E2 - User guide - Connectivity & Pairing

Sudio E2 enters pairing mode immediately when opening the lid on the charging case. When pairing E2 for the first time, you hear 🔈 On followed by 🔈 Ready to pair, find your Sudio product in the Bluetooth list of your device.

⚠️  Sudio E2 is delivered with a red 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 E2 with a device

  1. Remove the E2 earbuds from the charging case and fit them inside your ears.
  2. Go into the Bluetooth settings on your device. The E2 earbud LED lights are flashing white and orange 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 E2 in the Bluetooth list on your device.
  4. When paired you will hear the audio feedback 🔈 Connected.

If E2 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 E2 has not been paired with a different device more recently. 

Device compatibility

E2 uses Bluetooth version 5.2 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 take your E2 and connected device outdoors to see if the interference clears.

E2 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

E2 can remember up to 10 devices and will pair automatically with the last used device. In most cases, you can switch between devices by selecting Sudio E2 in the Bluetooth list which pairs it with that device instead. However, some devices require E2 to be disconnected from the previous device entirely before they can be paired. It’s not possible to keep E2 connected to several devices at the same time, such as a laptop and smartphone simultaneously.

A2 - User guide - Care and cleaning

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

Sudio A2 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.

mceclip0.png

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!  

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.

 Pairing Nio with a device

mceclip0.png

  1. Remove the Nio earbuds from the charging case and fit them inside your ears.
  2. Go into the Bluetooth settings on your device. The Nio earbud LED lights are flashing white and red 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 Nio in the Bluetooth list on your device.
  4. When paired you will hear the audio feedback 🔈 Pairing Successful.

If you would like to use only one of the earbuds, you can do so by just taking out the one you want to use from the charging case.

If Nio 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 Nio has not been paired with a different device more recently. 

Sudio Nio will automatically turn on when you lift out the earbuds of the charging case, and it will turn off when you put them back in the case. You can also turn them off by pressing the touch button for 6 seconds until you hear "power off”.
In order to turn them on, put them back in the charging case and simply take them out of the charging case.

Device compatibility

Nio uses Bluetooth version 5.0 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 Nio and connected device outdoors to see if the interference clears.

Nio 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

Nio can remember up to 8 paired devices, which means that you don't have to follow the pairing step every time you switch between devices. When 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" in the 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.)

⚠️  Sudio Nio 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 charge.

Charging and play times

The earbuds can be used for approximately 5.5 hours on one charge, with up to 20 hours in total before the case needs to be recharged.

Each battery takes approximately 90 minutes to fully charge. Also 15 minutes of charging gives 1 hour of playtime.

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.

Charging methods

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

Battery level indicators

There are three LED-lights that indicate the respective batteries' remaining level. The charging case’s indicating light is on the front of the case, below the Sudio logo. The earbuds' indicating lights are below the touch control buttons. The color of LED lights changes depending on how much battery is left.

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

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.

 

Ett - User guide - Care and cleaning

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.

Tolv - User guide - Connectivity & Pairing

Pairing Tolv with a device

mceclip0.png

  1. Remove the Tolv earbuds from the charging case and fit them inside your ears. If you want to use both, make sure to lift the second earbud within 15 seconds of lifting the first one.
  2. Go into the Bluetooth settings on your device. The Tolv earbud LED lights are flashing white and red 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 Tolv in the Bluetooth list on your device.
  4. When paired you will hear the audio feedback 🔈 Device Connected.

If you would like to use only one of the earbuds, you can do so by just taking out the one you want to use from the charging case. Then proceed with connecting the earbud to either "Sudio Tolv" (Right) or "Sudio Tolv-L" (Left).

If Tolv 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 Tolv has not been paired with a different device more recently. 

Device compatibility

Tolv uses Bluetooth version 5.0 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 Tolv and connected device outdoors to see if the interference clears.

Tolv can be up to a maximum of 15 meters (49 ft) from the paired device, but the connection may break if they are blocked by walls or similar objects. 

Pairing with multiple devices

Tolv can remember up to 8 paired devices, which means that you don't have to follow the pairing step every time you switch between devices. When Tolv 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 Tolv first from the device you are currently using, and click "Sudio Tolv" in the wireless connection list of the next device you want to connect. Tolv supports multi-pairing, but you can only play audio from one device at a time.

Tolv - User guide - Button controls

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

Some apps, however, may not be compatible with the button controls. In this case, you are only able to control playback and calls via the paired device.

Music/video playback

mceclip0.png

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

Incoming phone calls

mceclip1.png

  • Press once on either earbud (left or right) to accept a phone call
  • Press (hold) for three seconds on either earbud (left or right) to reject or end a phone call

Power

Tolv powers on and off automatically when the earbuds are taken out or put back inside the case. However, you can also control this without using the charging case.  

  • Press (hold) for five seconds on either earbud (left or right) to power on (single earbud)
  • Press (hold) for five seconds on either earbud to power off (single earbud). After 5 seconds the listening mode will change, followed by 🔈 Power Off.

Tolv - User guide - Factory reset

 

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

  1. Disconnect Sudio Tolv from all previously connected devices, most often by clicking on the "Forget" button.
  2. Turn off both earphones by pressing and holding both buttons for 6 seconds.
  3. Start the earphones again by pressing and holding both sides for 13 seconds, until the lights stop blinking.
  4. Put the earphones back in the case and wait for 3 minutes.
  5. The factory reset is complete.

Then you can start to pair them:

  1. Lift both earphones from the charging case at the same time (do not lift one by one, but both at the same time) and they will be in pairing mode.
  2. Select 'Sudio Tolv' in the Bluetooth list on your device.

After the factory reset, if you're seeing multiple Tolv devices in your Bluetooth list, such as "Sudio Tolv" and "Sudio Tolv-L", it could be caused by having pressed the buttons directly after taking them out of the charging case, or not taking both earbuds out at the same time.

Tolv pairs automatically when you take them out of the case, so avoid clicking on the buttons after you have performed the factory reset.

Tolv - User guide - Battery levels and management

Tolv 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 Micro-USB cable is used to charge the case.

⚠️  Sudio Tolv 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 charge.

Charging and play times

The earbuds can be used for approximately 7 hours on one charge, with up to 35 hours in total before the case needs to be recharged.

Each battery takes approximately 90 minutes to fully charge. Tolv also supports quick charging, 10 minutes of charging gives 1 hour of playtime.

Charging methods

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

Battery level indicators

There are two LED lights on the back of the charging case. The left LED light indicates the battery level of the case. The right LED light indicates the battery level of the earbuds.

Charging case (left LED light)

  • White (fixed): 70-100% battery remaining. The charging case can fully charge the earbuds 3 to 4 times.
  • White (blinking): 40-70% battery remaining. The charging case can fully charge the earbuds 1 to 2 times.
  • Red (fixed): 10-40% battery remaining. The charging case can fully charge the earbuds up to 1 time.
  • Red (blinking): 0-10% battery remaining. The charging case is running out of battery and needs to be charged with a cable.

Earbuds (right LED light)

  • The light is red while the earbuds are charging. It will turn off when the earbuds are fully charged.

 

Tolv - User guide - Care and cleaning

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.

Regent/Regent II - Features - Passive Noise Isolation

DsVoPWZc.jpeg

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 - Active Noise Cancellation (ANC)

CjLBUADw.jpeg

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.
