First Use: Selecting Tips
A proper seal between the earpiece and your ear canal is required to achieve the best
sound quality with the MEElectronics M-Duo. Please follow the instructions in the manual
to make sure you get a proper seal. It may take several minutes to get the correct fit, but it
will result in better sound, comfort, and noise isolation in the long term.
Select and install the correct ear tips for your ears
This may require trying multiple sizes/types of ear tips. If you have larger ears, try the larger
tips first. if you have smaller ears, try the smaller tips first. Because ear canals may not be
symmetric, you may need to use different-sizes or types of ear tips in each ear. When
changing ear tips, make sure they are installed securely before putting the earpiece in your ear.
Standard Silicone Tips (small, medium, large):
The standard silicone ear tips come in three sizes to fit most ears.
With a shallower insertion than the double flange ear tips, they
provide a high level of comfort and good seal for most ears.
Many people report these tips work best for their ears, and they are
a good choice if you don’t feel comfortable with the deep insertion
the double-flange ear tips provide.
Double-Flange Tips:
Double-flange ear tips are designed to insert more deeply into the
ear canal than the single-flange ear tips, creating a tighter, more
secure seal. The double-flange ear tips fit a wide range of ears
comfortably.
