The earbuds will likely have some existing battery charge, however it is recommended to fully charge N3 Pro before using it for the first time.  

Turning N3 Pro on or off

N3 Pro powers up as soon as the earbuds are removed from the charging case, as indicated by the LED lights on the earbuds and the audio feedback 🔈 Power On.

Similarly, N3 Pro is turned off when placing the earbuds back into the case. 

You can also use the touch controls to power the earbuds on or off. Do this by holding the touch control for 7 seconds on either earbud.

There are three batteries in total on N3 Pro; one in the charging case and one in each earbud.

The N3 Pro earbuds charge their batteries automatically when placed inside the charging case, this is indicated by the LED lights on the earbuds. Make sure to first remove the protective film which is covering the charging connectors.

The N3 Pro case is charged with a Type-C USB-cable. When the case is charging, you will see a light on the front of the charging case. It is recommended to use the Sudio Type-C USB-cable that's included in the package, but the charging case may be compatible with third-party Type-C USB-cables as well.

If N3 Pro starts behaving unexpectedly, or if you wish to remove the connection between N3 Pro and the connected device, you can perform a factory reset to restore your Sudio N3 Pro to its original settings. This will reset the connection between your paired devices, as well as the connection between the two earbuds.

1. Take the earbuds out of the charging case.
2. Wait until the earbuds have gone through the voice feedback saying: 🔈 Ready to pair, find your Sudio product in the Bluetooth list of your device. Then proceed with pressing and holding both touch points on the earbuds for 6-8 seconds until you hear Power Off.
3. Release the touch button, and once again hold both touch points of the earbuds for 6-8 seconds until you hear 3 clicking sounds.
4. Leave the earbuds out of the case and close to one another for 20 seconds so they can resynchronize.
5. Place the earbuds back in the case and close the lid and allow 1 minute before using the earphones again.

N3 Pro powers up as soon as the earbuds are removed from the charging case, as indicated by the audio feedback 🔈 Power On. When pairing N3 Pro for the first time, you hear 🔈 On followed by 🔈 Ready to pair, find your Sudio product in the Bluetooth list of your device.

⚠️  Sudio N3 Pro is delivered with a protective film covering the charging connectors between the earbuds and charging case. The film needs to be removed in order for the earbuds to power on.

Pairing N3 Pro with a device

1. Remove the N3 Pro earbuds from the charging case and fit them inside your ears.
2. Go into the Bluetooth settings on your device. The N3 Pro earbud LED lights are flashing white while scanning for available devices. 
   • 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 N3 Pro in the Bluetooth list on your device.
4. When paired you will hear the audio feedback 🔈 Connected.

If N3 Pro has previously been paired with your preferred device, simply remove the earbuds from the charging case and they will automatically connect, so long as Bluetooth is activated on the device and N3 Pro has not been paired with a different device more recently. 

Device compatibility

N3 Pro uses Bluetooth version 5.4 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 take your N3 Pro and connected device outdoors to see if the interference clears.

N3 Pro can be up to a maximum of 10 meters (32 ft) from the paired device, but the connection may break if they are blocked by walls or similar objects. 

Pairing with multiple devices

N3 Pro can remember up to 10 devices and will pair automatically with the last used device.

It is possible to keep N3 Pro connected to several devices at the same time, such as a laptop and smartphone simultaneously, N3 Pro supports Multipoint connection.

You can quickly and easily switch between audio sources with your N3 Pro without having to manually disconnect and pair them to one device at a time. Multipoint helps to simplify the process of connecting, disconnecting, and reconnecting your N3 Pro every time you want to use them with a different device.

N3 Pro has a touch control button on each earbud that allows you to control certain features on your paired device.

Music/video playback

• Touch once on either earbud (left or right) to play or pause
• Touch twice on the left earbud to rewind

N3 Pro has three built-in batteries; one inside the charging case and one in each earbud. The battery inside the case is used to charge the earbuds, while the included Type-C USB-cable is used to charge the case.

Charging and play times

The earbuds can be used for approximately 5 hours on one charge, with up to 25 hours in total before the case needs to be recharged.

Each battery takes approximately 90 minutes to fully charge. 

Charging methods

The N3 Pro case can be charged with a Type-C USB-cable, wireless charging is not supported. We recommend using the Sudio cable included in the package, however, other third-party Type-C USB-cables may be compatible too.

Battery level indicators

There are four LED-lights that indicate the charging case's remaining level on the front of the case. 

The LED lights up when the earbuds connect and disconnect to the case and when there is less than 25% battery remaining.

When inserting the charging cable to the case, the current battery level is displayed for 5 seconds followed by a blinking light, indicating that the case is currently charging. 

In some cases, you can also read the battery level on your phone, such as iPhone or Android devices. The level shown is that of the N3 Pro earbuds, not the charging case.

Charging case (no cable inserted)

• White: 26-99% battery remaining
• Orange: 0-25% battery remaining

Charging case (with cable inserted and charging)

• White (fixed): 100% battery charged
• Orange/White blinking: 0-99% battery charged

Cleaning your earphones on a regular basis will ensure the best possible sound performance and prevent them from wearing out sooner than expected. 

Use only a slightly damp cloth when cleaning the earbuds and/or case. You can also use a fine brush or cotton swab to gently clean inside the case, avoiding damage to the charging connectors (copper pins). While the N3 Pro earbuds and case are sweat- and splash-proof, subjecting them to high moisture levels could lead to permanent water damage.  

Keep in mind that with time, some discoloration may eventually appear. This is most common if the earbuds or charging case continue to come in contact with dirty surfaces or materials over extended periods of time.

Yes, you can use one N3 Pro earbud on its own for both playback and calls. Both earbuds have the same components (speakers and microphones), which means that you can use either the left or right earbud at your leisure.

To ensure a stable connection, always keep the unused earbud inside the charging case. 

It’s always a good idea to charge both earbuds until full after having used them separately to maintain the same battery levels.

No, N3 Pro does not support wireless charging through Q1-technology or similar. Charge your N3 Pro case by inserting a Type-C USB-cable and connecting it to either a USB-port or to a wall socket via an adapter.

We recommend using the Sudio cable included in the product packaging, however other third-party Type-C USB-cables may be compatible too.
