Charging the headphones
- Open the micro-USB cover to access the micro-USB input.
- Connect the micro-USB plug of the charging cable to the micro-USB input of the headphones.
- Connect the USB plug to the USB port of your computer. If you are using an external power adapter, connect the USB plug to the power adapter or to the USB car charger adapter, and connect to the power source.

Pairing the headphones
CAUTION
The danger of malfunction!
The transmitted radio waves of mobile phones can impair the operation of sensitive and unprotected devices.
- Only make calls with the headphones in locations where Bluetooth wireless transmission is permitted.
The M2IEBTSWIn-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:
- Hands Free Profile (HFP)
- Audio/Video Remote Control Profile (AVRCP)
- 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.
To pair and connect the headphones to a PC or Mac, it is recommended to use a Sennheiser Bluetooth USB dongle, such as the BTD 800 USB.
