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

Sudio A1 Pro features silicone ear tips with a built-in mesh net, protecting the earbuds from dirt, grime (and the notorious earwax), all while sitting comfortably in your ears. These ear tips can be removed from the earbuds and cleaned with water or a cotton swab. Avoid hot water though, as this can distort the size and shape of the ear tips.

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 (pins). While the A1 Pro earbuds and case are splash-proof, subjecting them to high moisture levels could lead to permanent water damage.  

Psst, the Sudio Care Kit is ideal for regular maintenance and includes all the tools you need to keep your Sudio earphones in shape!  

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.

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 A1 earbuds, not the charging case.

Charging case (no cable inserted)

• One light: 0-25% battery remaining
• Two lights: 26-50% battery remaining
• Three lights: 51-75% battery remaining
• Four lights: 79-100% battery remaining

Charging case (with cable inserted and charging)

• First light blinking: 0-25% battery charged
• Second light blinking: 26-50% battery charged
• Third light blinking: 51-75% battery charged
• Fourth light blinking: 76-99% battery charged
• Four lights shining: 100% 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 A1 earbuds and case are sweat- and splash-proof, subjecting them to high moisture levels could lead to permanent water damage.  

Psst, the Sudio Care Kit is ideal for regular maintenance and includes all the tools you need to keep your Sudio earphones in shape!  

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.

If N2 Pro starts behaving unexpectedly, or if you wish to remove the connection between N2 Pro and the connected device, you can perform a factory reset to restore your Sudio N2 Pro to its original settings. This will reset the connection between your paired devices, as well as the connection between the two earbuds.

1. Place the earbuds back into the charging case, keep the lid of the case open.
2. Press and hold the reset button on the bottom of the case for 5-7 seconds.
3. The factory reset is complete when the LED light on the front of the case starts flashing white slowly.
4. Close the lid and allow 3 minutes before using the earphones again.

When you hear 🔈 Ready to pair, find your Sudio product in the Bluetooth list of your device, proceed to pair them with your Bluetooth device.

N2 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 6 hours on one charge (4,5 hours while using ANC), with up to 30 hours in total before the case needs to be recharged.

Each battery takes approximately 60 minutes to fully charge. 

Charging methods

The N2 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 is one LED-light that indicates 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 N2 Pro earbuds, not the charging case.

Charging case (no cable inserted)

• White: 26-100% 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. 

Sudio N2 Pro features silicone ear tips with a built-in mesh net, protecting the earbuds from dirt, grime (and the notorious earwax), all while sitting comfortably in your ears. These ear tips can be removed from the earbuds and cleaned with water or a cotton swab. Avoid hot water though, as this can distort the size and shape of the ear tips.

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 N2 Pro earbuds and case are sweat- and splash-proof, subjecting them to high moisture levels could lead to permanent water damage.  

Psst, the Sudio Care Kit is ideal for regular maintenance and includes all the tools you need to keep your Sudio earphones in shape!  

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.

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 A2 earbuds and case are splash-proof, subjecting them to high moisture levels could lead to permanent water damage.  

Psst, the Sudio Care Kit is ideal for regular maintenance and includes all the tools you need to keep your Sudio earphones in shape!

While ANC is activated, the earbuds can be used for approximately 4 hours on one charge, with up to 20 hours in total before the case needs to be recharged.

Each battery takes approximately 60 minutes to fully charge. Sudio Ett also supports quick charging, 15 minutes of charging gives 1 hour of playtime.

Charging methods

The Ett case can be charged with a USB Type-C cable but wireless charging is also supported. We recommend using the Sudio cable included in the package, however, other third-party USB Type-C cables may be compatible too.

Our product Sudio Ladd+ is compatible with Ett for wireless charging.

Battery level indicators

There are four LED lights on the front of the charging case.

The LED lights on the charging case indicate the remaining battery level of the charging case. The LED lights will be on when you take out the earbuds or put them back into the charging case.

• 75% - 100%: All four lights are on
• 50% - 75% battery level: Three white lights are on
• 25% - 50% battery level: Two lights are on
• 0% - 25% battery level: One light is on

Charging the earphones in the charging case

Put the earbuds inside the case in order to charge their individual batteries.

• When the left earbud is placed inside the case, the left-most LED light on the case will light up for a few seconds, indicating that the left earbud is connected to the case and charging successfully.
• When the right earbud is placed inside the case, the right-most LED light on the case will light up for a few seconds, indicating that the right earbud is connected to the case and charging successfully.
• If any or both of the earbuds are fully charged when they are placed inside the case, the LED lights on the case remain turned off. 

You can also check the remaining battery of the Ett earbuds on your mobile device.
For iOS devices, you are able to see the battery status on the home screen widget. If you do not have the widget, you can edit home screen settings to add it.
For Android devices, you are able to see the battery icon on the screen, there is also a variety of third-party Android app for reading battery levels on connected devices.

If Sudio Ett is not charging properly

In some cases, the charging pins inside the case scratch the receiving pole on the earphone, leaving residue that could potentially break the connection. Gently wipe the charging pin and receiving pole with a dry cloth or a swab and try charging the earphones again. The Sudio Care Kit is ideal for this, as it comes with all tools necessary to keep your Ett in tip-top condition!

If the earphones lose battery faster than usual, follow the instructions below:

1. Take out both earphones from the charging case and charge the case with the included cable separately until full.
2. Make sure the cable is fully inserted into the case and that there is no dust or dirt blocking the port. Note that inserting the cable forcefully can cause permanent damage to the cable and/or case.
3. Use the charging cable included in the product packaging and check that the cable is working correctly.
4. Try to get power from a different source i.e. laptop charging port or from a wall outlet.
5. If you have other Type C USB-cables, consider trying these and see if there is any difference.

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 the earbuds and inside the case, avoiding damage to the charging connectors (copper pins). Avoid using alcohol or chemicals, as this can damage the rubber coating on the earbuds and case. In some cases, being exposed to strong sunshine or high heat might alter the form of the silicon material.

Psst, the Sudio Care Kit is ideal for regular maintenance and includes all the tools you need to keep your Sudio earphones in shape!  

Light-colored earphones always need to be treated with a bit of extra care.

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.

Passive noise isolation is when devices are made to naturally block outside noise instead of actively doing it with noise cancelling technology. When headphones are designed to the exact shape of your ears, they prevent outside ambient noise from entering your ears. Whether you are walking down a busy street or if you are in a busy store you can still listen to music at a lower volume level because you don’t have to counteract the sounds of your environment.

Klar features two audio modes that let you decide what you want to hear - and what you don't want to hear. These two modes are called Active Noise Cancellation (ANC), and Normal (Off) mode.

The Active Noise Cancellation (ANC) mode in Klar reduces outside noise which allows you to fully immerse yourself in your own world.

How to switch between the modes

The earbuds are in Normal (Off) mode by default, where background noise is neither reduced nor amplified. By pressing the “ANC” marked button the green light will indicate that ANC is on. Press on the button again to turn ANC off.

How does Active Noise Cancellation (ANC) work?

The mechanics behind Active Noise Cancellation is in its name. The built-in microphones on Klar listen to the noise outside and inside the headphones while using the speaker to emit the same noise - but inverted - which reduces the outside noise nearly entirely. Klar uses Hybrid ANC technology, which is a combination of Feed Forward and Feedback ANC technology.
