If you see the red diamond in the middle of the OfficeRunner cube you can't get rid of or you just can't get the headset to turn off, give this a shot!
- With the headset OFF the base, press and hold the on/off button on the headset for about 5-10 seconds
- The headset will flash red (and if you’re listening it’ll make a series of powering-down sounds)
- Wait about 10 seconds. All the battery lights on the base will shut off and you will get a red diamond (if red diamond is already there, then the battery lights should disappear)
- Place the Sennheiser microphone back on the charging base and leave it alone for about 15 seconds. It should re-pair. You’ll get your battery lights back and your red diamond will go out
Thinking about getting a new Bluetooth headset?
Many Sennheiser Bluetooth headset users have switched to the Leitner LH380!
