Bluetooth In-ear Noise Cancelling Earbuds - Black

With the touch keys of the noise-cancelling earphones you are able to perform the following actions

Tuning in music

Press the right or left side of the earbuds to perform various actions. Just press the earphones to pause songs, control the volume or select the next song.

Calling 

If you receive a call while wearing the earphones, you can answer, hang up or call back with just a few presses. There is no need to remove the earphones from your ears to accept incoming calls.

Noise cancelling filters out ambient noise so you can focus on the music, audiobook or podcast. Turn noise cancelling on and off with touch control. Ideal for working in a focused way, on the move and when travelling.

Noise cancellation works best in noisy environments (train/car/bus). Because of the low frequency, the noise cancelling works at its best. When the noise cancelling is used in an office or living room, it is difficult to notice the difference. The human ear can hear a frequency of 20Hz to 20KHz. The sound of human talking is approximately 100Hz to 8KHz. This frequency cannot be completely cut off by the noise cancelling system.

Remove the two earplugs from the charging box and the earplugs are automatically switched on. When the earplugs are switched on, an indication sound is heard with the text: "Power on". The indicator light of the earplugs then flashes red and blue alternately.

Once the two earbuds are connected, open the Bluetooth settings on your device and click "NC100" to connect. An indicator sound is heard saying "Connected" when the earbuds connect to the device. After the Bluetooth connection has been successfully established, the indicator light on the earbuds is switched off. Now they are ready for use.

After connecting to the device for the first time, the earbuds are automatically connected to the device when they are turned on. Earbuds automatically turn off if no Bluetooth connection is established after three minutes.

When the battery is almost empty, an indication sound sounds with the message "Please Charge". After 3 indications, the red LED flashes 3 times and an acoustic signal is heard that says "Power off". The earplugs are automatically switched off.

Charging the charging box: Connect the included micro USB charging cable to the charging box and to a power station. The white LED of the charging box flashes during charging and all three white LEDs light up when fully charged.

Charging earbuds: Place the earbuds in the charging box and they automatically switch to charging mode. The white LED of the earphones lights up while charging. The red light goes out when fully charged.
