The charging box and the buds contain an integrated rechargeable battery. Please make sure that this is fully charged before first use. It takes approx. 1.5 hours to charge the buds inside the charging box and it will start automatically once inserted into the box. It takes approx. 2 hours to charge the charging box. Simply connect one USB-C port of the supplied USB-C to USB-C cable to a suitable power source (5V-1A) and the other USB-C port to the charging box (USB-C In). The current charge status is displayed on the three-digit numerical display as a percentage. Simply open the lid of the charging box. The last digit will flash when the charging box is being charged. When the buds are being charged inside the charging box, you will be able to see a charging animation on both sides. The animation will stop as soon as the ear bud has charged fully.
Once the buds are fully charged, the battery will last for approx. 7 hours of music playback (depending on volume, Bluetooth connection and other factors). The charging box capacity will allow you to charge the buds approx. 2.5 times, resulting in a total playback time of approx. 25 hours without a power source. Please charge the charging box, including the buds, every 3 months when not in use to prevent deep discharges.
Bluetooth connection
The buds must be paired with the playback device the first time they are used. Bluetooth is activated in pairing mode as soon as the charging box lid is opened. For more information on pairing, please refer to the operating instructions for the playback device. Each time the buds are used after first use, they will automatically pair with the previously connected device. If you wish to pair them with another device, please make sure you disconnect the previously connected device where possible, as the buds can only be paired with one device at a time.
ENC function
The buds are equipped with Environmental Noise Cancellation (ENC). This automatically activated technology uses additional microphones to detect disturbing background noise and filters it out using an algorithm before it is transmitted. This is particularly effective for high-frequency noises and improves voice quality during calls.
Active Noise Cancellation (ANC) / transparency mode
This product features Active Noise Cancellation (ANC) and a Transparency Mode. ANC reduces background noise. The integrated microphones pick up the background noise, processors inside the headphones analyse this noise and determine which counter-sound will best neutralise it.
The transparency mode allows background noise to filter through while you are listening to music or other audio content. Background noise is picked up by the microphones and played back using the headphones, allowing you to hear loudspeaker announcements even when music is playing.
Please see the "Touch sensor" section to learn how to activate/deactivate ANC or transparency mode.
Music and gaming modes
You can switch between Music Mode and Gaming Mode during playback. The Gaming Mode has a lower latency than the Music Mode. However, the Music Mode has a more sophisticated sound. Please see the “Touch sensor” section to learn how to activate/deactivate ANC or transparency mode.
Hands-free function
You can use your headphones as a hands-free product for your paired device. You can accept, reject and end calls provided that these functions are supported by the paired device. Please see the “Touch sensor” section for more information on how to use the product.
Voice assistant
If your paired device has a voice assistant, you can activate this function using the headphones. Please see the “Touch sensor” section for more information on how to use the product.
Video playback
You can usually adjust the sound quality during video playback by going to the settings for the paired device or the app you are using. You can also switch from Music Mode to Gaming Mode if the audio fails to sync with the video file. The lower latency may synchronise playback.
Operation
1. Switching on and off
The buds switch on automatically when you open the charging box lid and switch off again automatically when you place them back inside the charging box and close the lid. After switching them on, the headphones will sync and connect automatically. The headphones will switch off automatically after a few minutes if there is no Bluetooth connection and neither ANC nor Transparency Mode are activated. You can also switch the buds on and off manually. Please see the „Touch Sensor“ section for more information on this.
2. Touch sensor / functions
You manage the buds' different functions using the respective touch sensor on the surface of the buds. Depending on function, you will need to briefly tap or press and hold the left or right touch sensor (multiple times) until you hear confirmation that the action has been carried out.
| Turning on and off: The | buds switch on automatically using the charging box. Press and hold the touch sensor on one headphone for 5 seconds to switch both buds off manually. The buds are switched on independently of each other by pressing holding the sensor for 3 seconds. You can also press and hold the sensor in this way to reconnect the headphones, where necessary. |
| Play / pause: Tap the left or right touch sensor to pause / play audio. | |
| Previous/next Audio file: | Tap the left touch sensor twice to skip back one track. Tap the right touch sensor twice to skip to the next track. You can still skip to the next track when only the left bud is connected. |
| Answer/end phone call: | Tap the left or right touch sensor once to accept an incoming call. Tap the touch sensor again to end the call. |
| Reject phone call: Tap | the left or right touch sensor twice to reject an incoming call. |
| ANC / transparency mode: | Press and hold the right touch sensor for 2 seconds to switch between modes. The following modes are available: ANC activated, ANC deactivated and the Transparency Mode. |
| Music / gaming mode: | Gaming Mode has a lower latency than Music Mode. We therefore recommend that you switch to Gaming Mode for video playback. Music Mode has a more sophisticated sound. You can switch between the two modes by pressing and holding the left touch sensor for 2 seconds. You can still switch between ANC ON/OFF and Transparency Mode when only the left bud is connected. |
| Volume: Tap the right | touch sensor three times to increase the volume and the left touch sensor three times to decrease the volume. You can also increase the volume using the left bud when only the left bud is connected. |
| voice assistant: If your | playback device has an integrated voice assistant, you can activate this by briefly tapping the left or right touch sensor four times. |
