What to do when sound is only coming out from one earbud

If your earbuds say “pairing successful” but you can only hear sounds from one side, this indicates that the earbuds are no longer paired together. In order to pair them again, please put back both earphones in the charging case, wait for 5 to 10 seconds and lift both at the same time. If this does not work, please try the factory reset by following the instructions below.

Factory reset instructions:

  1. Turn off Bluetooth on your device.
  2. Put both earbuds in the charging case and make sure to close the case.
  3. Forget “Sudio Nio” on the Bluetooth list on your device. Sudio Nio should no longer be synced to your device. If you have connected Sudio Nio to multiple devices, forget them from all other devices as well.
  4. You can see the button on the bottom of the charging case. Press and hold the button for 3 seconds.
  5. Turn on Bluetooth on your device and select “Sudio Nio” in the Bluetooth list to pair it with your device.

Factory reset instructions:

    1. Turn off Bluetooth on your device.
    2. Put both earbuds in the charging case and make sure to close the case.

    5. Turn on Bluetooth on your device and select “Sudio Nio” in the Bluetooth list to pair it with your device.

How to manage multiple devices

Sudio Nio can remember up to eight paired devices, which means that you don't have to follow the pairing step every time you switch between devices. When Sudio Nio is turned on, it will automatically connect to the device most recently connected.

If you want to reconnect to one of your previously paired devices, please disconnect Sudio Nio first from the device you are currently using, and click "Sudio Nio" on the Bluetooth list of the next device you want to connect.

Sudio Nio supports multi-pairing, but you can only play audio from one device at a time. (Multi-point connection is not supported.)

How to charge Nio

When you want to charge your earbuds, simply put them back into the charging case and make sure to check that the LED lights of both earbuds and the charging case start blinking.
It takes 90 mins to fully charge the earbuds from 0% battery. However, 15 minutes of quick charge gives you 1 hour of play time.

It takes 150 minutes to charge the earbuds and the charging case from 0% battery. When both the earbuds and the charging case have no battery left, charge the charging case without the earbuds for 15 mins first. Then, put the earbuds back into the charging case to start charging them. This is to prevent Sudio Nio from rebooting in a loop while charging, at which point they will no longer function correctly.

How to check battery status on Nio

The LED lights on charging case and earbuds indicate the remaining battery level. The colour of LED lights change depending on how much battery is left.

0% - 25% battery level: Yellow light is on
26% - 100% battery level : White light is on

What to do if neither earbuds nor case are charging

When both the earbuds and the charging case have no battery left, you first need to charge the charging case alone to a certain level in order to prevent Sudio Nio from rebooting in a loop. If the earphones are rebooting in a loop, they will not longer function properly.

To charge the earphones correctly, please follow the steps below.

  1. Remove the earbuds from the charging case.

Water resistance rating (IPX4)

Sudio Nio is a device with a level 4 water protection rating, which means that the earbuds are water resistant. At this level, the earbuds can handle heavy rain, sweat, and the occasional accidental splash.


IPX is an official third party rating that is awarded by through a series of tests. Sudio Nio is also completely sweat-proof and can be used during exercise.


However, for an IPX 4 rating, we would like to communicate that there is no guarantee that the earbuds will remain full operational after activities like swimming or showering with them.


While the earbuds have an IPX4 protection, the charging case is not waterproof. If you touch the charging case with wet hands or put the earbuds into the case while they are not completely dry, the product might be damaged. Please always make sure that earbuds are not wet when you put them back in the charging case. Unfortunately, if the earphones are damaged in these cases, they will not be considered a manufacturing defect and will not be eligible for replacement through our warranty.

Adaptive dual-microphone technology

Adaptive dual-microphone technology filters out unwanted background noise while you're on a call.
Sudio Nio has two microphones on each side of the earbuds. In total, Nio offers four microphones with adaptive dual-microphone technology that adjusts the microphones according to ambient noise to deliver clear voice or sound.
