Water use: I can't hear well after Milo was in water

Although Milo is completely waterproof and has an IP67 rating, meaning it can be submerged in up to 1m (3 ft) of water for a half an hour without harm, Milo is not designed to operate under water, one reason being that water collects in the speaker cavity. It's normal for water to collect in the speaker cavity, but the speaker won’t work as well if the water remains.

You can clear the water out manually or use the Water Clearing mode (first added as a Preview Feature in version 8.0.0; Standard feature in version 9.0.0). 

Manual clearing

After Milo has been submerged:

    1. Remove from clip or armband.
    2. Hold Milo with the speaker grill facing down to clear water out of the speaker cavity.
    3. Give the device a good shake or two to ensure all water is removed.
    4. Reattach to clip (and wrist strap if it was removed).

Using Water Clearing Mode

To enable:

(version 8) In Milo Link, enable in Preview Features.

(version 9 and later) In Milo Link, enable in Advanced settings, or via the on-device menu: On the Milo, click the smile-shaped button to enter the on-device menu. Use volume keys to navigate the menu options. When you hear the Water Clearing option, click the side button to enable or disable.

To activate for use:

Press-and-hold the Milo button for at least 1 second, then let go.

A tone plays over several seconds, helping drain accumulated water from Milo’s speaker cavity and microphones.



To avoid water accumulating in the speaker, we also recommend mounting Milo pointy-end down in the clip to assist in draining any water.

Known limitations 

  • PTT is unavailable in this mode since holding the Milo button is used for water clearing.
  • Mic processing is tuned to keep typical water sporting noises out. As a result, you may need to speak louder when volume is turned up high, or set to Volume Boost. When not used around water, we recommend disabling the feature.
  • If not enabled and the speaker gets water logged, acoustic echo cancellation (AEC) may not trigger in all conditions, resulting in echo feedback.
