True wireless earbuds for comfortable phone calls and wireless music enjoyment with additional bass enhancement. The bass boost can be turned on and off with a small button on the ear cup. Bluetooth at its best: maximum freedom of movement, as the two earbuds are not connected by a cable. They support existing voice assistants Siri and Google Assistant. Thanks to the built-in microphone, you can easily switch between music playback and answering calls, so you won't miss any calls while listening to music. The excellent fit reduces unwanted outside noise, allowing you to enjoy your music without interruption. The silicone ear tips come in three different sizes (S, M, L) for a personalized, perfect fit. Particularly small and lightweight earbuds: 4 g. Secure and comfortable fit in the ear thanks to the in-ear design. Smartphone functions can be controlled via a multifunction button (e.g., answer, end, or decline calls). Music control functions (play/pause) are also available. Volume can be controlled through the voice assistants. Comes with a charging case: This allows the headset to be recharged up to 3 times on the go - thanks to the built-in battery without external power supply. Music time/talk time: 4 hours with a fully charged headset, 16 hours with the mobile docking station. The charging case features a USB-C port. The battery capacity of the charging case is indicated by 3 LEDs. System requirements: Bluetooth-enabled device. Consumer note: To pair the earbuds with the smartphone via Bluetooth, make sure to take both earbuds out of the charging case and pair them during the initial connection. If this is not done, only one earbud will connect. Please refer to the user manual.
