Sennheiser MB 660 General Reset
- Switch the Headset OFF. To do this, turn the earphones outward (so the headset is flat and can go back in its case) to turn it OFF. It will say “Power Off.”
- Press the Sound Effect Mode button for 4 seconds. This is the bottom button on the right side of the headset. Its location is shown in the first graphic at the bottom of the page, Section 2. (the inside of the headband will have R for right and L for left)
- NOTE: after holding the button down for 4 seconds it will not give us any light or say anything. To see if the reset worked we can try pairing the headset to the phone again

Clearing Previously Paired Devices

- Press the Sound Effect Mode button again for 4 seconds until you hear tones and the voice prompt saying “Pairing List Cleared.” The LED lights will flash white in sequence. The headset is now permanently disconnected from all devices and will automatically enter pairing mode. See the second graphic for information on Step 3 in the pictures below
