The touch control is your remote control with which you for instance play music and answer calls without having to take your device out of your pocket or bag. The touch control is located on the earbuds.

Put the earbuds in the charging case and close the cap. Make sure that the charging case has battery life.

Plug the USB-C charging cable with the USB-C port on the charging case and plug the other end of the cable into a power source. Charging case and earbuds can be charged simultaneously.

Charging case battery status: A flashing blue light means that the earbuds are being charged. Each light on the charging case equals 25% battery life of the charging case. When each 25% is reached, the corresponding light becomes stable, and the next starts flashing. When charged to 100%, all lights turn off.

Earbuds battery status: How much battery life there is in the earbuds can be seen on devices like a smartphone. Check the top bar of your phone for a battery icon that appears when you connect your earbuds with it.

Two earbuds charging: The first and fourth charging case lights flash for about 5 seconds.

Only left earbud charging: The first charging case light flashes for about 5 seconds.

Only right earbud charging: The fourth charging case light flashes for about 5 seconds.

2. Create a new Bluetooth connection between the earbuds and the earbuds and your device by placing the earbuds in the charging case and close the cap. Then, open the cap and pick out the earbuds again.

You don’t do anything to reset your earbuds as they do that automatically when you open the charging case cap. Make sure though that when you open the cap, wait 1,5-2 seconds before you take the earbuds out of the case.

No they can’t. One device at a time only.

Yes you can.

Go to the Bluetooth settings on your device and look for a text or graphic that reads "disconnect pairing" or similar. Tap on that text/graphic to unpair.

• Make sure the earbuds are turned on.

• Make sure Bluetooth is turned on on your device.• Make sure that the earbuds aren’t connected to another device.

• Make sure the earbuds have battery life.

From the Bluetooth SIG website: "Interference is one of the biggest challenges for any wireless technology in providing reliable data communication. Since wireless technologies like Bluetooth®, Wi-Fi, and 802.15.4 devices share a transmission medium, it’s possible for a data packet that is being transmitted to be corrupted or lost if it collides with another packet being transmitted at the exact same time and on the same frequency channel."

This means that your earbuds can without apparent reason disconnect from your device. If this happens, and if your earbuds and device doesn't reconnect automatically, establish a new Bluetooth connection between the earbuds and your device by placing the earbuds in the charging case and close the cap. Then, open the cap and pick out the earbuds again.

Please remember that when the 10 meter Bluetooth range is measured, it's measured between two points without any objects in the way blocking the signal. This means that even though you have your device in your back pocket, the connection might not be 100 percent. If you experience a bad connection, please make sure that as little objects as possible are in the way between your earbuds and your device, for example clothes and accessories in your bag.

They are not. The shrieking sound appears when you’ve entered transparency mode before putting the earbuds back into the charging case. The sound will stop when you close the charging case cap and everything is as it should.

Why does the sound appear? Transparency mode activates microphones to listen to what's around you. This function is handy when you for instance are out walking amongst traffic. Because the microphones are activated and because the air in the earbud chamber are pushed into these microphones, you get acoustic feedback (the shrieking sound). You don’t have to do it, but if you want to avoid the sound, exit transparency mode before you put the earbuds back into the charging case.
