Tio - User guide - Connectivity & Pairing

Pairing Tio with a device


  1. Hold the middle button on your Tio for 5-8 seconds. The first blue flash means that your headphones are turned on. Keep pressing the button until you see the red flash - this means the headphones are ready to pair with your device.
  2. Go into the Bluetooth settings on your device. 
    • For iOS (iPhone), go to the Settings app and select Bluetooth.
    • For Android, go to the Settings app, then select Connections followed by Bluetooth.
    • For Windows 10, click on the Start button, select Settings followed by Devices, and then Bluetooth and other devices.
    • For macOS, go to the System Preferences app and select Bluetooth.
  3. Locate and select Sudio Tio in the Bluetooth list on your device.
  4. Once connected, the earphones will flash blue every 8 seconds or so.
  5. Your Sudio Tio is now paired with your device.
  6. To turn off your headphones, hold the middle button for 7 seconds. It will flash blue, this means the earphones are now turned off.

Device compatibility

Tio uses Bluetooth version 4.2 which is compatible with a wide range of Bluetooth devices. The paired device does not need to be the same version, but similar versions are more likely to maintain a strong connection. 

Signal interference

Some wireless devices may interfere with each others' signals, such as WiFi-routers, smartwatches, other Bluetooth devices, etc. If they operate within the same frequency, you may experience interference such as dropped sound and glitching. The easiest way to locate the cause of interference is by maintaining one connection between devices at the same time or taking your Tio and connected device outdoors to see if the interference clears.

Tio can be up to a maximum of 10 meters (49 ft) from the paired device, but the connection may break if they are blocked by walls or similar objects.

Tio - User guide - Battery levels and management

Tio has one built-in battery in the main body of the earphones.

Charging and play times

The earphones can be used for approximately 9 hours on one charge.

The battery takes approximately 120 minutes to fully charge. Tio also supports quick charge, 10 minutes of charging gives 1 hour of playtime.

Charging methods

The Tio can be charged with a Micro-USB cable included in the packaging. 

We recommend using the Sudio cable included in the package, however, other third-party Micro-USB cables may be compatible too.

Battery level indicators

When the battery level is low, the LED light indicator on the headphones will start flashing red.

Battery life status will be indicated on your smartphone for iOS and most Android devices. Since phone manufacturers have various Android devices that work differently, you can also download various battery apps on the Google Play Store.

Tio - FAQ - What to do if Tio is not charging

If the red light fails to shine when attached to your charger, then there is a chance there could be a battery issue within your earphones, your charging cord, or your charging port.

  • Make sure you are using the charging cable included with Tio. You can also try using a different micro USB cable if you have one accessible, however we cannot guarantee that all third-party micro USB cables are compatible.
  • Make sure the cable is fully inserted into the earphones and that there is no dust or dirt blocking the port.
  • Try to get power from a different source i.e. laptop USB port or from a wall outlet.

The battery meter on your phone reads in increments of 20%. So it will go from 100, 80, 60, etc.
