluetooth devices that support the following profiles:
X Hands Free Profile (HFP) X Audio/Video Remote Control Profile (AVRCP) X Advanced Audio Distribution Profile (A2DP)
When you switch the headphones on for the first time, they automatically go to pairing mode. If the headphones have already been paired with a few devices, they automatically try to connect to the most-recently connected Bluetooth device when switched on. The headphones can save the connection profiles of up to eight Bluetooth devices or smartphones.
If you pair the headphones with a ninth Bluetooth device, the saved connection profile of the least used Bluetooth device will be overwritten. If you want to re-establish a connection with the overwritten Bluetooth device, you have to pair the headphones again.

Troubleshooting
Leaving the Bluetooth transmission range
Wireless calling and streaming are only possible in the Bluetooth transmission range of your smartphone. The transmission range largely depends on environmental conditions such as wall thickness, wall composition etc. With a free line of sight, the transmission range of most smartphones and Bluetooth devices is up to 10 meters.
If the headphones leave the Bluetooth transmission range of the smartphone, the sound quality deteriorates and you hear the voice prompt “lost connection”. At this point, the connection breaks down completely. You can re-establish the connection if you re-enter the Bluetooth transmission range and you hear the voice prompt ”connected”.
X To re-establish the connection, press the multifunction button.

Clearing previously paired devices

1. Set the headphones to pairing mode, see page 14. The LED flashes blue and red. The headphones are in pairing mode.
2. Press the Volume/track + button for 2 seconds. The LED flashes purple 3 times. The headphones are permanently disconnected from all devices and immediately go into pairing mode.
