I have a Sennheiser MM100 Bluetooth headphones that has stopped responding. It will not turn on/off and the LED light is blinking a continuous blue. How do I get it to function again?


Found this online. Hope it helps you out.

Switching the headset on
To switch the headset on:
Press and hold the Play/Pause button for 2 seconds.
An ascending confirmation beep is heard in the headset and the LED indicates the current operating mode. Flashing in blue indicates that the battery charge status is OK; flashing in red indicates a low
battery (see page 6).
The LED flashes several times every second:
The headset is paired to one or several Bluetooth devices and tries to connect to one of these devices.
The LED flashes slowly (once every second):
The headset is paired to one or several Bluetooth devices. However, there is no current connection because the
Bluetooth device is switched off or out of range.
The LED flashes once every 3 seconds:
The headset is paired to one or several Bluetooth devices. However, there is neither an audio transmission nor an active call.
The LED is glowing slowly every 4 seconds:
The headset is paired to one or several Bluetooth devices, a sound file is received via A2DP and played back or
paused.
The LED flashes once every second:
The headset is paired to one or several Bluetooth devices and there is currently an active call.
If you switch on the headset and keep the Play/Pause button pressed for 5 seconds, the headset will go into pairing mode (see ?Pairing the headset? on page 9).
The LED flashes alternatingly in red and blue for up to 60 seconds:
The headset is not yet paired to any Bluetooth device. Pair it as described under ?Pairing the headset? on page 9.

You will need to turn off your headset and then press and hold the power button until the LED starts to flash red/blue, red/blue, it will stay in this state for a few minutes.

The following procedure will re-establish the communication link between the Headphones and the Wireless adapter, this is called "pairing". Before you start please make sure both the headphones and the wireless adapter are fully charged and turned off.
Note: The headphones and the wireless adapter come pre-paired from the factory.
1. Press and hold the power button on the headphones. See Figure 1.

Figure 1

2. Continue to hold the button down until the LED starts flashing red/blue in an alternating pattern. Release the button when the LED starts flashing red/blue. See Figure 2.

Figure 2
3. Once the headphones LED is flashing red/blue, press and hold the power button on the wireless adapter. See Figure 3.

Figure 3
4. Hold down the button until the LED starts flashing red/blue in an alternating patter. The LED will blink blue, then turn off for a few seconds then blink red/blue. Release the button when the LED starts flashing red/blue. See Figure 4.

Figure 4
5. Once both the headphones LED and the adapter LED is blinking red/blue, press the volume up button once on the headphones. See Figure 5.
headphone-volumeup.jpg
Figure 5
Once the headphones is paired with the adapter, the LED on the headphones will blink blue once every two seconds. See Figure 6.
headphone-flash2.gif
Figure 6
When the adapter is paired the LED will be solid blue. See Figure 7.
receiversolid.jpg
Figure 7
The adapter may continue to blink red/blue for a few seconds even after the headphones LED starting blinking blue. This is normal; the adapter may take a few additional seconds before the LED turn solid blue.
Once the headphones and the adapter are paired, it is not necessary to pair them again even if the batteries on both units are completely drained.
Additional Note: Repeated pairing will not improve the sound quality or give the headphones and the adapter a cleaner connection.
