MultiPoint Pairing

How to setup the etyBLU2 for use with two Bluetooth devices at the same time (MultiPoint)
  • Multipoint is enabled by pressing the Silver MFB button and the Volume Down key at the same time and holding them down for at least one second. You'll hear a tone confirming that there has been a change.
  • Pair the etyBLU2 with the 1st phone. Then turn off the Bluetooth radio on that first phone.
  • Pair the etyBLU2 with the 2nd phone.
  • Turn the first phone's Bluetooth radio back on.
  • Turn the etyBLU2 off and back on. It should connect to both phones now. If it doesn't connect on one or both, try forcing the connection on the phone(s) that it isn't paired to.

Multipoint can be disabled by simultaneously pressing both the MFB and Volume Down key and holding them for less than a second.


The etyBLU2 headset comes with a rechargeable lithium polymer battery.
Charge the headset for at least one hour before first use.
Charging time from empty: 2-3 hours
80% charge: 1 hour

Charging with the USB connecter (included)

  • Plug the micro USB connector into the etyBLU2 headset as shown.
  • Plug USB end of the charging cable into a computer USB port.
  • The solid yellow LED will indicate that the headset is charging.
  • When charging is complete the yellow LED turns blue.


Important: Sound quality and noise isolation depend on a good eartip seal.
  • Carefully insert the earpiece while pulling up and out on the back of the ear.
  • Twist the earpiece while inserting until outside noise is blocked out.
  • Position the earpiece for best fit and comfort.
  • Bend the boom so the microphone is close to the mouth.

  • 3-flange eartip: Moistening eases insertion.
  • Foam eartip: Roll down or compress foam eartip before inserting. Hold the eartip in place for about 5 seconds while the foam expands to create a tight seal in the ear canal.
  • Glider eartip: Simply push into ear canal.


To avoid discomfort, remove the headset slowly with a twisting motion to gradually break the seal. Open jaw slightly to equalize pressure, because suction can occur when the eartip is removed.

    Cleaning and Replacing Eartips

    Over time eartips may lose their elasticity. For best performance and retention, replace 3-flange eartips every 3-6 months. Replace foam and glider eartips regularly.

    To clean the 3-flange eartips:

    • Remove the eartip from the headset.
    • Clean with water and mild soap.
    • Dry the eartip before placing it back on the headset.

    Changing the Filter

    The earpiece in the etyBLU2 headset has a special filter that smoothes the frequency response and prevents earwax from entering the earphone. The filter is located at the end of the earphone and is visible when the eartip is removed. Change the filter if loudness decreases or the sound quality declines.

    Note: Filters are not reusable.


    Note: Use the tool to remove the filter.
    1. Remove eartip. 2. Insert tool into the filter. 3. Remove filter and discard.


    Note: Do not use the tool to replace the filter.
    4. Insert a new filter and press
        gently against a hard surface
        to secure it in place.
