FAQ - Operation
How can I adjust the volume of T40 earbuds?
- Power up the earbuds.
- Press the power button on the right earbud one time to turn the volume up, and press the power button on the left earbud one time to turn the volume down.
Does T40 support active noise cancellation?
No.
What’s the IP rating of T40?
T40 meets the IP5 rating, which protects it from water and sweat. If you suddenly drop it into the water, it will survive, as long as the water isn’t deeper than 1 meter, and if you take it out in less than 30 minutes. Please let it air dry if you dropped it into water.
How can I clean the earbuds?
- Clean the contact pins using a clean cloth or cotton swab dipped in alcohol-based disinfectants. For precise cleaning, put the cloth on the end of a toothpick.
- Pull off the eartips and clean the metal mesh with a dry cotton swab. Remove any debris from the metal mesh with a clean, dry, soft-bristled brush.
- Do not use sharp objects or abrasive materials to clean T40.
- Do not let water get inside T40 and if you used a watered swab to clean the mesh, let them air dry after cleaning.
How can I switch between normal mode and bass boost mode?
Press the power button on either right or left earbud for five times.
